Detailed Description

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.

Returns the array index containing the data type that the rewriter is working on.

Definition at line 233 of file geomVertexRewriter.I.

◆ get_array_data()

GeomVertexArrayData * GeomVertexRewriter::get_array_data ( ) const

inline

Returns the particular array object that the rewriter is currently processing.

Definition at line 116 of file geomVertexRewriter.I.

◆ get_array_handle()

GeomVertexArrayDataHandle * GeomVertexRewriter::get_array_handle ( ) const

inline

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.

Definition at line 129 of file geomVertexRewriter.I.

References GeomVertexWriter::get_array_handle().

◆ get_column()

const GeomVertexColumn * GeomVertexRewriter::get_column ( ) const

inline

Returns the description of the data type that the rewriter is working on.

Definition at line 243 of file geomVertexRewriter.I.

◆ get_current_thread()

Thread * GeomVertexRewriter::get_current_thread ( ) const

inline

Returns the Thread pointer of the currently-executing thread, as passed to the constructor of this object.

Definition at line 149 of file geomVertexRewriter.I.

◆ get_start_row()

int GeomVertexRewriter::get_start_row ( ) const

inline

Returns the row index at which the rewriter started.

It will return to this row if you reset the current column.

Definition at line 280 of file geomVertexRewriter.I.

◆ get_stride()

size_t GeomVertexRewriter::get_stride ( ) const

inline

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.

Definition at line 139 of file geomVertexRewriter.I.

◆ get_vertex_data()

GeomVertexData * GeomVertexRewriter::get_vertex_data ( ) const

inline

Returns the vertex data object that the rewriter is processing.

Definition at line 105 of file geomVertexRewriter.I.

◆ has_column()

bool GeomVertexRewriter::has_column ( ) const

inline

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

Definition at line 222 of file geomVertexRewriter.I.

◆ is_at_end()

bool GeomVertexRewriter::is_at_end ( ) const

inline

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

◆ set_column() [1/3]

bool GeomVertexRewriter::set_column ( int column )

inline

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.

◆ set_column() [2/3]

bool GeomVertexRewriter::set_column ( CPT_InternalName name )

inline

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.

◆ set_column() [3/3]

bool GeomVertexRewriter::set_column	(	int	array,
		const GeomVertexColumn *	column
	)

inline

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.

Definition at line 201 of file geomVertexRewriter.I.

References GeomVertexReader::set_column(), and GeomVertexWriter::set_column().

◆ set_row()

void GeomVertexRewriter::set_row ( int row )

inline

Sets the start, write, and write index to the indicated value.

The rewriter will begin traversing from the given row.

Definition at line 270 of file geomVertexRewriter.I.

References GeomVertexReader::set_row(), and GeomVertexWriter::set_row().

◆ set_row_unsafe()

void GeomVertexRewriter::set_row_unsafe ( int row )

inline

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.
