Method Summary

Modifier and Type	Method and Description
Nodes	filter(Predicate<Node> predicate)
int	getSize() Returns the number of Node instances contained in this Nodes object.
default boolean	hasSingleNode() Returns true when this Nodes object contains exactly on Node instance, otherwise false.
default Stream<String>	idStream() Returns a stream of the id's of the Node instances contained in this Nodes object.
Nodes	intersected(Nodes otherNodes) Returns a Nodes object with the intersection of this Nodes object and the otherNodes object, i.e.
default Node	singleNode() Returns the single Node object contained in this Nodes object or, throws an ExactlyOneNodeExpectedException when the Nodes object contains no Node or more than one Node.
default String	singleNodeId() Returns the id of the single Node object contained in this Nodes object or, throws an ExactlyOneNodeExpectedException when the Nodes object contains no Node or more than one Node.

Method Detail

getSize

int getSize()

Returns the number of Node instances contained in this Nodes object.

stream

Stream<Node> stream()

Returns a stream of the Node instances contained in this Nodes object.

hasSingleNode

default boolean hasSingleNode()

Returns true when this Nodes object contains exactly on Node instance, otherwise false.

singleNode

default Node singleNode()

Returns the single Node object contained in this Nodes object or, throws an ExactlyOneNodeExpectedException when the Nodes object contains no Node or more than one Node.

singleNodeId

default String singleNodeId()

Returns the id of the single Node object contained in this Nodes object or, throws an ExactlyOneNodeExpectedException when the Nodes object contains no Node or more than one Node.

idStream

default Stream<String> idStream()

Returns a stream of the id's of the Node instances contained in this Nodes object.

intersected

Nodes intersected(Nodes otherNodes)

Returns a Nodes object with the intersection of this Nodes object and the otherNodes object, i.e. with all Node instances that are in both.

This object and the otherNodes are not modified.

union

Nodes union(Nodes otherNodes)

Returns a Nodes object with the union of this Nodes object and the otherNodes object, i.e. with all Node instances that are either in this Nodes object or in the otherNodes or in both.

This object and the otherNodes are not modified.

filter

Nodes filter(Predicate<Node> predicate)
