Method Detail

setValue

public void setValue(int value)

Description copied from interface: ConstantValueAttribute

This method sets the constantvalue_index of the current ConstantValueAttribute. The provided index has to be a valid index into the constant pool table. The entry at that index gives the constant value represented by this attribute.

Specified by:

setValue in interface ConstantValueAttribute

Parameters:

constantValueIndex -

getValue

public int getValue()

Description copied from interface: ConstantValueAttribute

This method gets the constantvalue_index of the current ConstantValueAttribute. This index will be a valid index into the constant pool table. The entry at that index gives the constant value represented by this attribute.

Specified by:

getValue in interface ConstantValueAttribute

Returns:

int

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 -

Throws:

DnaSerializationException

fromStream

public void fromStream(java.io.DataInputStream dis,
                       Dna dna,
                       int index,
                       int length)
                throws DnaDeserializationException,
                       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 -

dna -

index -

length -

Throws:

DnaDeserializationException

MissingDnaContainerException

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 -

innerValidations

protected void innerValidations(ConstantPoolTable cpt)
                         throws AttributeValidationException,
                                AttributeOutOfRangeException,
                                MissingDnaContainerException,
                                MissingCPTableException

Overrides:

innerValidations in class GenericAttribute

Parameters:

cpt -

Throws:

AttributeValidationException

AttributeOutOfRangeException

MissingDnaContainerException

MissingCPTableException

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 constantValueIndex.

Specified by:

clone in interface Attribute

Overrides:

clone in class GenericAttribute

Throws:

java.lang.CloneNotSupportedException

getBytesCount

public int getBytesCount()

Description copied from interface: BytesCountable

This method must return the overall number of bytes required by the component implementing this interface.

Specified by:

getBytesCount in interface BytesCountable
