Constructor Detail

DecimateMap

public DecimateMap(int position,
                   boolean[] pattern)

Create an ConcreteIndexMap which decimates along a specific dimension. Using this in an MultiArrayProxy will result in the the length of dimension position appearing smaller. The values which will show through are selected by the pattern argument.

Parameters:

position - the dimension number to clip along

pattern - index values along the dimension will show through where pattern is set to true. If pattern.length is less than the source dimension length, the pattern is repeated.

DecimateMap

public DecimateMap(ConcreteIndexMap prev,
                   int position,
                   boolean[] pattern)

Create an ConcreteIndexMap which decimates along a specific dimension. Using this in an MultiArrayProxy will result in the the length of dimension position appearing smaller. The values which will show through are selected by the pattern argument.

Parameters:

prev - ConcreteIndexMap to be composed with this.

position - the dimension number to clip along

pattern - index values along the dimension will show through where pattern is set to true. If pattern.length is less than the source dimension length, the pattern is repeated.
