Method Detail

getTargetClass

public java.lang.Class getTargetClass()

Description copied from interface: Primitive

Return the class that is modified by this primitive.

Specified by:

getTargetClass in interface Primitive

Returns:

A java Class object.

updateVersion

protected void updateVersion()

Increases the version number and updates the cached code to a new version. These changes are done for all of the classes in the inheritance tree of the modified class, so, all of the tree evolves to a new version.

updateVersion

protected void updateVersion(java.lang.Class<?> clazz,
                             java.lang.String superclassName)
                      throws StructuralIntercessionException

Updates the class and subclasses provided

Parameters:

clazz - The class to evolve

superclassName - The new superclass

Throws:

StructuralIntercessionException

undoUpdateVersion

protected void undoUpdateVersion()

Reverts all changes done by updateVersion

changeVersion

protected java.lang.String changeVersion(java.lang.String content,
                                         java.lang.Class<?> clazz,
                                         int from,
                                         int to)

Changes the version of the class in the source code.

Parameters:

content - The source code

clazz - The original class

from - Actual version number of the source code

to - New version number

Returns:

Source code updated

getSuperClass

protected java.lang.Class<?> getSuperClass(ClassContent classContent)
                                    throws StructuralIntercessionException

Throws:

StructuralIntercessionException

undo

public void undo()
          throws StructuralIntercessionException

Reverts all changes

Specified by:

undo in interface Primitive

Throws:

StructuralIntercessionException

execute

public java.util.Set<ClassContent> execute()
                                    throws StructuralIntercessionException

Do changes in the class and update the version number

Specified by:

execute in interface Primitive

Returns:

A set of ClassContent modified by the primitive

Throws:

StructuralIntercessionException - If there are errors while performing the modificactions

executePrimitive

protected abstract void executePrimitive()
                                  throws StructuralIntercessionException

Method that each primitive have to override to implement its own funtionality.

Throws:

StructuralIntercessionException - If there are any error

undoPrimitive

protected abstract void undoPrimitive()
                               throws StructuralIntercessionException

Method that each primitive have to override to revert its own changes over the ClassContent.

Throws:

StructuralIntercessionException - If there are any error

isSafe

public boolean isSafe()

Returns if the primitive is safe or not. If it isn't safe, the PrimitiveExecutor hace to send all clases to recompile for type error detection

Specified by:

isSafe in interface Primitive

Returns:

false, if the application needs to recompile, true otherwise
