WithImplicitFieldType

protected WithImplicitFieldType(MethodDescription bootstrapMethod,
                                List<?> handleArguments,
                                InvokeDynamic.InvocationProvider invocationProvider,
                                InvokeDynamic.TerminationHandler terminationHandler,
                                Assigner assigner,

                                Object value)

Creates a new invoke dynamic instance with an implicit field type for the provided value.

Parameters:

bootstrapMethod - The bootstrap method.

handleArguments - The arguments that are provided to the bootstrap method.

invocationProvider - The target provided that identifies the method to be bootstrapped.

terminationHandler - A handler that handles the method return.

assigner - The assigner to be used.

dynamicallyTyped - true if the assigner should attempt dynamically-typed assignments.

value - The value that is supplied as the next argument to the bootstrapped method.

Method Detail

as

public InvokeDynamic as(Class<?> type)

Defines the given value to be treated as an instance of the provided type.

Parameters:

type - The type as which the provided instance should be handed to the bootstrap method.

Returns:

An invoke dynamic instance with the same configuration as this instance but with the provided argument appended to the arguments of the bootstrapped method.

as

public InvokeDynamic as(TypeDescription typeDescription)

Defines the given value to be treated as an instance of the provided type.

Parameters:

typeDescription - The type as which the provided instance should be handed to the bootstrap method.

Returns:

An invoke dynamic instance with the same configuration as this instance but with the provided argument appended to the arguments of the bootstrapped method.

materialize

protected InvokeDynamic materialize()

Description copied from class: InvokeDynamic.AbstractDelegator

Resolves the current configuration into a fully initialized invoke dynamic instance.

Specified by:

materialize in class InvokeDynamic.AbstractDelegator

Returns:

The fully resolved invoke dynamic instance.

withAssigner

public InvokeDynamic withAssigner(Assigner assigner,
                                  boolean dynamicallyTyped)

Description copied from class: InvokeDynamic

Instructs this implementation to use the provided assigner and decides if the assigner should apply dynamic typing.

Overrides:

withAssigner in class InvokeDynamic

Parameters:

assigner - The assigner to use.

dynamicallyTyped - true if the assigner should attempt dynamic typing.

Returns:

The invoke dynamic instruction where the given assigner and dynamic-typing directive are applied.

andThen

public Implementation andThen(Implementation implementation)

Description copied from class: InvokeDynamic

Applies this invoke dynamic implementation and removes the return value of the bootstrapped method from the operand stack before applying the provided implementation.

Overrides:

andThen in class InvokeDynamic

Parameters:

implementation - The implementation to apply after executing the dynamic method invocation.

Returns:

An implementation that first applies this implementation and then the provided one.

prepare

public InstrumentedType prepare(InstrumentedType instrumentedType)

Description copied from interface: Implementation

During the preparation phase of an implementation, implementations are eligible to adding fields or methods to the currently instrumented type. All methods that are added by this implementation are required to be implemented by the ByteCodeAppender that is emitted on the call to Implementation.appender(Implementation.Target) call. On this method call, loaded type initializers can also be added to the instrumented type.

Specified by:

prepare in interface Implementation

Overrides:

prepare in class InvokeDynamic

Parameters:

instrumentedType - The instrumented type that is the basis of the ongoing instrumentation.

Returns:

The instrumented type with any applied changes, if any.

appender

public ByteCodeAppender appender(Implementation.Target implementationTarget)

Description copied from interface: Implementation

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

Specified by:

appender in interface Implementation

Overrides:

appender in class InvokeDynamic

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 Implementation.prepare(InstrumentedType).

getInvocationProvider

protected InvokeDynamic.InvocationProvider getInvocationProvider()

Description copied from class: InvokeDynamic

Returns the invocation provider to be used for equals and hash code calculations.

Overrides:

getInvocationProvider in class InvokeDynamic

Returns:

The invocation provider that represents this instance.

toString

public String toString()

Overrides:

toString in class InvokeDynamic
