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.

Method Detail

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.
