Description copied from class: Generator

Produces a value for a property parameter.

A generator may raise an unchecked exception if some condition exists which would lead to a confusing generation -- for example, if a generator honored a "range" configuration, and the endpoints were transposed.

Specified by:

generate in class Generator<Enum>

Parameters:

random - source of randomness to be used when generating the value

status - an object that the generator can use to influence the value it produces. For example, a generator for lists can use the size method to generate lists with a given number of elements.

Returns:

the generated value

canShrink

public boolean canShrink(Object larger)

Description copied from class: Generator

Tells whether this generator is allowed to participate in the Shrink process for the given "larger" value.

Unless overridden, the only criterion for whether a generator is allowed to participate in shrinking a value is if the value can be safely cast to the type of values the generator produces.

Overrides:

canShrink in class Generator<Enum>

Parameters:

larger - the "larger" value

Returns:

whether this generator can participate in "shrinking" the larger value
