Interface DynaClass

Known Subinterfaces:
MutableDynaClass
Known Implementing Classes:
BasicDynaClass, JDBCDynaClass, LazyDynaClass, LazyDynaMap, ResultSetDynaClass, RowSetDynaClass, WrapDynaClass

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(String name)
Return a property descriptor for the specified property, if it exists; otherwise, return null.
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 Details

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

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()
            throws IllegalAccessException,
                   InstantiationException
Instantiate and return a new DynaBean instance, associated with this DynaClass.
Returns:
A new DynaBean instance
