Method Detail

getSize

long getSize()

A random JIT Selector with Selector.isNeverEnding() true should return a size as if it would be able to return each distinct element only once, because the size can be used in SelectionProbabilityWeightFactory.

Returns:

the approximate number of elements generated by this Selector, always >= 0

Throws:

IllegalStateException - if Selector.isCountable() returns false, but not if only Selector.isNeverEnding() returns true
