NameDescription
this (filename, base, begoffset, endoffset, doDocComment, commentToken, errorSink, compileEnv) Creates a Lexer for the source code base[begoffset..endoffset+1]. The last character, base[endoffset], must be null (0) or EOF (0x1A).
this (filename, base, begoffset, endoffset, doDocComment, commentToken, whitespaceToken, errorSink, compileEnv) Alternative entry point for DMDLIB, adds whitespaceToken
this (errorSink) Used for unittests for a mock Lexer

Methods

NameDescription
allocateToken ()
combineComments (c1, c2, newParagraph) Combine two document comments into one, separated by an extra newline if newParagraph is true.
nextDefineLine () Set up for next #define line. p should be at start of next line.
parseSpecialTokenSequence () Parse special token sequence:
peekNext () Look ahead at next token's value.
peekNext2 () Look 2 tokens ahead at value.
peekPastParen (tk) tk is on the opening (. Look ahead and return token that is past the closing ).
poundLine (tok, linemarker) Parse line/file preprocessor directive: #line linnum [filespec] Allow _LINE__ for linnum, and _FILE__ for filespec. Accept linemarker format: # linnum [filespec] {flags} There can be zero or more flags, which are one of the digits 1..4, and must be in ascending order. The flags are ignored.
resetDefineLines (slice) Reset lexer to lex #define's
scan (t) Turn next token in buffer into a token.
skipToNextLine (defines) Scan forward to start of next line.
factory (classname) Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
opCmp (o) Compare with another Object obj.
opEquals (o) Test whether this is equal to o. The default implementation only compares by identity (using the is operator). Generally, overrides and overloads for opEquals should attempt to compare objects by their contents. A class will most likely want to add an overload that takes your specific type as the argument and does the content comparison. Then you can override this and forward it to your specific typed overload with a cast. Remember to check for null on the typed overload.
toHash () Compute hash function for Object.
toString () Convert Object to a human readable string.
