org.apache.commons.beanutils
Class BasicDynaClass  

java.lang.Object
  org.apache.commons.beanutils.BasicDynaClass

All Implemented Interfaces:

DynaClass, java.io.Serializable

Direct Known Subclasses:

LazyDynaClass

---

public class BasicDynaClass

extends java.lang.Object

implements DynaClass, java.io.Serializable

Minimal implementation of the DynaClass interface. Can be used as a convenience base class for more sophisticated implementations.

*

IMPLEMENTATION NOTE - The DynaBean implementation class supplied to our constructor MUST have a one-argument constructor of its own that accepts a DynaClass. This is used to associate the DynaBean instance with this DynaClass.

Field Detail

constructor

protected transient java.lang.reflect.Constructor constructor

The constructor of the dynaBeanClass that we will use for creating new instances.

---

constructorTypes

protected static java.lang.Class[] constructorTypes

The method signature of the constructor we will use to create new DynaBean instances.

---

constructorValues

protected java.lang.Object[] constructorValues

The argument values to be passed to the constructore we will use to create new DynaBean instances.

---

dynaBeanClass

protected java.lang.Class dynaBeanClass

The DynaBean implementation class we will use for creating new instances.

---

name

protected java.lang.String name

The "name" of this DynaBean class.

---

properties

protected DynaProperty[] properties

The set of dynamic properties that are part of this DynaClass.

---

propertiesMap

protected java.util.HashMap propertiesMap

The set of dynamic properties that are part of this DynaClass, keyed by the property name. Individual descriptor instances will be the same instances as those in the properties list.

Constructor Detail

BasicDynaClass

public BasicDynaClass()

Construct a new BasicDynaClass with default parameters.

---

BasicDynaClass

public BasicDynaClass(java.lang.String name,
                      java.lang.Class dynaBeanClass)

Construct a new BasicDynaClass with the specified parameters.

---

BasicDynaClass

public BasicDynaClass(java.lang.String name,
                      java.lang.Class dynaBeanClass,
                      DynaProperty[] properties)

Construct a new BasicDynaClass with the specified parameters.

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.

Specified by:

getName in interface DynaClass

---

getDynaProperty

public DynaProperty getDynaProperty(java.lang.String name)

Return a property descriptor for the specified property, if it exists; otherwise, return null.

Specified by:

getDynaProperty in interface DynaClass

---

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?

Specified by:

getDynaProperties in interface DynaClass

---

newInstance

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

Instantiate and return a new DynaBean instance, associated with this DynaClass.

Specified by:

newInstance in interface DynaClass

---

getDynaBeanClass

public java.lang.Class getDynaBeanClass()

Return the Class object we will use to create new instances in the newInstance() method. This Class MUST implement the DynaBean interface.

---

setDynaBeanClass

protected void setDynaBeanClass(java.lang.Class dynaBeanClass)

Set the Class object we will use to create new instances in the newInstance() method. This Class MUST implement the DynaBean interface.

---

setProperties

protected void setProperties(DynaProperty[] properties)

Set the list of dynamic properties supported by this DynaClass.
