+--ucar.multiarray.ConcreteIndexMap.ZZMap
- Enclosing class:
- ConcreteIndexMap
- protected class ConcreteIndexMap.ZZMap
- extends java.lang.Object
An Map of int by int key. (Z is the math symbol for integers).
A Map maps keys to values.
A Map cannot contain duplicate keys;
each key can map to at most one value.
For this implementation, the keys are restricted to non-negative
integers, and we only use non-negative integers as values.
A ZZMap is like a readonly 1-d array of int.
The size() method returns the array length.
The get(int ii) method returns the int stored at
position ii;
This class also supports a functional composition framework via
the setPrev() method. The implementation of get(int) and size()
provided here is simply the identity composed with whatever.
Subclasses will override this functionality.

protected ConcreteIndexMap.ZZMap(ConcreteIndexMap.ZZMap prev)
- Construct a ZZMap form the functional composition
of the new Map with another.
rebind(int [] range) calls prev.rebind(range),
get(int key) is composed as get(prev.get(key))
- Parameters:
prev - ZZMap this is composed with.
