readDataAsObject

public <T> T readDataAsObject()
                       throws IOException

Description copied from interface: ObjectDataInput

Reads to stored Data as an object instead of a Data instance. The reason this method exists is that in some cases 'Data' is stored on serialization, but on deserialization the actual object instance is needed. Getting access to the Data is easy by calling the ObjectDataInput.readData() method. But deserializing the Data to an object instance is impossible because there is no reference to the SerializationService.

Specified by:

readDataAsObject in interface ObjectDataInput

Returns:

the read Object

Throws:

IOException - if it reaches end of file before finish reading

readObject

public Object readObject(Class aClass)
                  throws IOException

Specified by:

readObject in interface ObjectDataInput

Parameters:

aClass - The type of the class to use when reading

Returns:

object array read

Throws:

IOException - if it reaches end of file before finish reading

readData

public Data readData()
              throws IOException

Specified by:

readData in interface ObjectDataInput

Returns:

data read

Throws:

IOException - if it reaches end of file before finish reading

getClassLoader

public ClassLoader getClassLoader()

Description copied from interface: ObjectDataInput

Returns class loader that internally used for objects

Specified by:

getClassLoader in interface ObjectDataInput

Returns:

classLoader

getByteOrder

public ByteOrder getByteOrder()

Specified by:

getByteOrder in interface ObjectDataInput

Returns:

ByteOrder BIG_ENDIAN or LITTLE_ENDIAN

setVersion

public void setVersion(Version version)

If the serializer supports versioning it may set the version to use for the serialization on this object.

Parameters:

version -

getVersion

public Version getVersion()

If the serializer supports versioning it may set the version to use for the serialization on this object. This method makes the version available for the user.

Specified by:

getVersion in interface VersionAware

Returns:

the version of Version.UNKNOWN if the version is unknown to the object.
