Method Detail

match

public ((K,?)|A) match((K,?) pair)

Description copied from interface: Prism

Attempts to extract the input field from the input object. Returns the straightforward transformation of the input object to the output object if the input field is not present.

For example, say that the input object type is DataResult and the output object type is Optional. Calling match with the data result will return either the value present in the result (if a DataResult is a success), or an absent Optional (if the result is an error).

Specified by:

match in interface Prism<(K,?)::A,(K,?)::B>

Parameters:

pair - A value of the input object type from which to attempt to extract the input field value.

Returns:

Either the value of the input field, or a value of the output object type equivalent to the input.

build

public (K,?) build(B b)

Description copied from interface: Prism

Constructs a value of the output object type with the given output field value.

For example, this may be used to construct an Optional or DataResult from a plain value.

Specified by:

build in interface Prism<(K,?)::A,(K,?)::B>

Parameters:

b - The value to construct the output object from.

Returns:

A value of the output object type that contains the output field.

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
