org.infinispan.cache.impl.InvocationHelper

All Implemented Interfaces:

TransactionResourceConverter

public class InvocationHelper
extends Object
implements TransactionResourceConverter

It invokes the VisitableCommand through this cache AsyncInterceptorChain.

It creates injected transactions and auto commits them, if the cache is transactional.

InvocationHelper

public InvocationHelper()

Method Details

invoke

public <T> T invoke(VisitableCommand command,
 int keyCount)

Same as invoke(ContextBuilder, VisitableCommand, int) but using the default ContextBuilder.

Type Parameters:

T - The return type.

Parameters:

command - The VisitableCommand to invoke.

keyCount - The number of keys affected by the command.

Returns:

The invocation result.

invoke

public <T> T invoke(ContextBuilder builder,
 VisitableCommand command,
 int keyCount)

Same as invoke(InvocationContext, VisitableCommand) but using builder to build the InvocationContext to use.

Type Parameters:

T - The return type.

Parameters:

builder - The ContextBuilder to create the InvocationContext to use.

command - The VisitableCommand to invoke.

keyCount - The number of keys affected by the command.

Returns:

The invocation result.

invoke

public <T> T invoke(InvocationContext context,
 VisitableCommand command)

Invokes the command using context.

This method blocks until the command finishes. Use invokeAsync(InvocationContext, VisitableCommand) for non-blocking.

Type Parameters:

T - The return type.

Parameters:

context - The InvocationContext to use.

command - The VisitableCommand to invoke.

Returns:

The invocation result.

invokeAsync

public <T> CompletableFuture<T> invokeAsync(VisitableCommand command,
 int keyCount)

Same as invoke(ContextBuilder, VisitableCommand, int) but using the default ContextBuilder.

Type Parameters:

T - The return type.

Parameters:

command - The VisitableCommand to invoke.

keyCount - The number of keys affected by the command.

Returns:

A CompletableFuture with the result.

invokeAsync

public <T> CompletableFuture<T> invokeAsync(ContextBuilder builder,
 VisitableCommand command,
 int keyCount)

Same as invoke(InvocationContext, VisitableCommand) but using the InvocationContext created by builder.

Type Parameters:

T - The return type.

Parameters:

builder - The ContextBuilder to create the InvocationContext to use.

command - The VisitableCommand to invoke.

keyCount - The number of keys affected by the command.

Returns:

A CompletableFuture with the result.

invokeAsync

public <T> CompletableFuture<T> invokeAsync(InvocationContext context,
 VisitableCommand command)

Invokes the command using context and returns a CompletableFuture.

The CompletableFuture is completed with the return value of the invocation.

Type Parameters:

T - The return type.

Parameters:

context - The InvocationContext to use.

command - The VisitableCommand to invoke.

Returns:

A CompletableFuture with the result.

createInvocationContextWithImplicitTransaction

public InvocationContext createInvocationContextWithImplicitTransaction(int keyCount,
 boolean forceCreateTransaction)

Creates an invocation context with an implicit transaction if it is required. An implicit transaction is created if there is no current transaction and autoCommit is enabled.

Parameters:

keyCount - how many keys are expected to be changed

Returns:

the invocation context

toString

public String toString()

Overrides:

toString in class Object

convertSynchronization

public AsyncSynchronization convertSynchronization(javax.transaction.Synchronization synchronization)

Specified by:

convertSynchronization in interface TransactionResourceConverter

Parameters:

synchronization - The Synchronization to convert.

Returns:

An AsyncSynchronization instance of synchronization.

convertXaResource

public AsyncXaResource convertXaResource(XAResource resource)

Specified by:

convertXaResource in interface TransactionResourceConverter

Parameters:

resource - The XAResource to convert.

Returns:

An AsyncXaResource instance of resource.
