Changelog

Version 1.5.0 (TBD)

  • Deprecated Transformers#keyMap in favor of Transformers#keyRename because the latter is a better semantic representation of what the transformer actaually does.
  • Added Transformers#keyRename that takes a single from key and a single to key and performs the appropriate renaming.

Version 1.4.0 (December 24, 2018)

  • Added Transformers#nest which takes another Transformer and applies it to each level of a nested data structure (e.g. Map or Sequence).
  • Added Transformers#copy which copies the value associated with one key and also associates it with another key.
  • Fixed a bug in the Transformers#valueRemoveIfEmpty factory that caused the returned Transformer to fail serialization.

Version 1.3.1 (December 5, 2018)

  • Fixed some bugs related to serializing and deserializing some built-in Transformers.
  • Added missing transformers to ensure values are handled as Strings.

Version 1.3.0 (November 23, 2018)

  • Added the ScriptedTransformer framework. ScriptedTransformer is abstract class that can be extended to provide transformation logic via a script that is compatible with the Java script engine platform. Right now, javascript is the supported language for writing transformer scripts.
  • Added support for Transformer serialization. The rules of serialization are:
    • All built-in transformers provided in the Transformers factory class are serializable.
    • ScriptedTransformers are serializable.
    • A CompositeTransformer can be serialized if all of the composed transformers can be serailized.
    • Custom transformers that require serialization should be implemented using the ScriptedTransformer framework.
  • Added Transformer#serialize and Transformer#deserialize static methods.

Version 1.2.0 (November 2, 2018)

  • Deprecated and renamed a few Transformer factories for better consistency
    • keyCaseFormat is deprecated in favor of keyConditionalConvertCaseFormat or keyEnsureCaseFormat
    • keyStripInvalidChars is deprecated in favor of keyRemoveInvalidChars
    • keyValueStripQuotes is deprecated in favor of keyValueRemoveQuotes
    • removeValuesThatAre is deprecated in favor of valueRemoveIf
    • valueSplitOnDelimiter is deprecated in favor of valueStringSplitOnDelimiter
  • Added some factories for common Transformers
    • keyEnsureCaseFormat can be used to conver ALL keys to a particular case format.
    • keyWhitespaceToUnderscore replace all whitespace characters with underscores in ALL keys
    • keyRemoveWhitespace removes all whitespace characters (no replacement) in ALL keys
    • keyRemoveInvalidChars (replacement for keyStripInvalidChars) has been overloaded to accept a collection of invalid characters in addition to a Predicate that determines if a character is invalid.
    • A version of valueRemoveIfEmpty that takes no arguments can be used to return a Transformer that removes values that match defeault definition of Empty#ness
    • Added versions of valueAsBoolean, valueAsNumber, valueAsResolvableLinkInstruction, valueAsTag and valueAsTimestamp that accept one or more keys to which the value transformation is limited. If no keys are provided, values for every key will be transformed.
  • The version of keyRemoveInvalidChars that takes a Predicate expects the predicate to determine whether the character is invalid. whereas the keyStripInvalidChars method takes a Check that is expected to determmine if a character is valid.

Version 1.1.0 (October 18, 2018)

  • Added an Transformer#transform method that takes a generic Object value parameter.
  • Added a Transformers#noOp static factory that provides a Transformer that does not perform any key or value transformations.
  • Added the following built-in Transformers:
    • explode
    • keyMap
    • valueAsBoolean
    • valueAsNumber
    • valueAsResolvableLinkInstruction
    • valueAsTag
    • valueStringToJava
    • valueAsTimestamp
    • valueNullifyIfEmpty
  • Added the Transformers#composeForEach meta transformer for applying a collection of transformers to each item within a sequence of values.
  • Added the Transfroemrs#forEach meta transformer for applying a transformer to each item within a sequence of values.

Version 1.0.0

  • Initial Release
