- All Implemented Interfaces:
    IInputKey

      public class EDataTypeInSlotsKey
      extends BaseEMFTypeKey<org.eclipse.emf.ecore.EDataType>

  Instance tuples are of form (x), where x is an instance of the given eDataType residing at an attribute slot of an eObject in the model.

  - ### Method Detail

    - #### getPrettyPrintableName

          public java.lang.String getPrettyPrintableName()

      Description copied from interface: `IInputKey`
      A user-friendly name that can be shown on screen for degug purposes, included in exceptions, etc.

    - #### getStringID

          public java.lang.String getStringID()

      Description copied from interface: `IInputKey`
      An internal string identifier that can be used to uniquely identify to input key (relevant for distributed applications).

    - #### getArity

          public int getArity()

      Description copied from interface: `IInputKey`
      The width of tuples in this relation.

    - #### isEnumerable

          public boolean isEnumerable()

      Description copied from interface: `IInputKey`
      Returns true iff instance tuples of the key can be enumerated.

      If false, the runtime can only test tuple membership in the extensional relation identified by the key, but not enumerate member tuples in general.
