Detailed Description

Expression Manager

Class: ExprManager

Current value of the simplifier cache tag.

The cached values of calls to Simplify are valid as long as their cache tag matches this tag. Caches can then be invalidated by incrementing this tag.

Definition at line 153 of file expr_manager.h.

Disable garbage collection.

This flag disables the garbage collection. Normally, it's set in the destructor, so that we can delete all remaining expressions without GC getting in the way.

Definition at line 159 of file expr_manager.h.

Referenced by clear(), gc(), isActive(), and ~ExprManager().

Postpone deleting garbage-collected expressions.

Useful during manipulation of context, especially at the time of backtracking, since we may have objects with circular dependencies (like find pointers).

The postponed expressions will be deleted the next time the garbage collector is called after this flag is cleared.
