Parameters:

infoBean - BeanInfo for a bean containing this property

clzType - the type of the property

sName - the property name

sXml - the XML tag name

xml - additional XML information

Method Detail

isCloneRequired

public boolean isCloneRequired()

Description copied from class: PropertyAdapter

Determine if the property value must be deep-cloned. Typically, a property value must be deep-cloned if it is a mutable reference type, e.g. StringBuffer, Date, byte[].

Specified by:

isCloneRequired in class PropertyAdapter

Returns:

true if the property value must be "deep" cloned when the containing object is cloned

fromXml

public Object fromXml(XmlElement xml)

Deserialize an object from an XML element.

Overrides:

fromXml in class PropertyAdapter

Parameters:

xml - the XML element to deserialize from

Returns:

the object deserialized from the XML element

toXml

public XmlElement toXml(Object o)

Serialize an object into an XML element.

Overrides:

toXml in class PropertyAdapter

Parameters:

o - the object to serialize

Returns:

the XML element representing the serialized form of the passed object

readExternal

public Object readExternal(DataInput in)
                    throws IOException

Read a value from the passed DataInput object.

Overrides:

readExternal in class PropertyAdapter

Parameters:

in - the DataInput stream to read property data from

Returns:

the data read from the DataInput; never null

Throws:

IOException - if an I/O exception occurs

writeExternal

public void writeExternal(DataOutput out,
                          Object o)
                   throws IOException

Write the specified data to the passed DataOutput object.

Overrides:

writeExternal in class PropertyAdapter

Parameters:

out - the DataOutput stream to write to

o - the data to write to the DataOutput; never null

Throws:

IOException - if an I/O exception occurs
