Member Function Documentation

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

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

This should return 0 if the two DepthWriteAttrib 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 DepthWriteAttrib objects whose get_type() functions return the same.

Reimplemented from RenderAttrib.

Definition at line 83 of file depthWriteAttrib.cxx.

void DepthWriteAttrib::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 DepthWriteAttrib.

Reimplemented from RenderAttrib.

Definition at line 158 of file depthWriteAttrib.cxx.

References DatagramIterator::get_int8().

Referenced by make_from_bam().

size_t DepthWriteAttrib::get_hash_impl ( ) const [protected, virtual]

Intended to be overridden by derived RenderAttrib types to return a unique hash for these particular properties.

RenderAttribs that compare the same with compare_to_impl(), above, should return the same hash; RenderAttribs that compare differently should return a different hash.

Reimplemented from RenderAttrib.

Definition at line 100 of file depthWriteAttrib.cxx.

References integer_hash< Key, Compare >::add_hash().

DepthWriteAttrib::Mode DepthWriteAttrib::get_mode ( ) const [inline]

Returns the depth write mode.

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

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

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

Definition at line 139 of file depthWriteAttrib.cxx.

References fillin().

Tells the BamReader how to create objects of type DepthWriteAttrib.

void DepthWriteAttrib::write_datagram ( BamWriter manager,
Datagram dg 
) [virtual]

Writes the contents of this object to the datagram for shipping out to a Bam file.

Reimplemented from RenderAttrib.
