Constructor Detail

ValueTypeMarshaler

public ValueTypeMarshaler()

Construct a ValueTypeMarshaler, which can marshal any type.

ValueTypeMarshaler

public ValueTypeMarshaler(Class javaType)

Construct a ValueTypeMarshaler, which prefers to marshal javaType. The marshaler can still marshall other objects, but will perform better with javaType. The bean properties are marshaled first and then the public fields in the order they are returned by the java.lang.reflect.Fields getFields method.

Parameters:

javaType - The preferred Java type.

ValueTypeMarshaler

public ValueTypeMarshaler(Class javaType,
                          PropertyDescriptor[] propDescs,
                          Field[] fields)

Construct a ValueTypeMarshaler, which prefers to marshal javaType. The marshaler can still marshall other objects, but will perform better with javaType.

Parameters:

javaType - The preferred Java type.

propDescs - The bean properties in the order they will be marshaled.

fields - The fields in the order they will be marshaled.

Method Detail

getMechanismType

public String getMechanismType()

Get the serializer's mechanism type. Not used by jBroker Web.

Specified by:

getMechanismType in interface Serializer

Returns:

string with mechanism type

getAttributes

public Attribute[] getAttributes(Object obj)

Get the element attributes

Specified by:

getAttributes in interface Serializer

Parameters:

obj - the object that is being serialized

Returns:

an array of attributes for the serialzied object

serialize

public void serialize(OutputStream os,
                      Object obj)
               throws IOException

Serialize the given bean object to the given output stream

Specified by:

serialize in interface Serializer

Parameters:

os - the portable output stream

obj - the object to write

Throws:

IOException - if an I/O exception occurred during write

deserialize

public Object deserialize(InputStream is,
                          Class javaType)
                   throws IOException

Initialize the given bean object from the given input stream

Specified by:

deserialize in interface Deserializer

Parameters:

is - the input stream to read object from

javaType - the expected Java type

Returns:

a newly created object initialized from stream

Throws:

IOException - if an I/O exception occurred duing read

isJAXRPCValueType

public static boolean isJAXRPCValueType(Class type)

returns true if the type is a JAX-RPC value type.

getTypeMap

public static TypeMap getTypeMap(Class javaType)

returns the java to xml TypeMap for the parameter type
