Method Details

resolve

String resolve(String label)

Finds the identifier corresponding to the given label.

Parameters:

 String identifier)

Registers a new label-to-identifier mapping.

Parameters:

label - The label to register.

identifier - Its corresponding identifier.

getNewId

String getNewId(String label)

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.

Parameters:

label - The label for which an identifier is requested.

Returns:

The newly minted identifier.
