Interface DynaClass

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.

DynaPropertygetDynaProperty(String name)
Return a property descriptor for the specified property, if it exists; otherwise, return null.
StringgetName()
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.
DynaBeannewInstance()
Instantiate and return a new DynaBean instance, associated with this DynaClass.

Method Detail

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

getDynaProperty

public DynaProperty getDynaProperty(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: IllegalArgumentException if no property name is specified

getName

public 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

newInstance

public DynaBean newInstance()
Instantiate 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
