Constructor.

Member Function Documentation

tos()

std::ostream & Puma::Tracing::tos ( ) const

protected

Get the tracing output stream.

trace() [1/4]

void Puma::Tracing::trace ( const char * rule, int n = 1, bool quote = false )

protected

Trace the given parser rule.

Parameters

rule	The rule name.
n	The indentation depth.
quote	Quote the rule name.

trace() [2/4]

void Puma::Tracing::trace ( int token )

inlineprotected

Trace the given token.

Parameters

token

The token type.

trace() [3/4]

void Puma::Tracing::trace	(	std::ostream &	os,
		bool	trace_tokens = false )

Setup the tracer.

Parameters

os	The output stream on which to write the tracing output.
trace_tokens	Turn on/off token level tracing.

trace() [4/4]

void Puma::Tracing::trace ( Token * token, const char * ok, const char * failed )

protected

Trace the given token.

Parameters

token	The token to trace.
ok	The message if the token is not NULL.
failed	The message if the token is NULL.

trace_mode()

int Puma::Tracing::trace_mode ( ) const

inlineprotected

Get the current tracing mode.

0 means tracing is disabled, 1 means rule level tracing, 2 means token level tracing.
