SourceFileAttribute

public SourceFileAttribute()

Creates a new instance of SourceFileAttribute

Method Detail

setSourceFileIndex

public void setSourceFileIndex(int srcFileIndex)

Description copied from interface: SourceFileAttribute

The value of the sourcefile_index item must be a valid index into the constant_pool table. The constant pool entry at that index must be a CONSTANT_Utf8_info structure representing a string.

Specified by:

setSourceFileIndex in interface SourceFileAttribute

Parameters:

srcFileIndex - A valid index into the constant pool table as described above

getSourceFileIndex

public int getSourceFileIndex()

Description copied from interface: SourceFileAttribute

The value of the sourcefile_index item must be a valid index into the constant_pool table. The constant pool entry at that index must be a CONSTANT_Utf8_info structure representing a string.

Specified by:

getSourceFileIndex in interface SourceFileAttribute

Returns:

int A valid index into the constant pool table as described above

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 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 - 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:

DnaDeserializationException - Errors while reading the attribute from the stream

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

innerValidations

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

Overrides:

innerValidations in class GenericAttribute

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 value.

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
