FORWARD

public static final EdgeDirection.Forward FORWARD

Forward traversal direction. This represents a predicate traversal direction from the in-parameter to the out-parameter.

BACKWARD

public static final EdgeDirection.Backward BACKWARD

Backward traversal direction. This represents a predicate traversal direction from the out-parameter to the in-parameter.

UNDIRECTED

public static final EdgeDirection.Undirected UNDIRECTED

Arbitrary traversal direction. This represents an arbitrary predicate traversal direction, i.e., from the in-parameter to the out-parameter or from the out-parameter to the in-parameter.

BOTH

public static final EdgeDirection.Both BOTH

Arbitrary traversal direction. This represents an arbitrary predicate traversal direction, i.e., from the in-parameter to the out-parameter or from the out-parameter to the in-parameter.
