class | GeomVertexArrayData |
This data object is returned by GeomVertexArrayData::get_handle() or modify_handle().
As long as it exists, the data is locked; when the last of these destructs, the data is unlocked.
Only one thread at a time may lock the data; other threads attempting to lock the data will block. A given thread may simultaneously lock the data multiple times.
This class serves in lieu of a pair of GeomVertexArrayDataPipelineReader and GeomVertexArrayDataPipelineWriter classes

void GeomVertexArrayDataHandle::copy_data_from | ( | const GeomVertexArrayDataHandle * | other | ) |
Copies the entire data array from the other object.

Copies a portion of the data array from the other object into a portion of the data array of this object.
If to_size != from_size, the size of this data array is adjusted accordingly.

string GeomVertexArrayDataHandle::get_data | ( | ) | const [inline] |
Returns the entire raw data of the GeomVertexArrayData object, formatted as a string.
This is primarily for the benefit of high-level languages such as Python.

const unsigned char * GeomVertexArrayDataHandle::get_read_pointer | ( | bool | force | ) | const [inline] |
Returns a readable pointer to the beginning of the actual data stream, or NULL if the data is not currently resident.
If the data is not currently resident, this will implicitly request it to become resident soon.
If force is true, this method will never return NULL, but may block until the data is available.

bool GeomVertexArrayDataHandle::request_resident | ( | ) | const [inline] |
Returns true if the vertex data is currently resident in memory.
If this returns true, the next call to get_handle()->get_read_pointer() will probably not block. If this returns false, the vertex data will be brought back into memory shortly; try again later.
