Static Public Member Functions | |
| static TypeHandle | getClassType () |
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
| clearRows | ( | ) |
| copyDataFrom | ( | GeomVertexArrayDataHandle const | other | ) |
Copies the entire data array from the other object.
| copySubdataFrom | ( | unsigned int | to_start, |
| unsigned int | to_size, | ||
| GeomVertexArrayDataHandle const | other, | ||
| unsigned int | from_start, | ||
| unsigned int | from_size | ||
| ) |
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.
| GeomVertexArrayFormat const getArrayFormat | ( | ) |
| static TypeHandle getClassType | ( | ) | [static] |
Reimplemented from ReferenceCount.
| string getData | ( | ) |
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.
| int getDataSizeBytes | ( | ) |
| UpdateSeq getModified | ( | ) |
| int getNumRows | ( | ) |
| GeomVertexArrayData getObject | ( | ) |
| GeomVertexArrayData const getObject | ( | ) |
Returns a subset of the raw data of the GeomVertexArrayData object, formatted as a string.
This is primarily for the benefit of high-level languages such as Python.
| UsageHint getUsageHint | ( | ) |
| markUsed | ( | ) |
Marks the array data recently-used.
| bool requestResident | ( | ) |
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.
| bool reserveNumRows | ( | int | n | ) |
| setData | ( | string | data | ) |
Replaces the entire raw data array with the contents of the indicated string.
This is primarily for the benefit of high-level languages like Python.
| bool setNumRows | ( | int | n | ) |
Replaces a portion of the data array from the indicated string.
If size != data.size(), the size of this data array is adjusted accordingly.
This is primarily for the benefit of high-level languages like Python.
| bool uncleanSetNumRows | ( | int | n | ) |
