Interface SeededVariableAmount<T>

Type Parameters:

T - The seed object type

All Known Implementing Classes:

SeededVariableAmount.WrappedVariableAmount

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface SeededVariableAmount<T>

Represents a value which may vary depending on a seed object.

Nested Class Summary

Nested Classes

Modifier and Type	Interface	Description
static final class	SeededVariableAmount.WrappedVariableAmount<T>	A SeededVariableAmount which wraps another VariableAmount and defers all operations to the inner VariableAmount without the seed.

Method Summary

Modifier and Type	Method	Description
double	amount(RandomGenerator rand, T seed)	Gets an instance of the variable amount depending on the given random object and the seed object.
static <T> SeededVariableAmount<T>	fixed(double value)	Creates a new 'fixed' variable amount, calls to amount(java.util.random.RandomGenerator, T) will always return the fixed value.
default int	flooredAmount(RandomGenerator rand, T seed)	Gets the amount as if from amount(RandomGenerator, Object) but floored to the nearest integer equivalent.
static <T> SeededVariableAmount<T>	wrapped(VariableAmount value)	Creates a new variable amount wrapping the given VariableAmount, calls to amount(java.util.random.RandomGenerator, T) will always return wrapped amounts value.

Method Details

fixed

static <T> SeededVariableAmount<T> fixed(double value)

Creates a new 'fixed' variable amount, calls to amount(java.util.random.RandomGenerator, T) will always return the fixed value.

Type Parameters:

T - The seed object type

Parameters:

value - The fixed value

Returns:

A variable amount representation

wrapped

static <T> SeededVariableAmount<T> wrapped(VariableAmount value)

Creates a new variable amount wrapping the given VariableAmount, calls to amount(java.util.random.RandomGenerator, T) will always return wrapped amounts value.

Type Parameters:

T - The seed object type

Parameters:

value - The wrapped variable amount

Returns:

A variable amount representation

amount

double amount(RandomGenerator rand,
 T seed)

Gets an instance of the variable amount depending on the given random object and the seed object.

Parameters:

rand - The random object

seed - The seed object

Returns:

The amount

flooredAmount

default int flooredAmount(RandomGenerator rand,
 T seed)

Gets the amount as if from amount(RandomGenerator, Object) but floored to the nearest integer equivalent.

Parameters:

rand - The random object

seed - The seed object

Returns:

The floored amount
