EmbeddedCacheManagerCommandDispatcher

public EmbeddedCacheManagerCommandDispatcher(CommandDispatcher<M,C> dispatcher,
 Function<CacheContainerGroupMember, M> unwrapper,
 Function<M, CacheContainerGroupMember> wrapper)

Creates a command dispatcher decorator.

Parameters:

dispatcher - the decorated command dispatcher

unwrapper - a function that converts a cache container group member to the member type expected by the decorated command dispatcher

wrapper - a function that converts a cache container group member from the member type expected by the decorated command dispatcher

Method Details

getContext

public C getContext()

Description copied from interface: CommandDispatcher

Returns the context with which this dispatcher was created.

Specified by:

getContext in interface CommandDispatcher<A extends Comparable<A>, M extends GroupMember<A>>

Returns:

a command execution context

dispatchToMember

public <R, E extends Exception> CompletionStage<R> dispatchToMember(Command<R, ? super C, E> command,
 CacheContainerGroupMember member)
                                                             throws IOException

Description copied from interface: CommandDispatcher

Executes the specified command on the specified group member. If the member has no corresponding dispatcher, the returned completion stage throws a CancellationException.

Specified by:

dispatchToMember in interface CommandDispatcher<A extends Comparable<A>, M extends GroupMember<A>>

Type Parameters:

R - the command execution return type

E - the command exception type

Parameters:

command - the command to execute

member - the group member on which to execute the command

Returns:

the future result of the command execution

Throws:

IOException - if the command could not be sent

dispatchToGroup

public <R, E extends Exception>
Map<CacheContainerGroupMember, CompletionStage<R>> dispatchToGroup(Command<R, ? super C, E> command)
                                                            throws IOException

Description copied from interface: CommandDispatcher

Executes the specified command on all members of the group, optionally excluding some members. If a given member has no corresponding dispatcher, its completion stage throws a CancellationException.

Specified by:

dispatchToGroup in interface CommandDispatcher<A extends Comparable<A>, M extends GroupMember<A>>

Type Parameters:

R - the command execution return type

E - the command exception type

Parameters:

command - the command to execute

Returns:

a completion stage per member of the group on which the command was executed

Throws:

IOException - if the command could not be sent

dispatchToGroup

public <R, E extends Exception>
Map<CacheContainerGroupMember, CompletionStage<R>> dispatchToGroup(Command<R, ? super C, E> command,
 Set<CacheContainerGroupMember> excluding)
                                                            throws IOException
