Method Details

iterator

public Iterator<DifferenceNode> iterator()

Specified by:

iterator in interface Iterable<DifferenceNode>

visit

public <T> T visit(de.serra.so_dirty.difference.visit.DifferenceVisitor<T> visitor,
 DifferenceVisit<T> visit)

Description copied from interface: DifferenceNode

Visits the current node.

The children will be visited after this node has been visited.

The visiting of children can be prevented by calling DifferenceVisit.dontGoDeeper() usually from the visitor.

Specified by:

visit in interface DifferenceNode

Type Parameters:

T - The return type of the visit.

Parameters:

visitor - The visitor.

Description copied from interface: DifferenceNode

The relative path inside the object tree.

Specified by:

getName in interface DifferenceNode

Returns:

The path.

getTypes

public Set<DifferenceType> getTypes()

Description copied from interface: DifferenceNode

Describes in what way the current node changed. Returns an empty set if there are no changes.

Specified by:

getTypes in interface DifferenceNode

Returns:

The types of change if any.

getChildNullable

public @Nullable DifferenceNode getChildNullable(String name)

Description copied from interface: DifferenceNode

Gets a direct child node in the object tree.

Will return null if the child does not exist.

Specified by:

getChildNullable in interface DifferenceNode

Parameters:

name - The name of the child node.
