Interface ILcdS57Relationship

All Known Implementing Classes:
TLcdS57Relationship
public interface ILcdS57Relationship
A bidirectional relationship between two S-57 feature objects.

A relationship always involves two participants and can be of three different types:

  • master
  • slave
  • peer

A relationship between a master and a slave can be modelled directly as a single, direct relationship between the master and the slave, or as two indirect relationships between a shared collection feature. Peer-to-peer relationships are always modelled via a shared collection feature. The figure below illustrates each of the relationship types.

S-57 relationship types.

    • getFirstObject

      ILcdS57FeatureObject getFirstObject()
      Returns the first of the two objects that are involved in this relationship.

      In case of a direct connection between a master and a slave, this will always be the master. In case of a indirect connection via a collection feature, this will always be the collection feature.

      Returns:
      the first of the two objects that are involved in this relationship.

    • getSecondObject

      ILcdS57FeatureObject getSecondObject()
      Returns the second of the two objects that are involved in this relationship.

      In case of a direct connection between a master and a slave, this will always be the slave. In case of a indirect connection via a collection feature, this will always be the object that is connected to the collection feature.

      Returns:
      the first of the two objects that are involved in this relationship.

    • getType

      int getType()
      Returns the type of this relationship. This can be one of
      • MASTER
      • SLAVE
      • PEER
      or another, product-specific type.
      Returns:
      the type of this relationship.

    • getComment

      String getComment()
      Returns the comment, associated with this relationship.
      Returns:
      the comment, associated with this relationship.
