class GeomVertexFormat

Detailed Description

This describes the structure of a single array within a Geom data.

See GeomVertexFormat for the parent class which collects together all of the individual GeomVertexArrayFormat objects.

A particular array may include any number of standard or user-defined columns. All columns consist of a sequence of one or more numeric values, packed in any of a variety of formats; the semantic meaning of each column is defined in general with its contents member, and in particular by its name. The standard array types used most often are named "vertex", "normal", "texcoord", and "color"; other kinds of data may be piggybacked into the data record simply by choosing a unique name.

Member Function Documentation

int GeomVertexArrayFormat::add_column ( InternalName name,
int  num_components,
GeomVertexArrayFormat::NumericType  numeric_type,
GeomVertexArrayFormat::Contents  contents,
int  start = -1 
)

Adds a new column to the specification.

This is a table of per-vertex floating-point numbers such as "vertex" or "normal"; you must specify where in each record the table starts, and how many components (dimensions) exist per vertex.

The return value is the index number of the new data type.

int GeomVertexArrayFormat::add_column ( const GeomVertexColumn column)

Adds a new column to the specification.

This is a table of per-vertex floating-point numbers such as "vertex" or "normal"; you must specify where in each record the table starts, and how many components (dimensions) exist per vertex.

Adding a column with the same name as a previous type, or that overlaps with one or more previous types, quietly removes the previous type(s).

The return value is the index number of the new data type.

ReferenceCount * TypedWritableReferenceCount::as_reference_count ( ) [virtual, inherited]

Returns the pointer cast to a ReferenceCount pointer, if it is in fact of that type.

Reimplemented from TypedWritable.

Definition at line 26 of file typedWritableReferenceCount.cxx.

TypedObject * TypedObject::as_typed_object ( ) [inline, inherited]

Returns the object, upcast (if necessary) to a TypedObject pointer.

Definition at line 99 of file typedObject.I.

const TypedObject * TypedObject::as_typed_object ( ) const [inline, inherited]

Returns the object, upcast (if necessary) to a TypedObject pointer.

Definition at line 110 of file typedObject.I.

void GeomVertexArrayFormat::clear_columns ( )

Removes all columns previously added, sets the stride to zero, and prepares to start over.

int GeomVertexArrayFormat::complete_pointers ( TypedWritable **  p_list,
BamReader manager 
) [virtual]

Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().

Returns the number of pointers processed.

Reimplemented from TypedWritable.

Definition at line 667 of file geomVertexArrayFormat.cxx.

References GeomVertexColumn::complete_pointers().

int GeomVertexArrayFormat::count_unused_space ( ) const

Returns the number of bytes per row that are not assigned to any column.

Definition at line 444 of file geomVertexArrayFormat.cxx.

References GeomVertexColumn::get_start(), and GeomVertexColumn::get_total_bytes().

bool TypedWritable::decode_raw_from_bam_stream ( TypedWritable *&  ptr,
ReferenceCount *&  ref_ptr,
const string &  data,
BamReader reader = NULL 
) [static, inherited]

Reads the string created by a previous call to encode_to_bam_stream(), and extracts the single object on that string.

Returns true on success, false on on error.

This variant sets the TypedWritable and ReferenceCount pointers separately; both are pointers to the same object. The reference count is not incremented; it is the caller's responsibility to manage the reference count.

Note that this method cannot be used to retrieve objects that do not inherit from ReferenceCount, because these objects cannot persist beyond the lifetime of the BamReader that reads them. To retrieve these objects from a bam stream, you must construct a BamReader directly.

If you happen to know that the particular object in question inherits from TypedWritableReferenceCount or PandaNode, consider calling the variant of decode_from_bam_stream() defined for those methods, which presents a simpler interface.

string TypedWritable::encode_to_bam_stream ( ) const [inline, inherited]

Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a string string.

Returns empty string on failure.

This is a convenience method particularly useful for cases when you are only serializing a single object. If you have many objects to process, it is more efficient to use the same BamWriter to serialize all of them together.

bool TypedWritable::encode_to_bam_stream ( string &  data,

void ReferenceCount::local_object ( ) [inline, inherited]

This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.

This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

This function is called by the BamReader's factory when a new object of type GeomVertexArrayFormat is encountered in the Bam file.

void TypedWritable::mark_bam_modified ( ) [inline, inherited]
void GeomVertexArrayFormat::pack_columns ( )
void 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.
