org.apache.commons.beanutils
Class DynaProperty  

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

All Implemented Interfaces:

java.io.Serializable

---

public class DynaProperty

extends java.lang.Object

implements java.io.Serializable

The metadata describing an individual property of a DynaBean.

The meta contains an optional content type property (getContentType() 55 ) for use by mapped and iterated properties. A mapped or iterated property may choose to indicate the type it expects. The DynaBean implementation may choose to enforce this type on its entries. Alternatively, an implementatin may choose to ignore this property. All keys for maps must be of type String so no meta data is needed for map keys.

Constructor Summary

DynaProperty(java.lang.String name)           Construct a property that accepts any data type.

DynaProperty(java.lang.String name, java.lang.Class type)           Construct a property of the specified data type.

DynaProperty(java.lang.String name, java.lang.Class type, java.lang.Class contentType)           Construct an indexed or mapped DynaProperty that supports (pseudo)-introspection of the content type.

 

Method Summary

java.lang.String	getName()           Get the name of this property.
java.lang.Class	getType()           Gets the Java class representing the data type of the underlying property values.
boolean	isIndexed()           Does this property represent an indexed value (ie an array or List)?
boolean	isMapped()           Does this property represent a mapped value (ie a Map)?
private  java.lang.Class	readAnyClass(java.io.ObjectInputStream in)           Reads a class using safe encoding to workaround java 1.3 serialization bug.
private  void	readObject(java.io.ObjectInputStream in)           Reads field values for this object safely.
java.lang.String	toString()           Return a String representation of this Object.
private  void	writeAnyClass(java.lang.Class clazz, java.io.ObjectOutputStream out)           Write a class using safe encoding to workaround java 1.3 serialization bug.

contentType

protected transient java.lang.Class contentType

The (optional) type of content elements for indexed DynaProperty

Constructor Detail

DynaProperty

public DynaProperty(java.lang.String name)

Construct a property that accepts any data type.

---

DynaProperty

public DynaProperty(java.lang.String name,
                    java.lang.Class type)

Construct a property of the specified data type.

---

DynaProperty

public DynaProperty(java.lang.String name,
                    java.lang.Class type,
                    java.lang.Class contentType)

Construct an indexed or mapped DynaProperty that supports (pseudo)-introspection of the content type.

Method Detail

getName

public java.lang.String getName()

Get the name of this property.

---

getType

public java.lang.Class getType()

Gets the Java class representing the data type of the underlying property values.

There are issues with serializing primitive class types on certain JVM versions (including java 1.3). Therefore, this field must not be serialized using the standard methods.

Please leave this field as transient

---

getContentType

public java.lang.Class getContentType()

Gets the (optional) type of the indexed content for DynaProperty's that support this feature.

There are issues with serializing primitive class types on certain JVM versions (including java 1.3). Therefore, this field must not be serialized using the standard methods.

---

isIndexed

public boolean isIndexed()

Does this property represent an indexed value (ie an array or List)?

---

isMapped

public boolean isMapped()

Does this property represent a mapped value (ie a Map)?

---

toString

public java.lang.String toString()

Return a String representation of this Object.

---

writeObject

private void writeObject(java.io.ObjectOutputStream out)
                  throws java.io.IOException

Writes this object safely. There are issues with serializing primitive class types on certain JVM versions (including java 1.3). This method provides a workaround.

---

writeAnyClass

private void writeAnyClass(java.lang.Class clazz,
                           java.io.ObjectOutputStream out)
                    throws java.io.IOException

Write a class using safe encoding to workaround java 1.3 serialization bug.

---

readObject

private void readObject(java.io.ObjectInputStream in)
                 throws java.io.IOException,
                        java.lang.ClassNotFoundException

Reads field values for this object safely. There are issues with serializing primitive class types on certain JVM versions (including java 1.3). This method provides a workaround.

---

readAnyClass

private java.lang.Class readAnyClass(java.io.ObjectInputStream in)
                              throws java.io.IOException,
                                     java.lang.ClassNotFoundException

Reads a class using safe encoding to workaround java 1.3 serialization bug.
