Change Log

Version 1.2.10 2017-07-30
  • Added method "MD5.of(InputStream)".
  • Added utility class "de.unkrig.commons.lang.Comparators".
  • CompressUtil: The "UnsupportedZipFeatureException" was not properly wrapped because it has none of the "usual" constructors that "ExceptionUtil.wrap()" requires.
  • Added "InputStreams.readAll(InputStream, boolean closeInputStream)".
  • de.unkrig.commons.util.collections.Peekerators: Introduced the concept of the "peekerator" - an Iterator with a "peek()" method.
  • IterableUtil: Added "IterableUtil.NATURALS" and "NATURALS0".
  • de.unkrig.commons.util.collections: Added methods "IteratorUtil.foR(...)" and "IterableUtil.foR(...)".
  • de.unkrig.commons.util.collections: Moved "iteratorWithContext()" from IterableUtil to IteratorUtil.
  • de.unkrig.commons.util.collections: Made "ElementWithContext" a top-level type, because it is now used by two compilation units (IteratorUtil and IterableUtil).
  • commons-net and commons-util: Moved the "CustomAuthenticator" (and its fellows "CredentialsSpec", "JPasswordFields" and "Regex" from the ANTOLOGY project to the "de.unkrig.commons.net" project, where it belongs.
  • CommandLineOptions: Gave "printResource(Class, String relativeResourceName, ...)" a sibling method "printResource(ClassLoader, String resourceName, ...)".
  • de.unkrig.commons.net.http.HttpMessage: In "attempt unstreaming" mode, the body was written TWICE (caused IllegalStateExceptions).
  • de.unkrig.commons.net.http: Added support for the "CONNECT" method.
  • Added to many methods parameter(s) "xxxLoggingPrefix" so that one can customize the logging messages. By default, logging messages related to incoming data are prefixed with ">>> ", and logging messages related to outgoing data with "<<< ".
  • HttpMessage: The "attempt unstreaming" feature can now be switched off (important for the CONNECT method).
  • "IoUtil.copy()" now flushes the output stream when the next READ from the input stream will block.
  • de.unkrig.commons.text.expression: Added support for nested types.
  • Changed the return types of "Expression.evaluateTo[Primitive](...)" from "Object" to "T".
  • AuthenticateHeaderParser: Implemented BASIC authentication for the "HttpClient" - useful to configure HTTP proxies that handle authentication.
  • unkrig.commons/text/scanner: Added "String[] Token.captured" for access to input subsequences that were captured during the token match.
  • ConsumerUtil: Added methods "head(m)" and "tail(n)".
  • "Transformer" now extends "TransformerWhichThrows<I, O, RuntimeException>", as it always should have done.
  • Added "BooleanProducer ProducerUtil.once()".
  • Added the "de.unkrig.commons.text.scanner.XmlScanner" class and tests.
  • Added "StringUtil.containsAny(String subject, String characters)", which checks whether the subject contains any of the characters.
  • Added the "FilterAppendable", very much in anaolgy with the "java.io.FilterWriter".
  • Added "CharSequences.from(char[])" and "CharSequences.from(char[], int off, int len)".
  • Added the "Appendables" utility class.
  • de.unkrig.commons.doclet.html.Html: Added support for {@value} on enum constants.
  • de.unkrig.commons.doclet.html.Html: STANDARD_LINK_MAKER: Added support for links to enum constants.
  • de.unkrig.commons.text.expression.ExpressionEvaluator: Breaking API change: "evaluateTo(..)" now returns a _nullable_ result.
  • ConsumerUtil: Added various "store()" and "cumulate()" methods.
  • de.unkrig.commons.net.http.HttpMessage: Added method "body(final ProducerWhichThrows<InputStream, IOException> in)".
  • Automatic XML formatting is now not only active for content type "text/xml", but for any content type with an infix "xml".
  • de.unkrig.commons.io.ReaderInputStream: First implementation of the "ReaderInputStream" as the complement of the "WriterOutputStream"; as of now supports only char set ISO8859-1.
  • TransformingFilterReader: Bug fixed: "TransformingFilterReader.read()" returned -1 on the first pattern match.
  • de.unkrig.commons.doclet.html.Html: @value: The argument was not SGML-Escaped.
