Package org.openjdk.jmc.common.item

Interface IType<T>

Type Parameters:
T - class of the objects that the type is used for
All Superinterfaces:
IDescribable
All Known Implementing Classes:
ContentType, KindOfQuantity, LinearKindOfQuantity, RangeContentType, StructContentType
public interface IType<T> extends IDescribable
A type for objects of class T. They may have properties that can be accessed by using member accessors. If so, then items of the same type are expected to share the same behavior when accessed by accessors.

Analogous to Class in the Java type system.

  • Method Details

    • getAttributes

      @Deprecated List<IAttribute<?>> getAttributes()
      Deprecated.

    • getAccessorKeys

      Map<IAccessorKey<?>,? extends IDescribable> getAccessorKeys()
      Get keys for the accessors that this type knows of. Note that the returned accessors does not necessarily cover all possible data from the items of this type, and that it is always possible to define additional accessors that get or calculate values from the items in non-standard ways.

      Should only be used for low level type inspection. Iterators etc. should use a collection of predefined attributes.

      Returns:
      keys for the accessors defined for this type

    • hasAttribute

      boolean hasAttribute(ICanonicalAccessorFactory<?> attribute)
      Tell if attribute can return an accessor for this type. This method is semantically equivalent to attribute.getAccessor(type) != null, but may be cheaper.
      Parameters:
      attribute - attribute to check
      Returns:
      true if the attribute can return an accessor for this type, false if not

    • getAccessor

      <M> IMemberAccessor<M,T> getAccessor(IAccessorKey<M> attribute)
      Internal low-level mechanism for retrieving a member accessor for a type, or null if not available.

      This is only intended to be used by implementors of IAccessorFactory. All other usage should be replaced with ICanonicalAccessorFactory.getAccessor(IType) call to pre-defined accessors.

      Type Parameters:
      M - accessor value type
      Parameters:
      attribute - the identifier for the field
      Returns:
      a member accessor

    • getIdentifier

      String getIdentifier()
      String identifying the type. It must never be localized and it should only contain characters that are safe to use in various configuration files, e.g. in XML.
      Returns:
      type identifier
