Class DAEUtils.FloatBlockAccessor

java.lang.Object

vona.dae.util.DAEUtils.FloatBlockAccessor

Enclosing class:

DAEUtils

static class DAEUtils.FloatBlockAccessor
extends java.lang.Object

Access a FloatBuffer backing a COLLADA "float_array" according to the configuration of a COLLADA "accessor".

Field Summary

Fields

Modifier and Type	Field and Description
int	blockCount number of valid blocks in src
int	destBlockSize total words to read in a block due to pattern
int	globalOffset global offset in words in src
int	localBlockSize stride-localOffset-(final words to skip in block due to pattern).
int	localOffset initial words to skip in a block due to pattern
protected boolean[]	pattern read pattern within a block, length <= stride
protected java.nio.FloatBuffer	src (private duplicate of) the source buffer
int	stride block stride in words in src

Modifier and Type	Method and Description
int	blocksRemaining() Check how many valid blocks remain to be read.
DAEUtils.FloatBlockAccessor	copyBlock(java.nio.FloatBuffer dest) Relative read.
DAEUtils.FloatBlockAccessor	copyBlock(int blockIndex, java.nio.FloatBuffer dest) Absolute read: position src at globalOffset+blockIndex*stride, then copyBlock(FloatBuffer).
boolean	hasRemaining() Check if any valid blocks remain to be read.
DAEUtils.FloatBlockAccessor	rewind() Reset this accessor so that the next copyBlock(FloatBuffer) will read the first block.

Field Detail

src

protected final java.nio.FloatBuffer src

globalOffset

public final int globalOffset

global offset in words in src

stride

public final int stride

block stride in words in src

blockCount

public final int blockCount

number of valid blocks in src

pattern

protected final boolean[] pattern

read pattern within a block, length <= stride

localOffset

public final int localOffset

initial words to skip in a block due to pattern

localBlockSize

public final int localBlockSize

stride-localOffset-(final words to skip in block due to pattern).

destBlockSize

public final int destBlockSize

total words to read in a block due to pattern

                           int globalOffset,
                           int stride,

Method Detail

toString

public java.lang.String toString()

dump settings

Overrides:

toString in class java.lang.Object

rewind

public DAEUtils.FloatBlockAccessor rewind()

Reset this accessor so that the next copyBlock(FloatBuffer) will read the first block.

blocksRemaining

public int blocksRemaining()

Check how many valid blocks remain to be read.

hasRemaining

public boolean hasRemaining()

Check if any valid blocks remain to be read.

copyBlock

public DAEUtils.FloatBlockAccessor copyBlock(int blockIndex,
                                    java.nio.FloatBuffer dest)

Absolute read: position src at globalOffset+blockIndex*stride, then copyBlock(FloatBuffer).

copyBlock

public DAEUtils.FloatBlockAccessor copyBlock(java.nio.FloatBuffer dest)

Relative read.

Advances src by one block, but only writes destBlockSize words to dest.
