Methods of GeomVertexReader:

Constants in GeomEnums:

clear
void GeomVertexReader::clear(void);

Description: Resets the GeomVertexReader to the initial state.

getArray
int GeomVertexReader::get_array(void) const;

Description: Returns the array index containing the data type that the reader is working on.

getArrayData
GeomVertexArrayData const *GeomVertexReader::get_array_data(void) const;

Description: Returns the particular array object that the reader is currently processing.

getColumn
GeomVertexColumn const *GeomVertexReader::get_column(void) const;

Description: Returns the description of the data type that the reader is working on.

getCurrentThread
Thread *GeomVertexReader::get_current_thread(void) const;

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

getData1f
float GeomVertexReader::get_data1f(void);

Description: Returns the data associated with the read row, expressed as a 1-component value, and advances the read row.

getData1i
int GeomVertexReader::get_data1i(void);

Description: Returns the data associated with the read row, expressed as a 1-component value, and advances the read row.

getData2f
LVecBase2f const &GeomVertexReader::get_data2f(void);

Description: Returns the data associated with the read row, expressed as a 2-component value, and advances the read row.

getData2i
int const *GeomVertexReader::get_data2i(void);

Description: Returns the data associated with the read row, expressed as a 2-component value, and advances the read row.

getData3f
LVecBase3f const &GeomVertexReader::get_data3f(void);

Description: Returns the data associated with the read row, expressed as a 3-component value, and advances the read row.

getData3i
int const *GeomVertexReader::get_data3i(void);

Description: Returns the data associated with the read row, expressed as a 3-component value, and advances the read row.

getData4f
LVecBase4f const &GeomVertexReader::get_data4f(void);

Description: Returns the data associated with the read row, expressed as a 4-component value, and advances the read row.

getData4i
int const *GeomVertexReader::get_data4i(void);

Description: Returns the data associated with the read row, expressed as a 4-component value, and advances the read row.

getReadRow
int GeomVertexReader::get_read_row(void) const;

Description: Returns the row index from which the data will be retrieved by the next call to get_data*().

getStartRow
int GeomVertexReader::get_start_row(void) const;

Description: Returns the row index at which the reader started. It will return to this row if you reset the current column.

getVertexData
GeomVertexData const *GeomVertexReader::get_vertex_data(void) const;

Description: Returns the vertex data object that the reader is processing. This may return NULL if the reader was constructed with just an array pointer.

hasColumn
bool GeomVertexReader::has_column(void) const;

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

isAtEnd
bool GeomVertexReader::is_at_end(void) const;

Description: Returns true if the reader is currently at the end of the list of vertices, false otherwise. If this is true, another call to get_data*() will result in a crash.

operator =
void GeomVertexReader::operator =(GeomVertexReader const &copy);

Description:

output
void GeomVertexReader::output(ostream &out) const;

Description:

setColumn
bool GeomVertexReader::set_column(int column);

Description: Sets up the reader to use the nth data type of the GeomVertexFormat, numbering from 0.
This also resets the read 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.
Description: Sets up the reader to use the data type with the indicated name.
Description: Sets up the reader to use the indicated column description on the given array.
This also resets the current read 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.)

setRow
void GeomVertexReader::set_row(int row);

Description: Sets the start row to the indicated value. The reader will begin reading from the indicated row; each subsequent get_data*() call will return the data from the subsequent row. If set_column() is called, the reader will return to this row.
