genRecognizerFile

protected void genRecognizerFile(Tool tool,
                                 CodeGenerator generator,
                                 Grammar grammar,
                                 org.stringtemplate.v4.ST outputFileST)
                          throws java.io.IOException

覆盖:

genRecognizerFile 在类中 Target

抛出:

java.io.IOException

getTargetCharLiteralFromANTLRCharLiteral

public java.lang.String getTargetCharLiteralFromANTLRCharLiteral(CodeGenerator generator,
                                                                 java.lang.String literal)

从类复制的说明: Target

Convert from an ANTLR char literal found in a grammar file to an equivalent char literal in the target language. For most languages, this means leaving 'x' as 'x'. Actually, we need to escape ' ' so that it doesn't get converted to \n by the compiler. Convert the literal to the char value and then to an appropriate target char literal. Expect single quotes around the incoming literal.

覆盖:

getTargetCharLiteralFromANTLRCharLiteral 在类中 Target

getMaxCharValue

public int getMaxCharValue(CodeGenerator generator)

从类复制的说明: Target

Some targets only support ASCII or 8-bit chars/strings. For example, C++ will probably want to return 0xFF here.

覆盖:

getMaxCharValue 在类中 Target

getTokenTypeAsTargetLabel

public java.lang.String getTokenTypeAsTargetLabel(CodeGenerator generator,
                                                  int ttype)

从类复制的说明: Target

Target must be able to override the labels used for token types

覆盖:

getTokenTypeAsTargetLabel 在类中 Target

isValidActionScope

public boolean isValidActionScope(int grammarType,
                                  java.lang.String scope)

从类复制的说明: Target

Is scope in @scope::name {action} valid for this kind of grammar? Targets like C++ may want to allow new scopes like headerfile or some such. The action names themselves are not policed at the moment so targets can add template actions w/o having to recompile ANTLR.

覆盖:

isValidActionScope 在类中 Target

encodeIntAsCharEscape

public java.lang.String encodeIntAsCharEscape(int v)

覆盖:

encodeIntAsCharEscape 在类中 Target
