DESCRIPTION

This class is a subclass from Class::Gomor. It implements objects as hash references, and inherits methods from Class::Gomor.

GLOBAL VARIABLE

See Class::Gomor.

METHODS

new (hash)

Object constructor. This is where user passed attributes (hash argument) are checked against valid attributes (gathered by cgGetAttributes method). Valid attributes are those that exists (doh!), and have not an undef value. The default is to check this, you can avoid it by setting $NoCheck global variable (see perldoc Class::Gomor).

cgBuildIndices

This method does nothing. It only exists to make it more easy to switch between Class::Gomor::Array and Class::Gomor::Hash.

cgBuildAccessorsScalar (array ref)
cgBuildAccessorsArray (array ref)

See Class::Gomor.

cgGetIndice (scalar)

This method does nearly nothing. It only returns the passed-in scalar parameter (so the syntax is the same as in Class::Gomor::Array). It only exists to make it more easy to switch between Class::Gomor::Array and Class::Gomor::Hash.

cgClone [ (scalar) ]

You can clone one of your objects by calling this method. An optional parameter may be used to create multiple clones. Cloning will occure only on the first level attributes, that is, if you have attributes containing other objects, they will not be cloned.

cgFullClone [ (scalar) ]

This method is the same as cgClone, but will clone all attributes recursively, but only if they are subclassed from Class::Gomor. So, objects created with other modules than Class::Gomor::Array or Class::Gomor::Hash will not be cloned.

Another thing to note, there is no catch for cycling references (when you link two objects with each others). You have been warned.

cgDumper

Will return a string as with Data::Dumper Dumper method. This is less useful for hashref objects, because they already include attributes names.
