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
Modifier and TypeMethodDescriptionReturn an array ofProperyDescriptors
for the properties currently defined in this DynaClass.getDynaProperty
(String name) Return a property descriptor for the specified property, if it exists; otherwise, returnnull
.getName()
Return the name of this DynaClass (analogous to thegetName()
method ofjava.lang.Classinvalid input: '<'/code), which allows the same
DynaClass
implementation class to support different dynamic classes, with different sets of properties.Instantiate and return a new DynaBean instance, associated with this DynaClass.

Method Details
-
getName
String getName()Return the name of this DynaClass (analogous to thegetName()
method ofjava.lang.Classinvalid input: '<'/code), which allows the same
DynaClass
implementation class to support different dynamic classes, with different sets of properties.- Returns:
- the name of the DynaClass
-
getDynaProperty
Return a property descriptor for the specified property, if it exists; otherwise, returnnull
.- 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
-
getDynaProperties
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
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 accessibleInstantiationException
- if this Class represents an abstract class, an array class, a primitive type, or void; or if instantiation fails for some other reason
