Constructor Detail

AbstractClassTransformation

public AbstractClassTransformation()

Method Detail

dependentTransforms

public abstract java.lang.String[] dependentTransforms()

Description copied from interface: Transformation

Should return a list of the transformations that this transform requires before it can execute on a class. For the core Transformations this is equal to getClass().getSimpleName().

Specified by:

dependentTransforms in interface Transformation

Returns:

A list of transforms that must run first.

transform

public abstract void transform(javassist.CtClass clazz)
                        throws TransformationException

Description copied from interface: Transformation

Modifies the passed in CtClass based on the transformation necessary.

Specified by:

transform in interface Transformation

Parameters:

clazz - The CtClass to modify

Throws:

TransformationException - If an error occurs in the transformation process

equals

public boolean equals(java.lang.Object obj)

Description copied from interface: Transformation

Note that the equals check is not just about equality, but whether the transforms are equivalent. Any equivalent transforms, even if a different object should result in a true return.

Specified by:

equals in interface Transformation

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to check for equality.

Returns:

True if equal, false otherwise

See Also:

For the definition of equals, Which implements a default equals and hashcode

hashCode

public int hashCode()

Specified by:

hashCode in interface Transformation

Overrides:

hashCode in class java.lang.Object

Returns:

The hashcode

See Also:

Object.hashCode()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getTransformationName

public java.lang.String getTransformationName()

Description copied from interface: Transformation

When the dependencies for a Transformation are being determined it is this name which should be listed in the dependency list. The name can be anything but AbstractClassTransformation implements this as getClass().getSimpleName() which is used in many of the transformations.

Specified by:

getTransformationName in interface Transformation

Returns:

The name of the transformation used in dependency matching
