public enum StubMethod extends java.lang.Enum<StubMethod> implements Implementation.Composable, ByteCodeAppender
This implementation creates a method stub which does nothing but returning the default value of the return type of the method. These default values are:- The value
0
for all numeric type. - The null character for the
char
type. false
for theboolean
type.- Nothing for
void
types. - A
null
reference for any reference types. Note that this includes primitive wrapper types.

values
public static StubMethod[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (StubMethod c : StubMethod.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static StubMethod valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
-
prepare
public InstrumentedType prepare(InstrumentedType instrumentedType)
Prepares a given instrumented type.- Specified by:
prepare
in interfaceInstrumentedType.Prepareable
- Parameters:
instrumentedType
- The instrumented type in its current form.- Returns:
- The prepared instrumented type.
-
appender
public ByteCodeAppender appender(Implementation.Target implementationTarget)
Creates a byte code appender that determines the implementation of the instrumented type's methods.- Specified by:
appender
in interfaceImplementation
- 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
InstrumentedType.Prepareable.prepare(InstrumentedType)
.
-
andThen
public Implementation andThen(Implementation implementation)
Appends the supplied implementation to this implementation.- Specified by:
andThen
in interfaceImplementation.Composable
- Parameters:
implementation
- The subsequent implementation.- Returns:
- An implementation that combines this implementation with the provided one.
-
andThen
public Implementation.Composable andThen(Implementation.Composable implementation)
Appends the supplied composable implementation to this implementation.- Specified by:
andThen
in interfaceImplementation.Composable
- Parameters:
implementation
- The subsequent composable implementation.- Returns:
- A composable implementation that combines this implementation with the provided one.
-
apply
public ByteCodeAppender.Size apply(org.objectweb.asm.MethodVisitor methodVisitor, Implementation.Context implementationContext, MethodDescription instrumentedMethod)
Applies this byte code appender to a type creation process.- Specified by:
apply
in interfaceByteCodeAppender
- Parameters:
methodVisitor
- The method visitor to which the byte code appender writes its code to.implementationContext
- The implementation context of the current type creation process.instrumentedMethod
- The method that is the target of the instrumentation.- Returns:
- The required size for the applied byte code to run.
