bool Mezzanine::UI::ActionHandler::_HandleInput ( const Input::MetaCode & Code)

Handles input passed to this handler.

Parameters

Code	The MetaCode to be processed.

Returns: Returns true if this input was consumed/handled, false otherwise.

Definition at line 208 of file actionhandler.cpp.

void Mezzanine::UI::ActionHandler::_NotifyActionActivated ( Action * BeingActivated)

Used by Actions to notify this handler it was activated.

Parameters

BeingActivated The Action calling this method and being activated.

Definition at line 198 of file actionhandler.cpp.

void Mezzanine::UI::ActionHandler::_ProcessAllActions ( )

Processes all active actions, and deactivates them if necessary.

Definition at line 219 of file actionhandler.cpp.

ActionHandler::ActionIterator Mezzanine::UI::ActionHandler::BeginAction ( )

Gets an iterator to the first Action.

Returns: Returns an iterator to the first Action stored by this handler.

Definition at line 104 of file actionhandler.cpp.

ActionHandler::ConstActionIterator Mezzanine::UI::ActionHandler::BeginAction ( ) const

Gets a const iterator to the first Action.

Returns: Returns a const iterator to the first Action stored by this handler.

Definition at line 114 of file actionhandler.cpp.

ActionHandler::BindingIterator Mezzanine::UI::ActionHandler::BeginBinding ( )

Gets an iterator to the first Binding.

Returns: Returns an iterator to the first Binding stored by this handler.

Definition at line 175 of file actionhandler.cpp.

ActionHandler::ConstBindingIterator Mezzanine::UI::ActionHandler::BeginBinding ( ) const

Gets a const iterator to the first Binding.

Returns: Returns a const iterator to the first Binding stored by this handler.

Definition at line 185 of file actionhandler.cpp.

void Mezzanine::UI::ActionHandler::Bind	(	const Input::MetaCode &	Code,
		Action *	ToBind,
		bool	ForceUnique = `true`
	)

Binds a MetaCode to an action, making the action fire when this handler recieves the code.

Note: Only one Action can be bound to a given code. Binding a second Action to a code will unbind the first.

Parameters

Code	The code to trigger the Action.
ToBind	The Action to be triggered.
ForceUnique	If true this will clear any previous entries that are equal to the MetaCode provided in the binding multimap.

Definition at line 132 of file actionhandler.cpp.

Action * Mezzanine::UI::ActionHandler::CreateAction ( const String & Name)

Creates a new Action that can be bound to a MetaCode.

Parameters

Name	The name to be given to the created Action.

Returns: Returns a pointer to the created Action.

Definition at line 63 of file actionhandler.cpp.

void Mezzanine::UI::ActionHandler::DestroyAction ( Action * ToBeDestroyed)

Destroy's an action.

Parameters

ToBeDestroyed The action to be destroyed.

Definition at line 83 of file actionhandler.cpp.

ActionHandler::ActionIterator Mezzanine::UI::ActionHandler::EndAction ( )

Gets an iterator to one-passed-the-last Action.

Returns: Returns an iterator to one-passed-the-last Action stored by this handler.

Definition at line 109 of file actionhandler.cpp.

ActionHandler::ConstActionIterator Mezzanine::UI::ActionHandler::EndAction ( ) const

Gets a const iterator to one-passed-the-last Action.

Returns: Returns a const iterator to one-passed-the-last Action stored by this handler.

Definition at line 119 of file actionhandler.cpp.

ActionHandler::BindingIterator Mezzanine::UI::ActionHandler::EndBinding ( )

Gets an iterator to one-passed-the-last Binding.

Returns: Returns an iterator to one-passed-the-last Binding stored by this handler.

Definition at line 180 of file actionhandler.cpp.

ActionHandler::ConstBindingIterator Mezzanine::UI::ActionHandler::EndBinding ( ) const

Gets a const iterator to one-passed-the-last Binding.

Returns: Returns a const iterator to one-passed-the-last Binding stored by this handler.

Definition at line 190 of file actionhandler.cpp.

Action * Mezzanine::UI::ActionHandler::GetAction ( const String & Name)

Gets an Action by name.

Parameters

Name	The name of the Action to retrieve.

Returns: Returns a pointer to the named Action.

Definition at line 76 of file actionhandler.cpp.

ActionHandler::ConstBindingRange Mezzanine::UI::ActionHandler::GetActionsBoundToCode ( const Input::MetaCode & Code)

Gets all Actions bound to a MetaCode.

Parameters

Code	The MetaCode to use to search for bound Actions.

Returns: Returns the first and one-passed-the-last iterators representing all of the Actions bound to the provided code.

Definition at line 127 of file actionhandler.cpp.

void Mezzanine::UI::ActionHandler::Unbind ( const Input::MetaCode & Code)

Unbinds Actions via MetaCode.

Note: This can unbind multiple Actions.

Parameters

Code	The MetaCode to find and remove all bindings to actions.

Definition at line 146 of file actionhandler.cpp.

void Mezzanine::UI::ActionHandler::Unbind ( Action * ToUnbind)

Unbinds an Action via Action pointer.

Note: This method will iterate over all the elements in the binding multimap in search of all bindings to the provided Action.

Parameters

ToUnbind The Action to unbind from any and all MetaCodes.

Definition at line 153 of file actionhandler.cpp.

void Mezzanine::UI::ActionHandler::UnbindAll ( )

Unbinds all actions in this handler.

Note: This does not delete entries for MetaCodeKey's, this simply sets the Action value to NULL.
