Class AbstractDimensionlessBlockProcessor<I,O>

java.lang.Object

net.imglib2.algorithm.blocks.AbstractDimensionlessBlockProcessor<I,O>

Type Parameters:

I - input primitive array type, e.g., float[]

O - output primitive array type, e.g., float[]

All Implemented Interfaces:

BlockProcessor<I,O>

public abstract class AbstractDimensionlessBlockProcessor<I,O>
extends Object
implements BlockProcessor<I,O>

Boilerplate for BlockProcessor to simplify implementations.

This is intented as a base class for BlockProcessor with an adaptable number of dimensions (such as converters). For BlockProcessor with a fixed number of source dimensions, see AbstractBlockProcessor.

getSourcePos(), getSourceSize(), and getSourceInterval() are implemented to return the protected fields long[] sourcePos and int[] sourceSize}. The protected} method int sourceLength()} can be used to get the number of elements in the source interval.

getSourceBuffer() is implemented according to the sourcePrimitiveType specified at construction.

Method Detail

setTargetInterval

public void setTargetInterval(Interval interval)

Specified by:

setTargetInterval in interface BlockProcessor<I,O>

updateNumSourceDimsensions

protected boolean updateNumSourceDimsensions(int n)

Re-allocates sourcePos and sourceSize arrays if they do not already exist and have length==n.

Parameters:

n - new number of source dimensions

Returns:

true if sourcePos and sourceSize arrays were re-allocated

sourceLength

protected int sourceLength()

getSourcePos

public long[] getSourcePos()

Specified by:

getSourcePos in interface BlockProcessor<I,O>

getSourceSize

public int[] getSourceSize()

Specified by:

getSourceSize in interface BlockProcessor<I,O>

getSourceInterval

public Interval getSourceInterval()

Specified by:

getSourceInterval in interface BlockProcessor<I,O>

getSourceBuffer

public I getSourceBuffer()

Description copied from interface: BlockProcessor

Get a src array of sufficient size.

Consecutive calls may return the same array, but don't have to.

Specified by:

getSourceBuffer in interface BlockProcessor<I,O>
