Member Function Documentation

int DepthTestAttrib::compare_to_impl ( const RenderAttrib other) const [protected, virtual]

Intended to be overridden by derived DepthTestAttrib types to return a unique number indicating whether this DepthTestAttrib is equivalent to the other one.

This should return 0 if the two DepthTestAttrib objects are equivalent, a number less than zero if this one should be sorted before the other one, and a number greater than zero otherwise.

This will only be called with two DepthTestAttrib objects whose get_type() functions return the same.

Reimplemented from RenderAttrib.

Definition at line 76 of file depthTestAttrib.cxx.

void DepthTestAttrib::fillin ( DatagramIterator scan,
BamReader manager 
) [protected, virtual]

This internal function is called by make_from_bam to read in all of the relevant data from the BamFile for the new DepthTestAttrib.

TypedWritable * DepthTestAttrib::make_from_bam ( const FactoryParams params) [static, protected]

This function is called by the BamReader's factory when a new object of type DepthTestAttrib is encountered in the Bam file.

It should create the DepthTestAttrib and extract its information from the file.
