int	getHashCode() Returns a hash code to be used for the deduplicate map.
boolean	isIdentical(Object object) Determines if this instance is identical to another object.

Method Detail

getHashCode

int getHashCode()

Returns a hash code to be used for the deduplicate map. The returned hash code should be consitent wiwh isIdentical(Object), i.e. if two objects are identical they should have the same hash code.

Returns:

deduplication hash code

isIdentical

boolean isIdentical(Object object)

Determines if this instance is identical to another object.

Parameters:

object - the object to compare with this instance

Returns:

true if the two objects are identical and can be deduplicated
