Method Detail

evaluateChildSyntax

void evaluateChildSyntax(java.util.List<ZbnfSyntaxPrescript> childScript,
                         GenZbnfJavaData.SubClassZbnf classData,
                         boolean bList,
                         int level)
                  throws java.lang.Exception

An syntax item can have an inner syntax tree. It is not a component. The result of the inner tree is stored in the same level. If a called component is found, it is checked whether it has an own semantic and the component's syntax is not contained in #idxCmpnWithoutSemantic ( name::=<?> ) Then it is added to build a new class. If it has not a semantic, the called component is expand here.

Parameters:

childScript -

bList -

level -

Throws:

java.io.IOException

java.lang.Exception

getRegisterSubclass

private GenZbnfJavaData.SubClassZbnf getRegisterSubclass(java.lang.String name,
                                                         ZbnfSyntaxPrescript syntaxItem)

evaluateSubCmpnCall

private void evaluateSubCmpnCall(ZbnfSyntaxPrescript item,
                                 GenZbnfJavaData.SubClassZbnf classData,
                                 boolean bList,
                                 int level)
                          throws java.lang.Exception

This routine is called for <cmpnSyntax...>.

• The component is searched in GenZbnfJavaData.idxSubSyntax. It should be found, elsewhere it is an IllegalArgumentException
• The semantic is taken either from the component's definition if it is not given on the item. In this case it is written in source like <component> and item[@link #sSemantic} contains "@"-
• In that case the semantic is usual the syntax identifier.
• In that case it can be abbreviating because component::=<?semantic> is given.
• In that case the semantic can be null if component::=<?> is given. See next List.
• The semantic is taken from the item if <component?semantic> is given.
• The semantic is null if <component?> is given.

Depending on semantic == null:

• If the semantic is null, then the component's syntax definition is used and the component's data are created in this class.
• If the semantic is given then a container for the component's data is created in this class via #wrVariable(String, String, boolean, boolean) and the component's name is #registerCmpn(String) to create a class for it later if not created already.

Parameters:

item - The calling item of the component

bList - true if the syntax is part of a repetition

level -

Throws:

java.io.IOException

java.lang.Exception

wrVariable

protected void wrVariable(GenZbnfJavaData.SubClassZbnf classData,
                          java.lang.String typeNs,
                          java.lang.String typeRef,
                          java.lang.String typeObj,
                          java.lang.String semantic,
                          ZbnfSyntaxPrescript syntaxitem,
                          boolean bListVar,
                          boolean bCmpn,
                          java.util.List<java.lang.String> obligateAttribs)
                   throws java.lang.Exception

Throws:

java.lang.Exception

registerCmpn

private void registerCmpn(ZbnfSyntaxPrescript cmpn)

Registers a need Component. It is invoked either on usage of a component, or for all existing component definitions. Invocation on usage only means unused components do not create classes. If a component's start item is already registered, it is not done twice.

Parameters:

cmpn - The syntax definition head item of the components definition. It is either a name::=... or also a {<?*name>...}
