Interface DynaClass

All Known Subinterfaces:
  MutableDynaClass

All Known Implementing Classes:
  BasicDynaClass, org.apache.commons.beanutils.JDBCDynaClass, RowSetDynaClass, WrapDynaClass, ResultSetDynaClass

public interface DynaClass

A DynaClass is a simulation of the functionality of `java.lang.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
`DynaProperty[]` | `getDynaProperties()` Return an array of `ProperyDescriptors` for the properties currently defined in this DynaClass.
`DynaProperty` | `getDynaProperty(java.lang.String name)` Return a property descriptor for the specified property, if it exists; otherwise, return `null`.
`java.lang.String` | `getName()` Return the name of this DynaClass (analogous to the `getName()` method of `java.lang.ClassDynaClass` implementation class to support different dynamic classes, with different sets of properties.
`DynaBean` | `newInstance()` Instantiate and return a new DynaBean instance, associated with this DynaClass.

Method Detail

### getName

    public java.lang.String getName()

  Return the name of this DynaClass (analogous to the `getName()` method of `java.lang.ClassDynaClass` implementation class to support different dynamic classes, with different sets of properties.
  Returns:
    the name of the DynaClass

### getDynaProperty

    public DynaProperty getDynaProperty(java.lang.String name)

  Return 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:
    `java.lang.IllegalArgumentException` - if no property name is specified

### getDynaProperties

    public DynaProperty[] getDynaProperties()

  Return an array of `ProperyDescriptors` 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

### newInstance

    public DynaBean newInstance()
                         throws java.lang.IllegalAccessException,
                                java.lang.InstantiationException

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