Constructor Detail

ForDynamicInvocation

protected ForDynamicInvocation(MethodDescription.InDefinedShape bootstrapMethod,
                               MethodDescription.SignatureToken signatureToken,
                               Advice.BootstrapArgumentResolver resolver)

Creates a delegator for a dynamic method invocation.

Parameters:

bootstrapMethod - The bootstrap method.

signatureToken - The advice method's signature token.

resolver - A resolver to provide the arguments to the bootstrap method.

Method Detail

of

protected static Advice.Delegator.Factory of(MethodDescription.InDefinedShape bootstrapMethod,
                                             Advice.BootstrapArgumentResolver.Factory resolverFactory,
                                             TypeDescription.Generic.Visitor<? extends TypeDescription.Generic> visitor)

Creates a new dynamic invocation delegator.

Parameters:

bootstrapMethod - The bootstrap method or constructor.

resolverFactory - A resolver factory to provide the arguments to the bootstrap method.

visitor - A visitor to apply to the parameter types prior to resolving the MethodType that is passed to the bootstrap method. The supplied types might not be available to the instrumented type what might make it necessary to camouflage them to avoid class loading errors. The actual type should then rather be passed in a different format by the supplied Advice.BootstrapArgumentResolver.

Returns:

An appropriate delegator.

apply

public StackManipulation apply(TypeDescription instrumentedType,
                               MethodDescription instrumentedMethod)

Materializes an invocation.

Specified by:

apply in interface Advice.Delegator

Parameters:

instrumentedType - The instrumented type.

instrumentedMethod - The instrumented method.

Returns:

An appropriate stack manipulation which needs to consume all arguments for the advice method and needs to provide a compatible return type.

getTypeToken

public MethodDescription.TypeToken getTypeToken()

Returns the advice method's type token.

Specified by:

getTypeToken in interface Advice.Delegator

Returns:

The advice method's type token.

assertVisibility

public void assertVisibility(TypeDescription instrumentedType)

Asserts the visibility of the delegation target.

Specified by:

assertVisibility in interface Advice.Delegator

Parameters:

instrumentedType - The instrumented type.
