Methods

Modifier and Type	Method and Description
boolean	checkFormat(javax.media.j3d.GeometryArray ga) Check if the class, storage type, and vertex format of ga is compatible with this accessor implementation.
boolean	checkFormat(JOGLGeometry jg) this impl returns true
J3DVertexAccessor	newInstance() make a new instance of this accessor implementation
J3DVertexAccessor	read() Access the vertex storage and read the enabled vertex components at J3DVertexAccessor.componentIndex.
J3DVertexAccessor	reset(javax.media.j3d.GeometryArray ga, boolean... enableComponent) Reset this accessor so that the subsequent call to J3DVertexAccessor.next() reads the first valid vertex in ga.

Method Detail

reset

public J3DVertexAccessor reset(javax.media.j3d.GeometryArray ga,
                      boolean... enableComponent)

Reset this accessor so that the subsequent call to J3DVertexAccessor.next() reads the first valid vertex in ga.

Overrides:

reset in class J3DVertexAccessor

Parameters:

ga - the geometry, or null to clear the previous internal reference

enableComponent - list or array of booleans enabling access to vertex components, iff present in ga, in order texCoord, color, normal, coord. If less than four booleans are provided the latter ones are assumed true.

Returns:

a reference to this J3DVertexAccessor

reset

public J3DVertexAccessor reset(JOGLGeometry jg,
                      boolean... enableComponent)

similar to J3DVertexAccessor.reset(GeometryArray, boolean...)

Overrides:

reset in class J3DVertexAccessor

resetImpl

protected J3DVertexAccessor resetImpl()

Common impl of reset(GeometryArray, boolean...) and reset(JOGLGeometry, boolean...).

read

public J3DVertexAccessor read()

Access the vertex storage and read the enabled vertex components at J3DVertexAccessor.componentIndex.

Note: if the internal indices for the access are outside the legal bounds for the vertex storage then the underlying access method will throw an exception according to the storage type.

Specified by:

read in class J3DVertexAccessor

write

public J3DVertexAccessor write()

Access the vertex storage and write the enabled vertex components.

Note: if the internal indices for the access are outside the legal bounds for the vertex storage then the underlying access method will throw an exception according to the storage type.

Specified by:

write in class J3DVertexAccessor

checkFormat

public boolean checkFormat(javax.media.j3d.GeometryArray ga)

Check if the class, storage type, and vertex format of ga is compatible with this accessor implementation.

Specified by:

checkFormat in class J3DVertexAccessor

checkFormat

public boolean checkFormat(JOGLGeometry jg)

this impl returns true

Overrides:

checkFormat in class J3DVertexAccessor

newInstance

public J3DVertexAccessor newInstance()

make a new instance of this accessor implementation

Specified by:

newInstance in class J3DVertexAccessor
