public interface ArbitrarySupplier<T extends @Nullable Object>
extends Supplier<Arbitrary<T>>
Implementations of this class are used to provide single arbitraries for
ForAll
parameters and parameter types annotated with From
.
Use ForAll.supplier()
or From.supplier()
attributes to specify
the actual implementation class.
Either supplyFor(TypeUsage)
or get()
must be overridden.
But not both.

Method Details
-
supplyFor
Override this method if you need more information about the target type, e.g. annotations or type parameters.This method takes precedence if both
supplyFor(TypeUsage)
andget()
are overridden.- Parameters:
targetType
- Specifies the type to generate.- Returns:
- A new arbitrary instance
-
get
Override this method if generating the arbitrary is straightforward. This is probably the standard usage.Mind that
supplyFor(TypeUsage)
takes precedence if bothsupplyFor(TypeUsage)
andget()
are overridden.
