clearRows
void GeomVertexArrayData::clear_rows(void);

Description: Removes all of the rows in the array. Functionally equivalent to set_num_rows(0).

getArrayFormat
GeomVertexArrayFormat const *GeomVertexArrayData::get_array_format(void) const;

Description: Returns the format object that describes this array.

getClassType
static TypeHandle GeomVertexArrayData::get_class_type(void);

Undocumented function.

getDataSizeBytes
int GeomVertexArrayData::get_data_size_bytes(void) const;

Description: Returns the number of bytes stored in the array.

getModified
UpdateSeq GeomVertexArrayData::get_modified(void) const;

Description: Returns a sequence number which is guaranteed to change at least every time the array vertex data is modified.

getNumRows
int GeomVertexArrayData::get_num_rows(void) const;

Description: Returns the number of rows stored in the array, based on the number of bytes and the stride. This should be the same for all arrays within a given GeomVertexData object.

getUsageHint
GeomEnums::UsageHint GeomVertexArrayData::get_usage_hint(void) const;

Description: Returns the usage hint that describes to the rendering backend how often the vertex data will be modified and/or rendered. See geomEnums.h.

hasColumn
bool GeomVertexArrayData::has_column(InternalName const *name) const;

Description: Returns true if the array has the named column, false otherwise. This is really just a shortcut for asking the same thing from the format.

operator =
void GeomVertexArrayData::operator =(GeomVertexArrayData const &copy);

Description:

output
void GeomVertexArrayData::output(ostream &out) const;

Description:

setNumRows
bool GeomVertexArrayData::set_num_rows(int n);

Description: Sets the length of the array to n rows. Normally, you would not call this directly, since all of the arrays in a particular GeomVertexData must have the same number of rows; instead, call GeomVertexData::set_num_rows().
The return value is true if the number of rows was changed, false if the object already contained n rows (or if there was some error).
The new vertex data is initialized to 0, including the "color" column (but see GeomVertexData::set_num_rows()).

setUsageHint
void GeomVertexArrayData::set_usage_hint(GeomEnums::UsageHint usage_hint);

Description: Changes the UsageHint hint for this array. See get_usage_hint().

write
void GeomVertexArrayData::write(ostream &out, int indent_level = (0)) const;

Description:

getClassType
static TypeHandle TypedWritableReferenceCount::get_class_type(void);

Undocumented function.

getClassType
static TypeHandle TypedWritable::get_class_type(void);

Undocumented function.

getBestParentFromSet
int TypedObject::get_best_parent_from_Set(set< int > const &) const;

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

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
int 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.
The return value is the new reference count.

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.

unref
int 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().
