Constructor Detail

ForStaticField

protected ForStaticField(Object fixedValue,
                         Assigner assigner,
                         boolean dynamicallyTyped)

Creates a new static field fixed value instrumentation with a random name for the field containing the fixed value.

Parameters:

fixedValue - The fixed value to be returned.

assigner - The assigner to use for assigning the fixed value to the return type of the instrumented value.

dynamicallyTyped - If true, the runtime type of the given value will be considered for assigning the return type.

ForStaticField

protected ForStaticField(String fieldName,
                         Object fixedValue,
                         Assigner assigner,
                         boolean dynamicallyTyped)

Creates a new static field fixed value instrumentation.

Parameters:

fieldName - The name of the field for storing the fixed value.

fixedValue - The fixed value to be returned.

assigner - The assigner to use for assigning the fixed value to the return type of the instrumented value.

dynamicallyTyped - If true, the runtime type of the given value will be considered for assigning the return type.

Method Detail

withAssigner

public Instrumentation withAssigner(Assigner assigner,
                                    boolean dynamicallyTyped)

Description copied from interface: FixedValue.AssignerConfigurable

Defines an explicit assigner to this fixed value instrumentation.

Specified by:

withAssigner in interface FixedValue.AssignerConfigurable

Parameters:

assigner - The assigner to use for assigning the fixed value to the return type of the instrumented value.

dynamicallyTyped - If true, the runtime type of the given value will be considered for assigning the return type.

Returns:

A fixed value instrumentation that makes use of the given assigner.

prepare

public InstrumentedType prepare(InstrumentedType instrumentedType)

Description copied from interface: Instrumentation

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

Specified by:

prepare in interface Instrumentation

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(Instrumentation.Target instrumentationTarget)

Description copied from interface: Instrumentation

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

Specified by:

appender in interface Instrumentation

Parameters:

instrumentationTarget - The target of the current instrumentation.

Returns:

A byte code appender for implementing methods delegated to this instrumentation. This byte code appender is also responsible for handling methods that were added by this instrumentation on the call to Instrumentation.prepare(net.bytebuddy.instrumentation.type.InstrumentedType).

equals

public boolean equals(Object other)

Overrides:

equals in class FixedValue

hashCode

public int hashCode()

Overrides:

hashCode in class FixedValue

toString

public String toString()

Overrides:

toString in class Object
