public Mappings.FiniteAbstractMapping()

Method Detail

iterator

public Iterator<IntPair> iterator()

Description copied from interface: Mapping

Returns an iterator over the elements in this mapping.

This method is optional; implementations may throw UnsupportedOperationException.

toString

public String toString()

Returns a string representation of this mapping.

For example, the mapping

source	0	1	2
target	-1	3	2

target	0	1	2	3
source	-1	-1	2	1

is represented by the string "[1:3, 2:2]".

This method relies upon the optional method iterator().

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
