Method Detail

isOldSet

boolean isOldSet()

Returns the value of the 'Old Set' attribute.

If the meaning of the 'Old Set' attribute isn't clear, there really should be more of a description here...

Returns:

the value of the 'Old Set' attribute.

See Also:

setOldSet(boolean), DeltaPackage.getChangeDelta_OldSet()

setOldSet

void setOldSet(boolean value)

Sets the value of the 'Old Set' attribute.

Parameters:

value - the new value of the 'Old Set' attribute.

See Also:

isOldSet()

isNewSet

boolean isNewSet()

Returns the value of the 'New Set' attribute.

If the meaning of the 'New Set' attribute isn't clear, there really should be more of a description here...

Returns:

the value of the 'New Set' attribute.

See Also:

setNewSet(boolean), DeltaPackage.getChangeDelta_NewSet()

setNewSet

void setNewSet(boolean value)

Sets the value of the 'New Set' attribute.

Parameters:

value - the new value of the 'New Set' attribute.

See Also:

isNewSet()

getListDeltas

org.eclipse.emf.common.util.EList getListDeltas()

Returns the value of the 'List Deltas' containment reference list. The list contents are of type ListDelta.

If the meaning of the 'List Deltas' reference list isn't clear, there really should be more of a description here...

Returns:

the value of the 'List Deltas' containment reference list.

See Also:

DeltaPackage.getChangeDelta_ListDeltas()

getSetChanged

boolean getSetChanged()

getChangeLocation

Location getChangeLocation()

Returns the location of the changed value.

Returns:

change location

getOldValue

java.lang.Object getOldValue()

Returns the old value.

Returns:

old value

getNewValue

java.lang.Object getNewValue()

Returns the new value.

Returns:

new value. New value may be affected by delta increments, typically resulting from the merge subsessions. Each commited subsession over the value of the structural feature will result in delta increments, where each new increment will be considered a new value of the delta

getNewValueBeforeIncrement

java.lang.Object getNewValueBeforeIncrement()

Returns:

- the original new value supplied by a contributor, disregarding delta increments (if any)

getChangedObject

java.lang.Object getChangedObject()

Returns the object that has been changed.

Returns:

changed object

getChangedObjectMatchingId

java.lang.String getChangedObjectMatchingId()

Returns the matching ID of the changed object.

Returns:

a matching ID

increments

int increments()

Returns:

- number of value increments created during local merge subsessions, 0 if none A delta increment is a change above the contributed delta, typically added during merge sub session. Each merge subsession after being commited will increment original delta with a new value. Delta increments can be traversed from the earliest to the latest same way unidirectional linked lists are traversed

increment

void increment(java.lang.Object newValue)

Parameters:

newValue - - add delta increment. Typically a result of merge subsession resulting in delta increment. Change increments chained one after another in a unidirectional linked list starting with original delta - change between a contributor and a base, and followed by delta increments after every subsession

decrement

java.lang.Object decrement()

decrement delta - remove last element from the linked list of delta increments

Returns:

- return delta decrement (the last link, or null if none)

override

java.lang.Object override(java.lang.Object value)

Overrides previous value. Do 1-step increment operation if no increments created

Parameters:

value -
