Detailed Description

Class to track current execution environment. Typically used for logging and debugging.

m_forced_filename is a way to enforce a given filename until another block is entered (or the current one is left). Used for include statements, where top level block does not exist.

Member Function Documentation

int ExecutionEnvironment::linenumber

(

)

const

Get the current line number.

void ExecutionEnvironment::setLinenumber

(

int

line

)

Set the current line number.

const string ExecutionEnvironment::filename

(

)

const

Get the current file name.

void ExecutionEnvironment::setFilename

(

const string &

filename

)

Set the current file name for error outputs.

YStatementPtr ExecutionEnvironment::statement

(

)

const

Return the currently evaluated statement.

void ExecutionEnvironment::setStatement

(

YStatementPtr

s

)

Set the currently evaluated statement.

void ExecutionEnvironment::pushframe

(

string

called_function

)

Push another call frame to the backtrace stack according to the current information.

Parameters:

called_function

name of the function to be called at this point

void ExecutionEnvironment::popframe

(

)

Pop the top call frame from the backtrace stack.

void ExecutionEnvironment::backtrace	(	loglevel_t	level,
		uint	skip = 0
	)			const

Report the current backtrace to log.

Parameters:

skip

number of the top call frames to be omitted from the backtrace

ExecutionEnvironment::CallStack ExecutionEnvironment::callstack

(

)

const

Returns a copy of the call stack for debugging etc.

The stack itself may safely be modified. The pointers it contains, however, may not.
