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 de-serializing the Data to an object instance is impossible because there is no reference to the SerializationService.

Specified by:

readDataAsObject in interface ObjectDataInput

Type Parameters:

T - type of the object to be read

Returns:

the read Object

Throws:

IOException - if it reaches end of file before finish reading

readObject

public <T> T readObject(Class aClass)
                 throws IOException

Specified by:

readObject in interface ObjectDataInput

Type Parameters:

T - type of the object to be read

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

getSerializationService

public InternalSerializationService getSerializationService()

Specified by:

getSerializationService in interface ObjectDataInput

Returns:

serialization service for this object

getByteOrder

public ByteOrder getByteOrder()

Specified by:

getByteOrder in interface ObjectDataInput

Returns:

ByteOrder BIG_ENDIAN or LITTLE_ENDIAN

getWanProtocolVersion

public Version getWanProtocolVersion()

Description copied from interface: WanProtocolVersionAware

Returns the WAN protocol version. This method is similar to VersionAware.getVersion() but is used in WAN replication, not in message exchange inside a single cluster.

Specified by:

getWanProtocolVersion in interface WanProtocolVersionAware

Returns:

the WAN protocol version or Version.UNKNOWN if not set

See Also:

VersionAware.getVersion()

setWanProtocolVersion

public void setWanProtocolVersion(Version version)

Description copied from interface: WanProtocolVersionAware

Sets the WAN protocol version. This method is similar to VersionAware.setVersion(Version) but is used in WAN replication, not in message exchange inside a single cluster.

Specified by:

setWanProtocolVersion in interface WanProtocolVersionAware

Parameters:

version - the WAN protocol version

See Also:

VersionAware.setVersion(Version)

getVersion

public Version getVersion()

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

Specified by:

getVersion in interface VersionAware

Returns:

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

setVersion

public void setVersion(Version version)

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

Specified by:

setVersion in interface VersionAware

Parameters:

version - version to set
