Method Detail

view

public F view((F,G) pair)

Description copied from interface: Lens

Extracts a value of the input field type from the input object type.

This method is analogous to a "getter" in traditional object-oriented programming.

Specified by:

view in interface Lens<(F,G)::F,(F2,G)::F2>

Parameters:

pair - A value of the input object type.

Returns:

The extracted value of the input field type.

update

public (F2,G) update(F2 newValue,
                     (F,G) pair)

Description copied from interface: Lens

Combines a value of the output field type with a value of the input object type to produce a combined value of the output object type.

This method is analogous to a "setter" in traditional object-oriented programming. Note that the given field b does not necessarily have to correspond with the straightforward transformation from the input object to the output object.

Specified by:

update in interface Lens<(F,G)::F,(F2,G)::F2>

Parameters:

newValue - A value of the output field type with which to update the output object.

pair - A value of the input object type to be converted to a value of the output object type.

Returns:

A value of the output object type, with the output field updated with the given value.

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