  • TransformerUtil: Added "cache(final Transformer<? super I, O> delegate, final Map<I, O> cache)".
  • ContentsProcessings.processArchive(): "Directory archive entries" are now silently ignored, because they have no contents and thus it makes no sense to process them with the "contentsProcessor".
  • FileUtil: Added a workaround for MS WINDOWS 7: Read-protected directory produces: isDirectory() => true; canRead() => true; list() => null; listFiles() => null (Caused NPEs.)
  • PasswordAuthenticationStores: "..customAuthenticator_credentials,orig" file was not deleted after saving the credentials properties file.
Version 1.2.9 2017-02-02
  • de.unkrig.commons.crypto/security: Gave up on the concept of "DestroyableString"s - they cause more confusion than they are helpful.
  • ProducerUtil: Fixed a serious bug in "cacheAsynchronously()": ExecutionExceptions thrown by the Future were not handled properly and caused the cache to "hang".
  • Added "roundRobin()".
Version 1.2.8 2017-01-27
  • New utility class "AssertString": Provides methods like "assertContains(String expectedInfix, String actual)".
  • Added a new package "de.unkrig.commons.lang.crypto", and moved many classes from "lang.security" to there.
  • Extracted the UserNamePasswordStore from "de.unkrig.antology.task.SetAuthenticatorTask" to here.
  • Added "StatefulScanner.getCurrentState()" and "setCurrentState()" so that the state of the scanner can be changed from outside admidst scanning.
  • Added "AbstractScanner.suppress(TT)" and "suppress(EnumSet<TT>)".
  • Added "ProducterUtil.filter(Producer, Predicate)".
  • StatefulScanner: Declared a constant "REMAIN" for the "addRule()" methods that have a final "nextState" parameter.
  • AbstractParser: End-of-input handling was brooken in "read(Object... tokenTypeOrText)".
  • Added the "de.unkrig.commons.lang.Characters" utility class.
  • The first parameter of methods "StatefulScanner.addRule(EnumSet<S>, ...)" is now NULLABLE, where "null" means "any state, including the default state".
  • Added a constructor "StatefulScanner(StatefulScanner)" that clones the configuration, but not the state.
  • StatefulScanner: Added methods "addRule(@Nullable EnumSet<S> states, String regex, TT tokenType)" and "addRule(@Nullable EnumSet<S> states, String regex, TT tokenType, S nextState)", which make it easier to declare rules that apply in more than one non-default states.
  • Fixed one major design error in "CommandLineOptions": Method "applyCommandLineOption()" now gets a "Method" as its second parameter, instead of, previously, a "CommandLineOption" object.
Version 1.2.7 2016-12-12
  • IoUtil: Added "singlingFilterReader()" and "singlingInputStream()".
  • PatternUtil: Fixed several bugs in "PatternUtil.replaceAll()".
  • PatternUtil: Added "replaceAllFilterReader()".
  • PatternUtil: Added "replaceAllFilterWriter()".
  • Moved many, many methods from "IoUtil" to the new utility classes "InputStreams", "OutputStreams", "Readers", "Writers" and "FransformingFilter(Reader|Writer)".
  • Added "StringTransformers", a collection of simple "Transformer<CharSequence, CharSequence>"s.
  • Added TransformerUtil.chain(Transformer...)".
  • Extracted "PatternUtil.replaceAllFilterReader()" as the new "Substitutor" class.
  • Adapted to the refactoring of "IoUtil".
  • Added unit tests for the "Substitutor".
  • "IoUtil.findOnPath()": The search stopped at the FIRST archive file.
Version 1.2.6 2016-11-30
  • commons-io: Added the "CharFilter", "CharFilterReader" and "CharFilterWrite", which are the char-wise equivalent of "ByteFilter(InputStream|OutputStream)?".
  • Glob: Added the "" special case for the "container match".
  • FileProcessings, ContentsProcessings: The "pathPredicate" was missing from content processors.
Version 1.2.5 2016-11-28
  • Printers: Added "Printers.redirectToFile(Level|EnumSet<Level>)".
Version 1.2.4 2016-11-25
  • IoUtil: Fixed one MalformedURLException.
  • Added the "ByteFilterOutputStream", as a complement to the "ByteFilterInputStream".
