GeomNioFloatData

public GeomNioFloatData(int maxElements,
                        int elemSize,
                        int stride,
                        boolean reversed)

GeomNioFloatData

public GeomNioFloatData(int maxElements,
                        int elemSize,
                        boolean reversed)

Method Detail

setBuffer

public final void setBuffer(java.nio.FloatBuffer buffer)

Sets the NIO float buffer underlying this. If the underlying format is not a float buffer then it will be converted.

getBuffer

public final java.nio.FloatBuffer getBuffer()

Returns:

the NIO float buffer underlying this. If the underlying format is not a float buffer then it will be converted.

getData

public final float[] getData()

Returns:

an array with all the floats assigned in the last draw cycle. In some implementations this might return a copy, so only use if you have to. The data should not be changed once it is retrieved and should be considered read only.

getData

public final void getData(float[] outBuffer)

Gets an array with all the floats assigned in the last draw cycle. In some implementations this might return a copy, so only use if you have to. The data should not be changed once it is retrieved and should be considered read only.

Parameters:

buffer - the buffer array to write values to (must be of sufficient size)

getData

public final void getData(int index,
                          long elemOffset,
                          float[] outBuffer,
                          int start,
                          int length)

Gets an array with all the floats assigned in the last draw cycle. In some implementations this might return a copy, so only use if you have to. The data should not be changed once it is retrieved and should be considered read only.

Parameters:

index -

elemOffset -

outBuffer - the buffer array to write values to (must be of sufficient size)

start -

length -

start

public final void start()

Resets the buffer to zero and prepares to receive data from the various set() calls. In some implementations this will destroy data.

Overrides:

start in class GeomData

end

public final void end()

Locks the data and sets the size()

set

public final void set(float[] a,
                      int start,
                      int length)

Special optimized way to set a bulk amount of floats right into the data, starting at the index specified.

Parameters:

a -

start -

length -
