public static final TypeInitializer.None INSTANCE

The singleton instance.

Method Detail

values

public static TypeInitializer.None[] 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 (TypeInitializer.None c : TypeInitializer.None.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TypeInitializer.None valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

isDefined

public boolean isDefined()

Indicates if this type initializer is defined.

Specified by:

isDefined in interface TypeInitializer

Returns:

true if this type initializer is defined.

expandWith

public TypeInitializer expandWith(ByteCodeAppender byteCodeAppenderFactory)

Expands this type initializer with another byte code appender. For this to be possible, this type initializer must be defined.

Specified by:

expandWith in interface TypeInitializer

Parameters:

byteCodeAppenderFactory - The byte code appender to apply as the type initializer.

Returns:

A defined type initializer.

wrap

public TypeWriter.MethodPool.Record wrap(TypeWriter.MethodPool.Record record)

Creates a method pool record that applies this type initializer while preserving the record that was supplied.

Specified by:

wrap in interface TypeInitializer

Parameters:

record - The record to wrap.

Returns:

A new record that represents the supplied record while also executing this type initializer.

apply

public ByteCodeAppender.Size apply(MethodVisitor methodVisitor,
                                   Implementation.Context implementationContext,
                                   MethodDescription instrumentedMethod)

Applies this byte code appender to a type creation process.

Specified by:

apply in interface ByteCodeAppender

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.
