CellSpliterator

private CellSpliterator(CellSpliterator<T,C> o)

Method Details

jumpBefore

private void jumpBefore(long i)

cellUpdated

private void cellUpdated()

tryAdvance

public boolean tryAdvance(Consumer<? super T> action)

Specified by:

tryAdvance in interface Spliterator<T extends NativeType<T>>

forEachRemaining

public void forEachRemaining(Consumer<? super T> action)

Specified by:

forEachRemaining in interface Spliterator<T extends NativeType<T>>

forEachRemainingInCell

private void forEachRemainingInCell(Consumer<? super T> action)

globalIndex

private long globalIndex(long cell,
 int index)

trySplit

public CellSpliterator<T,C> trySplit()

Specified by:

trySplit in interface LocalizableSpliterator<T extends NativeType<T>>

Specified by:

trySplit in interface RealLocalizableSpliterator<T extends NativeType<T>>

Specified by:

trySplit in interface Spliterator<T extends NativeType<T>>

estimateSize

public long estimateSize()

Specified by:

estimateSize in interface Spliterator<T extends NativeType<T>>

characteristics

public int characteristics()

Specified by:

characteristics in interface Spliterator<T extends NativeType<T>>

copy

public CellSpliterator<T,C> copy()

Specified by:

copy in interface LocalizableSpliterator<T extends NativeType<T>>

Specified by:

copy in interface RealLocalizableSpliterator<T extends NativeType<T>>

Specified by:

copy in interface Sampler<T extends NativeType<T>>

Returns:

- A new Sampler in the same state accessing the same values. It does NOT copy T, just the state of the Sampler. Otherwise use T.copy() if available. Sampler.copy().get() == Sampler.get(), i.e. both hold the same value, not necessarily the same instance (this is the case for an ArrayCursor for example)

get

public T get()

Description copied from interface: Sampler

Access the actual T instance providing access to a pixel, sub-pixel or integral region value the Sampler points at.

Specified by:

get in interface Sampler<T extends NativeType<T>>

getType

public T getType()

Description copied from interface: Typed

Get an instance of T.

It should not be assumed that the returned T instance is an independent copy. In particular, repeated calls to getType() may return the same instance.

Specified by:

getType in interface Sampler<T extends NativeType<T>>

Specified by:

getType in interface Typed<T extends NativeType<T>>

Returns:

an instance of T

toString

public String toString()

Overrides:

toString in class Object

getLongPosition

public long getLongPosition(int d)

Description copied from interface: Localizable

Return the current position in a given dimension.

Specified by:

getLongPosition in interface Localizable

Parameters:

d - dimension

Returns:

dimension of current position

localize

public void localize(long[] pos)

Description copied from interface: Localizable

Write the current position into the passed array.

Specified by:

localize in interface Localizable

Parameters:

pos - receives current position, length must be ≥ EuclideanSpace.numDimensions()

numDimensions

public int numDimensions()

Description copied from interface: EuclideanSpace

Gets the space's number of dimensions.

Specified by:

numDimensions in interface EuclideanSpace

localize

public void localize(int[] pos)

Description copied from interface: Localizable

Write the current position into the passed array.

Specified by:

localize in interface Localizable

Parameters:

pos - receives current position, length must be ≥ EuclideanSpace.numDimensions()

localize

Description copied from interface: RealLocalizable

Write the current position into the passed array.

Specified by:

localize in interface RealLocalizable

Specified by:

localize in interface Localizable

Specified by:

localize in interface RealLocalizable

Parameters:

position - receives current position EuclideanSpace.numDimensions() must be ≥ EuclideanSpace.numDimensions()
