Method Details

copyFrom

public void copyFrom(OPhysicalPosition iSource)

toString

public String toString()

Overrides:

toString in class Object

fromStream

public OSerializableStream fromStream(byte[] iStream)
                               throws OSerializationException

Description copied from interface: OSerializableStream

Unmarshalls the object. Fills the current object with the values contained in the byte array representation restoring a previous state. Usually byte[] comes from the storage or network.

Specified by:

fromStream in interface OSerializableStream

Parameters:

iStream - byte array representation of the object

Returns:

The Object instance itself giving a "fluent interface". Useful to call multiple methods in chain.

Throws:

OSerializationException - if the unmarshalling does not succeed

toStream

public byte[] toStream()
                throws OSerializationException

Description copied from interface: OSerializableStream

Marshalls the object. Transforms the current object in byte[] form to being stored or transferred over the network.

Specified by:

toStream in interface OSerializableStream

Returns:

The byte array representation of the object

Throws:

OSerializationException - if the marshalling does not succeed

• OSerializableStream.fromStream(byte[])

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

Specified by:
