Constructor Detail

AttributeChangeMutation

public AttributeChangeMutation(ESModelMutatorUtil util)

Creates a new mutation with the specified util.

Parameters:

util - The model mutator util used for accessing the model to be mutated.

Method Detail

clone

public Mutation clone()

Mutations must follow the prototype pattern as org.eclipse.emf.emfstore.internal.modelmutator.api.ModelMutator will clone pre-configured mutations before they will be completed and applied. This allows clients to provide a specifically configured set mutations and start the mutation only from cloning and applying the set of pre-configured mutations.

Specified by:

clone in class Mutation

Returns:

A copy of this mutation with the same configuration.

See Also:

Mutation.clone()

apply

public void apply()
           throws ESMutationException

Applies this mutation and returns whether it succeeded in being applied.

Specified by:

apply in interface ESMutation

Specified by:

apply in class Mutation

Throws:

ESMutationException - thrown if the mutation failed.

See Also:

Mutation.apply()

setNewValue

public ESAttributeChangeMutation setNewValue(Object newValue)

Sets the value that should be used when changing the attribute.

Specified by:

setNewValue in interface ESAttributeChangeMutation

Parameters:

newValue - the value of the attribute

Returns:

this mutation

See Also:

ESAttributeChangeMutation.setNewValue(java.lang.Object)

setRandomChangeMode

public ESAttributeChangeMutation setRandomChangeMode(ESRandomChangeMode mode)

Sets the change mode for this attribute change.

Specified by:

setRandomChangeMode in interface ESAttributeChangeMutation

Parameters:

mode - the random change mode to be set

Returns:

this mutation

ESAttributeChangeMutation.setRandomChangeMode(org.eclipse.emf.emfstore.modelmutator.ESRandomChangeMode)
