getClassType static TypeHandle AngularForce::get_class_type(void); Undocumented function.

getQuat LRotationf AngularForce::get_quat(PhysicsObject const *po); Description : access query

makeCopy virtual AngularForce *AngularForce::make_copy(void) const = 0; Undocumented function.

write virtual void AngularForce::write(ostream &out, unsigned int indent = (0)) const; Description : Write a string representation of this instance to <out>.

getActive bool BaseForce::get_active(void) const; Undocumented function.

getClassType static TypeHandle BaseForce::get_class_type(void); Undocumented function.

getForceNode ForceNode *BaseForce::get_force_node(void) const; Filename: baseForce.I Created by: charles (08Aug00) PANDA 3D SOFTWARE Copyright (c) 2001 - 2004, Disney Enterprises, Inc.

getForceNodePath NodePath BaseForce::get_force_node_path(void) const; Undocumented function.

isLinear virtual bool BaseForce::is_linear(void) const = 0; Undocumented function.

output virtual void BaseForce::output(ostream &out) const; Description : Write a string representation of this instance to <out>.

setActive void BaseForce::set_active(bool active); Undocumented function.

write virtual void BaseForce::write(ostream &out, int indent_level = (0)) const; Description : Write a string representation of this instance to <out>.

getClassType static TypeHandle TypedReferenceCount::get_class_type(void); Undocumented function.

getClassType static TypeHandle TypedObject::get_class_type(void); Undocumented function.

getType virtual TypeHandle TypedObject::get_type(void) const = 0; Derived classes should override this function to return get_class_type().

getTypeIndex int TypedObject::get_type_index(void) const; Description: 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().

isExactType bool TypedObject::is_exact_type(TypeHandle handle) const; Description: Returns true if the current object is the indicated type exactly.

isOfType bool TypedObject::is_of_type(TypeHandle handle) const; Description: Returns true if the current object is or derives from the indicated type.

getClassType static TypeHandle ReferenceCount::get_class_type(void); Undocumented function.

getRefCount int ReferenceCount::get_ref_count(void) const; Description: Returns the current reference count.

ref void ReferenceCount::ref(void) const; Description: 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.

testRefCountIntegrity bool ReferenceCount::test_ref_count_integrity(void) const; Description: Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise.

testRefCountNonzero bool ReferenceCount::test_ref_count_nonzero(void) const; Description: Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise.

unref bool ReferenceCount::unref(void) const; Description: 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. The return value is true if the new reference count is nonzero, false if it is zero.
