Interface DynaClass

All Known Subinterfaces:
MutableDynaClass
All Known Implementing Classes:
BasicDynaClass, LazyDynaClass, LazyDynaMap, ResultSetDynaClass, RowSetDynaClass, WrapDynaClass
public interface DynaClass

A DynaClass is a simulation of the functionality of Class for classes implementing the DynaBean interface. DynaBean instances that share the same DynaClass all have the same set of available properties, along with any associated data types, read-only states, and write-only states.

  • Method Summary

    Modifier and Type
    Method
    Description
    DynaProperty[]
    getDynaProperties()
    Returns an array of PropertyDescriptor for the properties currently defined in this DynaClass.
    DynaProperty
    getDynaProperty(String name)
    Returns a property descriptor for the specified property, if it exists; otherwise, return null.
    String
    getName()
    Returns the name of this DynaClass (analogous to the getName() method of Class, which allows the same DynaClass implementation class to support different dynamic classes, with different sets of properties.
    DynaBean
    newInstance()
    Instantiates and return a new DynaBean instance, associated with this DynaClass.

  • Method Details

    • getDynaProperties

      DynaProperty[] getDynaProperties()

      Returns an array of PropertyDescriptor for the properties currently defined in this DynaClass. If no properties are defined, a zero-length array will be returned.

      FIXME - Should we really be implementing getBeanInfo() instead, which returns property descriptors and a bunch of other stuff?

      Returns:
      the set of properties for this DynaClass

    • getDynaProperty

      DynaProperty getDynaProperty(String name)
      Returns a property descriptor for the specified property, if it exists; otherwise, return null.
      Parameters:
      name - Name of the dynamic property for which a descriptor is requested
      Returns:
      The descriptor for the specified property
      Throws:
      IllegalArgumentException - if no property name is specified

    • getName

      String getName()
      Returns the name of this DynaClass (analogous to the getName() method of Class, which allows the same DynaClass implementation class to support different dynamic classes, with different sets of properties.
      Returns:
      the name of the DynaClass

    • newInstance

      DynaBean newInstance() throws IllegalAccessException, InstantiationException
      Instantiates and return a new DynaBean instance, associated with this DynaClass.
      Returns:
      A new DynaBean instance
      Throws:
      IllegalAccessException - if the Class or the appropriate constructor is not accessible
      InstantiationException - if this Class represents an abstract class, an array class, a primitive type, or void; or if instantiation fails for some other reason
