Class CompilationHandler
- Description
Objects used by the compiler to handle references to global symbols,
modules, external files, etc.
There can be up to three compilation handlers active at the same
time during a compilation. They are in order of precedence:
The error handler
This is the object passed to compile() as
the second argument (if any). This object is returned by
get_active_error_handler() during a compilation.
The compatibility handler
This is the object returned by
master()->get_compilation_handler() (if any), which
the compiler calls when it sees #pike-directives,
or expressions using the version scope
(eg 7.4::rusage ). This object is returned by
get_active_compilation_handler() during a compilation.
The master object.
This is returned by master() at any time.
Any of the objects may implement a subset of the CompilationHandler
functions, and the first object that implements a function will be
used. The error handler object can thus be used to block certain
functionality (eg to restrict the number of available functions).
