Method Detail

onHeader

javaslang.control.Validation<javaslang.collection.List<SMFErrorType>,javaslang.collection.SortedMap<Integer,SMFByteBufferPackingConfiguration>> onHeader(SMFHeader header)

A function that is evaluated for a parsed header. The function must return exactly one SMFByteBufferPackingConfiguration for each ByteBuffer that should be created to hold attribute data.

Parameters:

header - The parsed header

Returns:

A set of packing configurations, or a list of reasons why packing could not proceed

onShouldPackTriangles

boolean onShouldPackTriangles()

Returns:

true iff triangles should be packed

onAllocateTriangleBuffer

ByteBuffer onAllocateTriangleBuffer(SMFTriangles triangles,
                                    long size)

A function that will allocate a ByteBuffer to hold triangle data.

Parameters:

triangles - Information about the triangles

size - The required size in octets of the allocated buffer

Returns:

A buffer of size octets

onAllocateAttributeBuffer

ByteBuffer onAllocateAttributeBuffer(Integer id,
                                     SMFByteBufferPackingConfiguration config,
                                     long size)

A function that will allocate a ByteBuffer to hold attribute data.

Parameters:

id - The configuration key

config - The packing configuration

size - The required size in octets of the allocated buffer

Returns:

A buffer of size octets
