ZF-2104: Zend_Filter::get() docblock incorrect and needs improvement


The docblock for Zend_Filter::get() is incorrect and needs improvement.

For example, the method should be indicated to return mixed, not boolean.

Also, the docblock does not include a good description of the method's intended usage or operation.


Resolved for next minor release with SVN r8434.

Resolved for 1.5.0RC2 (next mini-release?) with SVN r8435.
