Member Function Documentation

final boolean equals

(

Object

o

)

Method used to compare two ERXMultiKeys. A multi key is equal to another multi key if the number of keys are equal and all of the keys are either both null or equals.

Parameters:

o

object to be compared

Returns:

result of comparison

final int hashCode

(

)

Calculates a unique hash code for the given array of keys.

Returns:

unique hash code for the array of keys.

final Object [] keys

(

)

Method used to return the object array of keys for the current multi-key.
DO NOT MODIFY!

Returns:

object array of keys

final void recomputeHashCode

(

)

Recomputes the hash code if you ever changes the keys array directly

String toString

(

)

String representation of the multi-key.

Returns:

string representation of key.
