Interface PathEdge

All Superinterfaces:
Serializable
public interface PathEdge extends Serializable
Represents a directed edge in a Path Graph, which maps to a directed (Derived) Relation Type in the OM. For Relation Types, a direction must be specified.

  • Method Details

    • getType

      MetaResourceReference getType()
      Returns the type of the edge. This is a reference to a (Derived) Relation Type.
      Returns:
      the type of the edge

    • getDirection

      RelationTypeDirection getDirection()
      Returns the direction of the Relation Type. This is only relevant for Relation Types. Note : this is not the direction of the edge in the graph.
      Returns:
      the direction of the Relation Type

    • getRepetitionDepth

      int getRepetitionDepth()
      Returns the repetition depth, which indicates whether an edge is repeatable and to which depth. The value is 1 for an edge which is not repeatable. If the repetition depth is N > 1, the source and target types of the edge relation type must be compatible. The edge represents a subgraph consisting of N simple, parallel paths, with lengths 1, 2, ..., N, where the type and direction of every expanded edge are the same as the original edge.
      Returns:
      the repetition depth

    • getNodeName

      String getNodeName()
      Returns the name of the Path Node where the edge ends.
      Returns:
      the name of the Path Node where the edge ends

    • isSystem

      boolean isSystem()
      Check if this is a system part or not. System element cannot be removed by any user.
      Returns:
      True if this is a system part. False otherwise.
