java.lang.Object
org.incenp.obofoundry.kgcl.SimpleLabelResolver
All Implemented Interfaces:
ILabelResolver
Direct Known Subclasses:
OntologyBasedLabelResolver
public class SimpleLabelResolver extends Object implements ILabelResolver
A basic implementation of the ILabelResolver interface.

This implementation is backed up by a simple dictionary mapping labels to their corresponding identifiers. When a new ID is requested (with getNewId(String)), it mints a temporary ID suitable for use with the AutoIDAllocator class.

    • resolve

      public String resolve(String label)
      Description copied from interface: ILabelResolver
      Finds the identifier corresponding to the given label.
      Specified by:
      resolve in interface ILabelResolver
      Parameters:
      label - The label to resolve.
      Returns:
      The identifier of the entity with the given label, or null if the label could not be resolved.

    • getNewId

      public String getNewId(String label)
      Description copied from interface: ILabelResolver
      Mints a new identifier for the given label.

      This method is used when a KGCL “create” instruction does not include an identifier for the node to be created (e.g., create class 'my new class'). It shall return a new identifier for the node to be created.

      Any subsequent call to ILabelResolver.resolve(String) with the same label shall return the same identifier.

      Specified by:
      getNewId in interface ILabelResolver
      Parameters:
      label - The label for which an identifier is requested.
      Returns:
      The newly minted identifier.

    • add

      public void add(String label, String identifier)
      Description copied from interface: ILabelResolver
      Registers a new label-to-identifier mapping.
      Specified by:
      add in interface ILabelResolver
      Parameters:
      label - The label to register.
      identifier - Its corresponding identifier.
