Method Detail

getCurrentValue

public java.lang.String getCurrentValue(java.lang.String substr)
                                 throws RvTestException

Returns the value of the current element in this set corresponding to the given substitution string.

Parameters:

substr - the substitution string

Returns:

the current element value as string

Throws:

RvTestException

changeValue

public boolean changeValue()

Changes the current value. The choice of the new element can be by any criteria implemented by the subclasses. The return value is used as an indication to the calling code that this set has exhausted its current range of values. This is especially helpful for an outer loop to detect the end of loop condition for an inner loop. For large random sets relying on this value may not be efficient, so it should avoided.

Returns:

true, if all the unique values have been exhausted and the current value is a duplicate
