CompilationHandler

# 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:

  1. 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.

  2. 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.

  3. 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).
