Detailed Description

Records a set of button events that happened recently.

This class is usually used only in the data graph, to transmit the recent button presses, but it may be used anywhere a list of ButtonEvents is desired.

void ButtonEventList::add_event ( ButtonEvent event ) [inline]

Adds a new event to the end of the list.

Definition at line 43 of file buttonEventList.I.
References _events, and INLINE.

void ButtonEventList::clear ( void ) [inline]

Empties all the events from the list.

Definition at line 92 of file buttonEventList.I.

virtual TypeHandle ButtonEventList::force_init_type ( void ) [inline, virtual]

Reimplemented from EventStoreValueBase.
Definition at line 79 of file buttonEventList.h.

TypeHandle ButtonEventList::get_class_type ( void ) [inline, static]

Reimplemented from EventStoreValueBase.
Definition at line 68 of file buttonEventList.h.

const ButtonEvent & ButtonEventList::get_event ( int n ) const [inline]

Returns the nth event in the list.
This does not remove the event from the list; the only way to remove events is to empty the whole list with clear().

int ButtonEventList::get_num_events ( ) const [inline]

Returns the number of events in the list.

int ReferenceCount::get_ref_count ( ) const [inline, inherited]

Returns the current reference count.

References list.

int TypedObject::get_type_index ( ) const [inline, inherited]

Returns the internal index number associated with this object's TypeHandle, a unique number for each different type.
This is equivalent to get_type().get_index().

void ButtonEventList::init_type ( void ) [inline, static]

Reimplemented from EventStoreValueBase.

bool TypedObject::is_exact_type ( TypeHandle handle ) const [inline, inherited]

Returns true if the current object is the indicated type exactly.

Definition at line 101 of file typedObject.I.
Referenced by PT(), and CollisionNode::xform().

bool TypedObject::is_of_type ( TypeHandle handle ) const [inline, inherited]

Returns true if the current object is or derives from the indicated type.

void ButtonEventList::output ( ostream & out ) const [virtual]

Implements EventStoreValueBase.
Definition at line 57 of file buttonEventList.cxx.

int ReferenceCount::ref ( ) const [inline, inherited]

Explicitly increments the reference count.
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is the new reference count.

void ReferenceCount::test_ref_count_integrity ( ) const [inline, inherited]

Does some easy checks to make sure that the reference count isn't completely bogus.

Definition at line 328 of file referenceCount.I.
References INLINE.
Referenced by EggNode::determine_bin(), and ReferenceCount::~ReferenceCount().

int ReferenceCount::unref ( ) const [inline, inherited]

Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

void ButtonEventList::update_mods ( ModifierButtons & mods ) const

Updates the indicated ModifierButtons object with all of the button up/down transitions indicated in the list.