  • ContentsTransformations: Added methods "chain(ContentsTransformer, ContentsTransformer)", "asInputStream(InputStream delegate, ContentsTransformer, String)" and "asOutputStream(ContentsTransformer, OutputStream delegate, name)".
  • Added "SelectiveContentsTransformer.create()", which can conduct many optimizations.
  • Workover of the "Printers" API: A lot of functionality went from "Printers" to "AbstractPrinter"; the old methods, however, remain, and are now marked as @deprecated.
  • IoUtil: Added methods "findOnPath(File[], String resourceName)" and "copyTree(URL, File)".
  • Added "de.unkrig.commons.lang.ClassLoaders".
  • Slightly clarified the wording of the license: Replaced "author" with "copyright holder and its contributors".
Version 1.2.3, 2016-11-07
  • commons-file: The "formats" files didn't make it into the JAR, because they were in "src/main/java" instead of "src/main/resource".
Version 1.2.2, 2016-11-07
  • XmlUtil.parse(): Detect and throw IOExceptions (esp. FileNotFoundException) properly.
  • commons-junit4: Removed the unnecessary dependency on "org.apache.commons:commons-compress".
  • For unknown reasons, the POM of org.apache.commons:commons-compress fails to declare the dependency on "org.tukaani:xz", although it definitely depends on it. Thus added the dependency in "de.unkrig.commons:commons-file"'s POM.
  • "IoUtil.parallel()", as a side effect, caused the JVM to not terminate when it is shut down orderly (i.e. "main()" returns or "System.exit()" is invoked).
  • Added "ThreadUtil.DAEMON_THREAD_FACTORY".
Version 1.2.1, 2016-10-30
  • Removed the nasty circular dependencies around "commons-junit".

  • Bug fixes in "ProducerUtil.cache()".
Version 1.1.11, 2016-08-13
  • ProducerUtil.cache...(): The "invalidationCondition" was treated the wrong way around in some places. Pulled things straigt.
  • PredicateUtil: Added method "static synchronizedPredicate(Predicate)".
Version 1.1.10, 2016-08-12
  • ProducerUtil.cache(): When the first call of "delegate.produce()" threw an exception, then the NEXT invocation returned NULL (instead of calling "delegate.produce()" again).
  • ProducerUtil: Added "cacheAsynchronously()" and "atMostEvery(ms, firstProduct, startAtTrueProduct)".
Version 1.1.9, 2016-08-02
  • Fixed the bounds of of the parameters of some "MapUtil()" methods, to make them more versatile.
Version 1.1.8, 2016-07-26
  • Moved various map-related methods from "CollectionUtil" to "MapUtil" (where they actually belong), marked the original methods with "@Deprecated" and replaced them with invocations of the "new" methods.
  • Moved a few more fields and methods from "CollectionUtil" to "IterableUtil" and "IteratorUtil", where they belong.
  • Added many missing bounds to method parameters to make the methods more flexible.
Version 1.1.7, 2016-06-17
  • Added "ObjectUtil.hashCode()".
  • Added "PredicateUtil.always(boolean)".
  • Added "PredicateUtil.xor()".

  • Added the "IdentityHashSet".
  • Added methods "Pipe.read(byte[])" and "Pipe.write(byte[])".
  • Changed type parameter "EX" of "(Consumer|Function|Predicate|Producer|Runnable|Transformer)WhichThrows" interfaces from "extends Exception" to "extends Throwable" to allow for seamless handlich of the "Longjump" throwable.
  • Added a static "ignoreExceptions()" method to the "(Consumer|Function|Predicate|Producer|Runnable|Transformer)Util" classes.
  • Longjump: Added various "catchLongjump()" methods for easy integration with Java 8 lambdas.
  • Added the following methods:
    • IoUtil.copy(File, File, CollisionStrategy)

  • Gave up on Java 5 compatibility; Java >= 6 is now required.
  • UPDATE no longer takes two separate paramaters 'glob' and 'update-file', but one parameter 'glob=update-file', which makes it possible to use variable references when creating the 'update-file' name.
  • Push releases to OSSRH and eventually to MAVEN CENTRAL
Version 1.1.0, 2015-02-04
  • Major refactoring of 'de.unkrig.commons.file.fileprocessing' and 'de.unkrig.commons.file.contentsprocessing'.
