nameIdLocs

private int[] nameIdLocs

The following private ivars are used in parseName. They cannot be defined inside parseName because they would be reallocated at each invocation. They cannot be defined as static variables inside parseName because then the code would not be thread-safe.

nameDotLocs

private int[] nameDotLocs

public ParseType()

Method Detail

parseIdentifier

public Identifier parseIdentifier(Lex l)

Parse an Identifier.

parseName

public Name parseName(Lex l)

Parse a Name.

 Name:
 Identifier ( . Identifier ) *
 

parseTypeName

public TypeName parseTypeName(Lex l)

Parse a TypeName.

 TypeName:
 Name [TypeModifierPragmas]
 

parseBracketPairs

public Type parseBracketPairs(Lex l,
                              Type type)

Parse square bracket pairs. Wraps argument type in ArrayType objects accordingly.

 BracketPairs:
 (LSQBRACKET RSQBRACKET)*
 

Warning: when this method sees "{'[' ']'}* {'[' not-']'}", it returns with "l" pointing to the '[' just before the not-']'.

parseTypeModifierPragmas

public TypeModifierPragmaVec parseTypeModifierPragmas(Lex l)

isPrimitiveKeywordTag

public boolean isPrimitiveKeywordTag(int tag)

Returns:

is a tag a PrimitiveType keyword?

parsePrimitiveType

public PrimitiveType parsePrimitiveType(Lex l)

Parses a PrimitiveType. Returns null on failure.

   
 PrimitiveType: one of
 boolean byte short int long char float double void
 

parsePrimitiveTypeOrTypeName

public Type parsePrimitiveTypeOrTypeName(Lex l)

Parse a type, either a primitive type, a type name, but not an array type.

 PrimitiveTypeOrTypeName:
 PrimitiveType
 TypeName
 

parseType

public Type parseType(Lex l)

Parse a Type, either a primitive type, a type name, or an array type.

 Type:
