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

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.

const string ExecutionEnvironment::filename (   )  const

Get the current file name.

int ExecutionEnvironment::linenumber (   )  const

Get the current line number.

void ExecutionEnvironment::popframe (   )

Pop the top call frame from the backtrace stack.

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::setFilename (  const string &  filename  )

Set the current file name for error outputs.

void ExecutionEnvironment::setLinenumber (  int  line  )

Set the current line number.

void ExecutionEnvironment::setStatement (  YStatementPtr  s  )

Set the currently evaluated statement.

YStatementPtr ExecutionEnvironment::statement (   )  const

Return the currently evaluated statement.
