Class GridInClosure2<E1,E2>

java.lang.Object
  org.gridgain.grid.lang.GridMetadataAwareAdapter
      org.gridgain.grid.lang.GridLambdaAdapter
          org.gridgain.grid.lang.GridInClosure2<E1,E2>

Type Parameters:

E1 - Type of the first free variable, i.e. the element the closure is called or closed on.

E2 - Type of the second free variable, i.e. the element the closure is called or closed on.

All Implemented Interfaces:

Serializable, Cloneable, GridMetadataAware, GridPeerDeployAware, GridLambda

Direct Known Subclasses:

CI2, GridInClosure2X

public abstract class GridInClosure2<E1,E2>
extends GridLambdaAdapter

Defines a convenient side-effect only closure, i.e. the closure that has void return type. Since Java 6 doesn't provide a language construct for first-class function the closures are implemented as interfaces.

Type Alias

To provide for more terse code you can use a typedef CI2 class or various factory methods in GridFunc class. Note, however, that since typedefs in Java rely on inheritance you should not use these type aliases in signatures.

Thread Safety

Note that this interface does not impose or assume any specific thread-safety by its implementations. Each implementation can elect what type of thread-safety it provides, if any.

Method Detail

apply

public abstract void apply(E1 e1,
                           E2 e2)

Closure body.

Parameters:

e1 - First bound free variable, i.e. the element the closure is called or closed on.

e2 - Second bound free variable, i.e. the element the closure is called or closed on.

curry

public GridInClosure<E2> curry(E1 e1)

Curries this closure with given value. When result closure is called it will be executed with given value.

Parameters:

e1 - Value to curry with.

Returns:

Curried or partially applied closure with given value.

curry

public GridAbsClosure curry(E1 e1,
                            E2 e2)

Curries this closure with given values. When result closure is called it will be executed with given values.

Parameters:

e1 - Value to curry with.

e2 - Value to curry with.

Returns:

Curried or partially applied closure with given values.

uncurry3

public <E3> GridInClosure3<E1,E2,E3> uncurry3()

Gets closure that ignores its third argument and executes the same way as this in-closure with first and second arguments.

Type Parameters:

E3 - Type of 3d argument that is ignored.

Returns:

Closure that ignores its third argument and executes the same way as this in-closure with first and second arguments.
