Parser

protected Parser(Compiler compiler,
                 Scanner scanner,
                 int lookahead)

Constructs a new parser instance.

Parameters:

compiler - the invoking compiler.

scanner - the token stream generator

lookahead - lookahead

Method Detail

getCompiler

public Compiler getCompiler()

Returns the compiler driver which invoked the parser.

getBuffer

public final InputBuffer getBuffer()

Returns the input buffer.

buildTokenReference

protected final TokenReference buildTokenReference()

Returns a reference to the current position in the source file.

getStatementComment

protected final JavaStyleComment[] getStatementComment()

getJavadocComment

protected final JavadocComment getJavadocComment()

getComment

protected Vector getComment()

reportTrouble

protected final void reportTrouble(PositionedError trouble)

Reports that an error has been detected in the lexical analyser. The handling is delegated to the compiler driver.

Parameters:

trouble - the error to report

beautifyParseError

public PositionedError beautifyParseError(ParserException e)

Generate an human readable error message
