Detailed Description

This object provides a high-level interface for quickly writing a sequence of numeric values from a vertex table.

This object can be used both to replace existing vertices in the table, or to extend the table with new vertices. The set_data*() family of methods can only be used to replace existing data; it is an error to allow these to run past the end of the data. The add_data*() family of methods, on the other hand, can be used to replace existing data or add new data; if you call set_row() into the middle of existing data the add_data*() methods will behave like the corresponding set_data*(), but if they run past the end of existing data they will quietly add new vertices.

Like GeomVertexReader, the writer is particularly optimized for writing a single column of data values for a series of vertices, without changing columns between each number. Although you can also use one GeomVertexWriter to write across the columns if it is convenient, by calling set_column() repeatedly at each vertex, it is faster to write down the columns, and to use a different GeomVertexWriter for each column.

Note that, like a GeomVertexReader, a GeomVertexWriter does not keep a reference count to the actual vertex data buffer. This means that it is important not to keep a GeomVertexWriter object around over a long period of time in which the data buffer is likely to be deallocated; it is intended for making a quick pass over the data in one session.

It also means that you should create any GeomVertexWriters before creating GeomVertexReaders on the same data, since the writer itself might cause the vertex buffer to be deallocated. Better yet, use a GeomVertexRewriter if you are going to create both of them anyway.

bool hasColumn ( )

Returns true if a valid data type has been successfully set, or false if the data type does not exist.

◆ isAtEnd()

bool isAtEnd ( )

Returns true if the writer is currently at the end of the list of vertices, false otherwise.

If this is true, another call to set_data*() will result in a crash, but another call to add_data*() will add a new row.

◆ operator=()

GeomVertexWriter operator= ( const GeomVertexWriter  copy)

◆ output()

output ( Ostream  out)

◆ reserveNumRows()

bool reserveNumRows ( int  num_rows)

This ensures that enough memory space for num_rows is allocated, so that you may add up to num_rows rows without causing a new memory allocation.

This is a performance optimization only; it is especially useful when you know the number of rows you will be adding ahead of time.

◆ setColumn() [1/3]

bool setColumn ( const InternalName  name)

Sets up the writer to use the data type with the indicated name.

This also resets the write number 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.

◆ setColumn() [2/3]

bool setColumn ( int  column)

Sets up the writer to use the nth data type of the GeomVertexFormat, numbering from 0.

This also resets the write row number 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.

◆ setColumn() [3/3]

bool setColumn ( int  array,
const GeomVertexColumn  column 
)

Sets up the writer to use the indicated column description on the given array.

This also resets the current write row number 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.
