Constructor Details

ForField

protected ForField(String fieldName,
 boolean cached,
 boolean privileged,
 boolean returning,
 Assigner assigner,
 FieldLocator.Factory fieldLocatorFactory)

Creates a new invocation handler adapter that loads its value from a field.

Parameters:

fieldName - The name of the field.

cached - Determines if the Method instances that are handed to the intercepted methods are cached in static fields.

privileged - Determines if the Method instances are retrieved by using an java.security.AccessController.

returning - Determines if this implementation is returning the result value or is dropping it.

assigner - The assigner to apply when defining this implementation.

fieldLocatorFactory - The field locator factory to use.

Method Details

withoutMethodCache

public InvocationHandlerAdapter.WithoutPrivilegeConfiguration withoutMethodCache()

Description copied from class: InvocationHandlerAdapter

By default, any Method instance that is handed over to an InvocationHandler is cached in a static field. By invoking this method, this feature can be disabled.

Specified by:

withoutMethodCache in class InvocationHandlerAdapter

Returns:

A similar invocation handler adapter that applies caching.

withAssigner

public Implementation.Composable withAssigner(Assigner assigner)

Description copied from class: InvocationHandlerAdapter

Configures an assigner to use with this invocation handler adapter.

Specified by:

withAssigner in interface InvocationHandlerAdapter.AssignerConfigurable

Specified by:

withAssigner in class InvocationHandlerAdapter

Parameters:

assigner - The assigner to apply when defining this implementation.

Returns:

This instrumentation with the given assigner configured.

withPrivilegedLookup

public InvocationHandlerAdapter.AssignerConfigurable withPrivilegedLookup()

Description copied from class: InvocationHandlerAdapter

Configures that the method constants supplied to the invocation handler adapter are resolved using an java.security.AccessController.

Specified by:

withPrivilegedLookup in interface InvocationHandlerAdapter.WithoutPrivilegeConfiguration

Specified by:

withPrivilegedLookup in class InvocationHandlerAdapter

Returns:

This instrumentation with a privileged lookup configured.

andThen

public Implementation andThen(Implementation implementation)

Appends the supplied implementation to this implementation.

Specified by:

andThen in interface Implementation.Composable

Parameters:

implementation - The subsequent implementation.

Returns:

An implementation that combines this implementation with the provided one.

andThen

public Implementation.Composable andThen(Implementation.Composable implementation)

Appends the supplied composable implementation to this implementation.

Specified by:

andThen in interface Implementation.Composable

Parameters:

implementation - The subsequent composable implementation.

Returns:

A composable implementation that combines this implementation with the provided one.

prepare

public InstrumentedType prepare(InstrumentedType instrumentedType)

Prepares a given instrumented type.

Specified by:

prepare in interface InstrumentedType.Prepareable

Parameters:

instrumentedType - The instrumented type in its current form.

Returns:

The prepared instrumented type.

appender

public ByteCodeAppender appender(Implementation.Target implementationTarget)

Creates a byte code appender that determines the implementation of the instrumented type's methods.

Specified by:

appender in interface Implementation

Parameters:

implementationTarget - The target of the current implementation.

Returns:

A byte code appender for implementing methods delegated to this implementation. This byte code appender is also responsible for handling methods that were added by this implementation on the call to InstrumentedType.Prepareable.prepare(InstrumentedType).
