Method Detail

toStream

public void toStream(java.io.DataOutputStream dos)
              throws DnaSerializationException

Description copied from interface: Attribute

This method writes the attribute to the provided output stream.

Specified by:

toStream in interface Attribute

Parameters:

dos - The output stream

Throws:

DnaSerializationException - Errors while writing the attribute to the output stream

fromStream

public void fromStream(java.io.DataInputStream dis,
                       Dna dna,
                       int indexName,
                       int length)
                throws MissingDnaContainerException

Description copied from interface: Attribute

This method reads the data with which the attribute has to be initialized.

Specified by:

fromStream in interface Attribute

Parameters:

dis - The input stream

dna - The Dna instance this class belongs to

indexName - The value of the name index

length - The length of the attribute

Throws:

MissingDnaContainerException - There is no reference to the current Dna container

updateRefs

public void updateRefs(int offset)

Description copied from interface: Attribute

This method updates all the references pointing to constant pool table's entries this attributes holds.

Specified by:

updateRefs in interface Attribute

Specified by:

updateRefs in class GenericAttribute

Parameters:

offset - The offset

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

The clone() method will return a new instance whose reference to the containing Dna instance is set to null. It is up to you appropriately setting it to the correct value.

Specified by:

clone in interface Attribute

Overrides:

clone in class GenericAttribute

Throws:

java.lang.CloneNotSupportedException

getBytesCount

public int getBytesCount()
