• 2022-06-06 Argument for typeNs prepared, due to GenJavaOutClass change.
• 2022-05-13 Hartmut new: regards #bOnlyOneEach ?& to prevent a container for parse result, only one element.
• 2022-04-30 Hartmut: {<?*semantic>... is a component, on calling WrClassZbnf#wrVariable(SubClassZbnf, String, String, String, String, ZbnfSyntaxPrescript, boolean, boolean, List) called in WrClassZbnf#evaluateChildSyntax(List, SubClassZbnf, boolean, int). There also: regarded there: ZbnfSyntaxPrescript.EType.kStoreSrc
• 2022-02-18 Hartmut: Improvements for basic types, now proper without manual corrections: The typeNs argument should be null for basic types. It is tested. The value of typeNs is yet not used, here some improvement opportunities TODO.
• 2022-02-11 Hartmut only adaptions to changed GenJavaOutClass
• 2022-02-07 Hartmut chg WrClassZbnf#evaluateChildSyntax(List, boolean, int):
  • If ZbnfSyntaxPrescript.bAssignIntoNextComponent is set, this element must not placed in the current class.
  • Instead, in the syntax.zbnf an element <...?+!...> should be defined, not for parsing, only for generating here. See kOnlyMarker
  • semantic = "@", this marker is used to set the semantic from ZbnfSyntaxPrescript.sDefinitionIdent, must regard here, not done in past...?
  • Now ZbnfSyntaxPrescript.RepetitionSyntax.bOnlyOneEachOption is regarded to prevent producing a List for the elements.
• 2022-02-07 Hartmut chg WrClassZbnf#wrVariable(String, String, ZbnfSyntaxPrescript, boolean, boolean, List): better error report.
• 2021-11-25 Hartmut chg {@link CmdLine}: Argument -dirJava:$(ENV)/... can contain now environment variables which are resolved using {@link Arguments#replaceEnv(String)}.
• 2021-11-25 Hartmut chg {@link #evaluateSyntax(ZbnfSyntaxPrescript)} better error message, write what is faulty.
• 2021-11-25 Hartmut chg #evaluateChildSyntax(...) argument item in the moment bad commented.
• 2020-07-16 Hartmut chg using LinkedList instead ArrayList. Question of philosophy.
• 2020-07-16 Hartmut new regard <...?""...> store as String and as parsed data.
• 2019-12-08 new control of class name with component::=<name>
• 2019-12-08 Hartmut only formally gardening (prevent warnings)
• 2019-08-17 Hartmut divided in 2 classes, the {@link GenJavaOutClass} has gotten most content from here, but that class is used from {@link org.vishia.xmlReader.GenXmlCfgJavaData} too with common approaches.
• 2019-05-14 Hartmut creation
