ArbitrarySupplier (documentation 1.7.1 API)

All Superinterfaces:

java.util.function.Supplier<Arbitrary<T>>

@API(status=MAINTAINED,
     since="1.7.0")
public interface ArbitrarySupplier<T>
extends java.util.function.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 Summary

All Methods Instance Methods Default Methods
Modifier and Type	Method	Description
`default @Nullable Arbitrary<T>`	`get()`	Override this method if generating the arbitrary is straightforward.
`default @Nullable Arbitrary<T>`	`supplyFor(TypeUsage targetType)`	Override this method if you need more information about the target type, e.g. annotations or type parameters.

- Method Detail
  - supplyFor
```
@Nullable
default @Nullable Arbitrary<T> supplyFor(TypeUsage targetType)
```
    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) and get() are overridden.
    
    Parameters:
    
    targetType - Specifies the type to generate.
    
    Returns:
    
    A new arbitrary instance
  - get
```
@Nullable
default @Nullable Arbitrary<T> get()
```
    Override this method if generating the arbitrary is straightforward. This is probably the standard usage.
    Mind that supplyFor(TypeUsage) takes precedence if both supplyFor(TypeUsage) and get() are overridden.
    
    Specified by:
    
    get in interface java.util.function.Supplier<T>
    
    Returns:
    
    A new arbitrary instance
