Package org.infinispan.commands

package org.infinispan.commands
Commands that operate on the cache, either locally or remotely. This package contains the entire command object model including interfaces and abstract classes. Your starting point is probably ReplicableCommand, which represents a command that can be used in RPC calls.

A sub-interface, VisitableCommand, represents commands that can be visited using the visitor pattern. Most commands that relate to public

invalid reference 
Cache
API methods tend to be VisitableCommands, and hence the importance of this interface.

The Visitor interface is capable of visiting VisitableCommands, and a useful abstract implementation of Visitor is

invalid reference 
org.infinispan.interceptors.base.CommandInterceptor
, which allows you to create interceptors that intercept command invocations adding aspects of behavior to a given invocation.

  • Class
    Description
    AbstractFlagAffectedCommand
    Base class for those commands that can carry flags.
    AbstractTopologyAffectedCommand
    Base class for commands that carry topology id.
    AbstractVisitor
    An abstract implementation of a Visitor that delegates all visit calls to a default handler which can be overridden.
    CommandInvocationId
    Represents an unique identified for non-transaction write commands.
    CommandsFactory
    A factory to build commands, initializing and injecting dependencies accordingly.
    CommandsFactoryImpl
     
    DataCommand
    Commands of this type manipulate data in the cache.
    FlagAffectedCommand
    Flags modify behavior of command such as whether or not to invoke certain commands remotely, check cache store etc.
    GlobalRpcCommand
    Commands correspond to specific areas of functionality in the cluster, and can be replicated using the GlobalInboundInvocationHandler.
    InitializableCommand
    Deprecated, for removal: This API element is subject to removal in a future version.
    since 11.0, please implement
    invalid reference 
    ReplicableCommand#invokeAsync(ComponentRegistry)
    instead
    LocalCommand
    This is a marker interface to indicate that such commands will never be replicated and hence will not return any valid command IDs.
    MetadataAwareCommand
    A command that contains metadata information.
    RemoteCommandsFactory
    Specifically used to create un-initialized ReplicableCommands from a byte stream.
    ReplicableCommand
    The core of the command-based cache framework.
    SegmentSpecificCommand
    Interface to be implemented when the command can define a single segment for its operation.
    TopologyAffectedCommand
    Some of the commands sent over the wire can only be honored by the receiver if the topology of the cluster at delivery time is still 'compatible' with the topology in place at send time (eg.
    TracedCommand
     
    VisitableCommand
    A type of command that can accept Visitors, such as DDAsyncInterceptor.
