This object provides the functionality of both a GeomVertexReader and a GeomVertexWriter, combined together into one convenient package.
It is designed for making a single pass over a GeomVertexData object, modifying rows as it goes.
Although it doesn't provide any real performance benefit over using a separate reader and writer on the same data, it should probably be used in preference to a separate reader and writer, because it makes an effort to manage the reference counts properly between the reader and the writer to avoid accidentally dereferencing either array while recopying.
__init__ | ( | const GeomVertexRewriter | copy | ) |
__init__ | ( | GeomVertexArrayData | array_data, |
int | column, | ||
Thread | current_thread ) |
Constructs a new rewriter to process the vertices of the indicated array only.
__init__ | ( | GeomVertexArrayData | array_data, |
Thread | current_thread ) |
Constructs a new rewriter to process the vertices of the indicated array only.
__init__ | ( | GeomVertexData | vertex_data, |
const InternalName | name, | ||
Thread | current_thread ) |
Constructs a new rewriter to process the vertices of the indicated data object.
This flavor creates the rewriter specifically to process the named data type.
__init__ | ( | GeomVertexData | vertex_data, |
Thread | current_thread ) |
Constructs a new rewriter to process the vertices of the indicated data object.
__init__ | ( | Thread | current_thread | ) |
Constructs an invalid GeomVertexRewriter.
You must use the assignment operator to assign a valid GeomVertexRewriter to this object before you can use it.
clear | ( | ) |
Resets the GeomVertexRewriter to the initial state.
int getArray | ( | ) |
Returns the array index containing the data type that the rewriter is working on.
GeomVertexArrayData getArrayData | ( | ) |
Returns the particular array object that the rewriter is currently processing.
GeomVertexArrayDataHandle getArrayHandle | ( | ) |
Returns the write handle to the array object that the rewriter is currently processing.
This low-level call should be used with caution; be careful with modifying the data in the handle out from under the GeomVertexRewriter.
const GeomVertexColumn getColumn | ( | ) |
Returns the description of the data type that the rewriter is working on.
Thread getCurrentThread | ( | ) |
Returns the Thread pointer of the currently-executing thread, as passed to the constructor of this object.
int getStartRow | ( | ) |
Returns the row index at which the rewriter started.
It will return to this row if you reset the current column.
int getStride | ( | ) |
Returns the per-row stride (bytes between consecutive rows) of the underlying vertex array.
This low-level information is normally not needed to use the GeomVertexRewriter directly.
GeomVertexData getVertexData | ( | ) |
Returns the vertex data object that the rewriter is processing.
bool hasColumn | ( | ) |
Returns true if a valid data type has been successfully set, or false if the data type does not exist.
bool isAtEnd | ( | ) |
Returns true if the reader or writer is currently at the end of the list of vertices, false otherwise.
GeomVertexRewriter operator= | ( | const GeomVertexRewriter | copy | ) |
output | ( | Ostream | out | ) |
bool setColumn | ( | const InternalName | name | ) |
Sets up the rewriter to use the data type with the indicated name.
This also resets both the read and write row numbers to the start row (the same value passed to a previous call to set_row(), or 0 if set_row() was never called.)
The return value is true if the data type is valid, false otherwise.
bool setColumn | ( | int | array, |
const GeomVertexColumn | column ) |
Sets up the rewriter to use the indicated column description on the given array.
This also resets both the read and write row numbers to the start row (the same value passed to a previous call to set_row(), or 0 if set_row() was never called.)
The return value is true if the data type is valid, false otherwise.
bool setColumn | ( | int | column | ) |
Sets up the rewriter to use the nth data type of the GeomVertexFormat, numbering from 0.
This also resets both the read and write row numbers to the start row (the same value passed to a previous call to set_row(), or 0 if set_row() was never called.)
The return value is true if the data type is valid, false otherwise.
setRow | ( | int | row | ) |
Sets the start, write, and write index to the indicated value.
The rewriter will begin traversing from the given row.
setRowUnsafe | ( | int | row | ) |
Sets the start row to the indicated value, without internal checks.
This is the same as set_row(), but it does not check for the possibility that the array has been reallocated internally for some reason; use only when you are confident that the array is unchanged and you really need every bit of available performance.
