Package org.anchoranalysis.image.io.stack.output.generator

Class RasterGeneratorBridge<T,V>

Object

RasterGenerator<T>

RasterGeneratorSelectFormat<T>

RasterGeneratorDelegateToRaster<V,T>

RasterGeneratorBridge<T,V>

Type Parameters:

T - exposed-iterator type

V - delegate-iterator-type (hidden type)

All Implemented Interfaces:

Generator<T>, TransformingGenerator<T,Stack>, ElementWriter<T>

public class RasterGeneratorBridge<T,V>
extends RasterGeneratorDelegateToRaster<V,T>

Allows us to call an RasterGenerator<S> as if it was an RasterGenerator<T> using an function to connect the two.

Constructor Details

RasterGeneratorBridge

public RasterGeneratorBridge(RasterGenerator<V> delegate,
 CheckedFunction<T,V,? extends Throwable> elementBridge)

Creates with a delegate and a function to bridge the exposed element-type to the delegate element-type.

Parameters:

delegate - the delegate RasterGenerator which is called after bridging.

elementBridge - the function that bridges the exposed element-type to the delegate element-type.

Method Details

transform

public Stack transform(T element)
                throws OutputWriteFailedException

Description copied from interface: TransformingGenerator

Applies any necessary preprocessing to create an element suitable for writing to the filesystem.

Specified by:

transform in interface TransformingGenerator<T,V>

Overrides:

transform in class RasterGeneratorDelegateToRaster<V,T>

Parameters:

element - element to be assigned and then transformed.

Returns:

the transformed element after necessary preprocessing.

Throws:

OutputWriteFailedException - if anything goes wrong.

convertBeforeAssign

protected V convertBeforeAssign(T element)
                         throws OperationFailedException

Description copied from class: RasterGeneratorDelegateToRaster

Converts an element before setting it on the delegate.

Specified by:

convertBeforeAssign in class RasterGeneratorDelegateToRaster<V,T>

Parameters:

element - element to convert

Returns:

converted element

Throws:

OperationFailedException - if anything goes wrong during conversion

convertBeforeTransform

protected Stack convertBeforeTransform(Stack stack)

Description copied from class: RasterGeneratorDelegateToRaster

Converts an element before calling RasterGeneratorDelegateToRaster.transform(T) on the delegate.

Specified by:

convertBeforeTransform in class RasterGeneratorDelegateToRaster<V,T>

Parameters:

stack - stack to convert

Returns:

converted element
