NAME

Math::Geometry::Construction::Role::Buffering - buffer results

VERSION

Version 0.018

DESCRIPTION

This role provides a hash in which results can be stored in order to prevent expensive recalculating when they are accessed. It is used by DerivedPoint and Derivate objects to store their positions.

INTERFACE

buffer

The buffer attribute implements the following hash traits (see Moose if you are not familiar with traits and native delegation):

• buffer is the name of the accessor method, which provides accessor and mutator functionality for a single entry of the hash

• delete_buffer is the name of the delete method, which deletes a single entry of the hash

• clear_buffer is the name of the clear method, which resets the hash to the empty hash

clear_global_buffer

Calls clear_buffer on the Math::Geometry::Construction object. Mainly used as trigger for attributes. When the attribute is changed the buffer is cleared.
