This implementation returns a fixed value for a method. Other than the org.easymock.bytebuddy.implementation.StubMethod implementation, this implementation allows to determine a specific value which must be assignable to the returning value of any instrumented method. Otherwise, an exception will be thrown.

Nested and Inner Type Summary

Modifier and Type	Class and Description
public static interface	FixedValue.AssignerConfigurable Represents a fixed value implementation that is using a default assigner for attempting to assign the fixed value to the return type of the instrumented method.
protected static class	FixedValue.ForArgument A fixed value implementation that returns a method's argument.
protected static class	FixedValue.ForConstantValue A fixed value implementation that represents its fixed value as a constant pool value or a byte code instruction.
protected static enum	FixedValue.ForNullValue A fixed value of `null`.
protected static class	FixedValue.ForOriginType A fixed value that appends the origin type of the instrumented type.
protected static class	FixedValue.ForThisValue A fixed value of `this`.
protected static class	FixedValue.ForValue A fixed value implementation that represents its fixed value as a static field of the instrumented class.

Field Summary

Modifier and Type	Field and Description
protected final Assigner	assigner The assigner that is used for assigning the fixed value to a method's return type.
protected final Assigner.Typing	typing Indicates if dynamic type castings should be attempted for incompatible assignments.
