Class Implementation.Context.Disabled

java.lang.Object

net.bytebuddy.implementation.Implementation.Context.ExtractableView.AbstractBase

net.bytebuddy.implementation.Implementation.Context.Disabled

All Implemented Interfaces:

Implementation.Context, Implementation.Context.ExtractableView

Enclosing interface:

Implementation.Context

public static class Implementation.Context.Disabled
extends Implementation.Context.ExtractableView.AbstractBase

An implementation context that does not allow for any injections into the static initializer block. This can be useful when redefining a class when it is not allowed to add methods to a class what is an implicit requirement when copying the static initializer block into another method.

Constructor Detail

Disabled

protected Disabled(TypeDescription instrumentedType,
                   ClassFileVersion classFileVersion)

Creates a new disabled implementation context.

Parameters:

instrumentedType - The instrumented type.

classFileVersion - The class file version to create the class in.

Method Detail

getAuxiliaryTypes

public List<DynamicType> getAuxiliaryTypes()

Description copied from interface: Implementation.Context.ExtractableView

Returns any AuxiliaryType that was registered with this Implementation.Context.

Returns:

A list of all manifested registered auxiliary types.

drain

public void drain(TypeInitializer.Drain drain,
                  ClassVisitor classVisitor,
                  AnnotationValueFilter.Factory annotationValueFilterFactory)

Description copied from interface: Implementation.Context.ExtractableView

Writes any information that was registered with an Implementation.Context to the provided class visitor. This contains any fields for value caching, any accessor method and it writes the type initializer. The type initializer must therefore never be written manually.

Parameters:

drain - The drain to write the type initializer to.

classVisitor - The class visitor to which the extractable view is to be written.

annotationValueFilterFactory - The annotation value filter factory to apply when writing annotation.

register

public TypeDescription register(AuxiliaryType auxiliaryType)

Description copied from interface: Implementation.Context

Registers an auxiliary type as required for the current implementation. Registering a type will cause the creation of this type even if this type is not effectively used for the current implementation.

Parameters:

auxiliaryType - The auxiliary type that is required for the current implementation.

Returns:

A description of the registered auxiliary type.

cache

public FieldDescription.InDefinedShape cache(StackManipulation fieldValue,
                                             TypeDescription fieldType)

Description copied from interface: Implementation.Context

Caches a single value by storing it in form of a private, final and static field. By caching values, expensive instance creations can be avoided and object identity can be preserved. The field is initiated in a generated class's static initializer.

Parameters:

fieldValue - A stack manipulation for creating the value that is to be cached in a static field. After executing the stack manipulation, exactly one value must be put onto the operand stack which is assignable to the given fieldType.

fieldType - The type of the field for storing the cached value. This field's type determines the value that is put onto the operand stack by this method's returned stack manipulation.

Returns:

A description of a field that was defined on the instrumented type which contains the given value.

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
