Method Detail

getDiffStatus

public DiffStatus getDiffStatus()

Description copied from interface: DiffElement

Difference status of the element compared to original one.

Exception: for an original element DiffStatus has other meaning.

• DiffStatus.ORIGINAL shows that it is present in original data
• DiffStatus.ORIGINAL_ABSENT shows that it is absent in original data but exists in at least one comparing data

Other values are considered non valid.

Specified by:

getDiffStatus in interface DiffElement

Returns:

difference status

isHierarhyEqual

public boolean isHierarhyEqual()

Description copied from interface: DiffElement

Shows whether hierarchy of all children, regardless of their properties, are the same for compared and original elements.

Specified by:

isHierarhyEqual in interface DiffElement

Returns:

true if hierarchy of children are the same

isChildrenEqual

public boolean isChildrenEqual()

Description copied from interface: DiffElement

Shows whether hierarchy and properties of all children are the same for compared and original elements.

Specified by:

isChildrenEqual in interface DiffElement

Returns:

true if hierarchy and properties of children are completely the same

isSelfEqual

public boolean isSelfEqual()

Description copied from interface: DiffElement

Shows whether compared and original elements have the same properties. Ignores children elements.

Specified by:

isSelfEqual in interface DiffElement

Returns:

true if properties are the same

getProjection

public Projection getProjection()

Description copied from interface: DiffElement

Projection of the element.

In case if some comparing data has no such element it will return null.

Specified by:

getProjection in interface DiffElement

Returns:

reference on projection of element or null

asAdded

public void asAdded()

asRemoved

public void asRemoved()

asExists

public void asExists(boolean hierarhyEqual,
                     boolean childrenEqual,
                     boolean selfEqual)

asOriginal

public void asOriginal(boolean exists)
