Method Details

getLeft

final L getLeft()

Overrides:

getLeft in class Either<L,R>

isLeft

public boolean isLeft()

Description copied from class: Either

Returns true if this either is a left, false otherwise.

Specified by:

isLeft in class Either<L,R>

Returns:

true if this either is a left, false otherwise.

isRight

public boolean isRight()

Description copied from class: Either

Returns true if this either is a right, false otherwise.

Specified by:

isRight in class Either<L,R>

Returns:

true if this either is a right, false otherwise.

swap

public Either<R,L> swap()

Description copied from class: Either

If this is a left, then return the left value in right, or vice versa.

Specified by:

swap in class Either<L,R>

Returns:

an Either that is a Left if this is a Right or a Right if this is a Left. The value remains the same.

fold

public <V> V fold(Function<? super L, V> ifLeft,
 Function<? super R, V> ifRight)

Description copied from class: Either

Applies the function to the wrapped value, applying ifLeft if this is a Left and ifRight if this is a Right.

Specified by:

fold in class Either<L,R>

Type Parameters:

V - the destination type

Parameters:

ifLeft - the function to apply if this is a Left

ifRight - the function to apply if this is a Right

Returns:

the result of the applies function

bimap

public <LL,RR> Either<LL,RR> bimap(Function<? super L, ? extends LL> ifLeft,
 Function<? super R, ? extends RR> ifRight)

Description copied from class: Either

Map the given functions across the appropriate side.

Specified by:

bimap in class Either<L,R>

Type Parameters:

LL - the LHS type

RR - the RHS type

Parameters:

ifLeft - The function to map if this Either is a left.

ifRight - The function to map if this Either is a right.

Returns:

A new either value after mapping with the appropriate function applied.

equals
