private ArrayImgRangeCopier(ArrayImgRangeCopier<T> copier)

Method Details

newInstance

public ArrayImgRangeCopier<T> newInstance()

Description copied from interface: RangeCopier

Return a new independent instance of this RangeCopier. This is used for multi-threading. The new instance works on the same source image, but has independent internal state.

Specified by:

newInstance in interface RangeCopier<T>

Returns:

new independent instance of this RangeCopier

copy

public void copy(long[] srcPos,
 T dest,
 int[] size)

Copy the block starting at srcPos with the given size into the (appropriately sized) dest array.

This finds the src range lists for all dimensions and then calls copy(Object, int) to iterate all range combinations.

Specified by:

copy in interface RangeCopier<T>

Parameters:

srcPos - min coordinates of block to copy from src Img.

dest - destination array. Type is byte[], float[], etc, corresponding to the src Img's native type.

size - dimensions of block to copy from src Img.

copy

private void copy(T dest,
 int d)

Iterate the rangesPerDimension list for the given dimension d and recursively call itself for iterating dimension d-1.

Parameters:

dest - destination array. Type is byte[], float[], etc, corresponding to the src Img's native type.

d - current dimension. This method calls itself recursively with d-1 until d==0 is reached.

setupDestSize

private void setupDestSize(int[] size)

updateRange

private void updateRange(int d)

copyRanges

private void copyRanges(T dest)

Once we get here, setupDestSize(int[]) and updateRange(int) for all dimensions have been called, so the dsteps, doffsets, cdims, and lengths fields have been appropriately set up for the current Range combination.

copyRangesRecursively

private void copyRangesRecursively(T src,
 int srcPos,
 T dest,
 int destPos,
 int d)

fillRanges

void fillRanges(T dest,
 int dConst)

Once we get here, setupDestSize(int[]) and updateRange(int) for all dimensions have been called, so the dsteps, doffsets, cdims, and lengths fields have been appropriately set up for the current Range combination. Also cellAccess is positioned on the corresponding cell.

fillRangesRecursively

private void fillRangesRecursively(T dest,
 int destPos,
 int d,
 int dConst)
