Class Choice

java.lang.Object

be.ac.umons.jsonschematools.generator.exploration.Choice

public class Choice
extends Object

The encoding of a choice made while exploring all the possibilities described by a schema. It uses a BitSet to store the current choice. If the choice is declared as exclusive (needed for oneOf, for instance), it is guaranteed that the bitset always has at most one set bit. If the choice is non-exclusive (needed for anyOf, for instance), the bitset can have more than one set bit. That is, if the choice is non-exclusive, it is possible to select multiple possibilities at the same time. It is possible to get the value in base 10 corresponding to the current choice.
