Member Function Documentation

void Falcon::SrcLexer::appendStream

(

Stream *

s

)

int Falcon::SrcLexer::character

(

)

const [inline]

Return current character position in current line (starting from 1).

int Falcon::SrcLexer::contextStart

(

)

Gets the line at which the current context started.

Returns:

0 if no context is open, a valid line otherwise.

t_contextType Falcon::SrcLexer::currentContext

(

)

Reads the current context type.

Returns:

ct_top if outside any context.

int Falcon::SrcLexer::doLex

(

void *

param

)

[inline]

Hook for bison.

Bison will call this with his "parameter", which is the value of the various expression. The type for lexed values is the lex_value_t union, declared in the bison files.

bool Falcon::SrcLexer::hasOpenContexts

(

)

[inline]

void Falcon::SrcLexer::incremental

(

bool

b

)

[inline]

bool Falcon::SrcLexer::incremental

(

)

const [inline]

bool Falcon::SrcLexer::inParCtx

(

)

Determines if the current context is a parentetic context.

Returns:

true if in parenthesis.

Stream* Falcon::SrcLexer::input

(

)

const [inline]

void Falcon::SrcLexer::input

(

Stream *

i

)

int Falcon::SrcLexer::lex

(

)

void Falcon::SrcLexer::line

(

int

val

)

[inline]

int Falcon::SrcLexer::line

(

)

const [inline]

Return current line in file (starting from 1).

void Falcon::SrcLexer::parseMacro

(

)

void Falcon::SrcLexer::parseMacroCall

(

)

void Falcon::SrcLexer::parsingFtd

(

bool

b

)

bool Falcon::SrcLexer::parsingFtd

(

)

const [inline]

bool Falcon::SrcLexer::popContext

(

)

Pops a compilation lexer context.

Returns:

true if the contest was popped, false if we had no context.

int Falcon::SrcLexer::previousLine

(

)

const [inline]

void Falcon::SrcLexer::pushContext	(	t_contextType	ct,
		int	startLine
	)

Add a compilation lexer context.

bool Falcon::SrcLexer::readAhead

(

uint32 &

chr

)

Specialized version of ReadAhead, killing unneeded \r.

Returns:

true if the character could be read ahead

Parameters:

chr

Where to place the read character

void Falcon::SrcLexer::reset

(

)

Resets the lexer, preparing it for another compilation.

void Falcon::SrcLexer::resetContexts

(

)

void* Falcon::SrcLexer::value

(

)
