Method Detail

getNumberOfExceptions

public int getNumberOfExceptions()

Description copied from interface: ExceptionsAttribute

Gets the number of exceptions that will be stored within the exception_index_table.

Specified by:

getNumberOfExceptions in interface ExceptionsAttribute

Returns:

int Dimension of the exception_index_table

setExceptionIndexTable

public void setExceptionIndexTable(java.util.List<java.lang.Integer> table)

getExceptionIndexTable

public java.util.List<java.lang.Integer> getExceptionIndexTable()

Description copied from interface: ExceptionsAttribute

Gets the exception_index_table. This data strucutre is actually a List containing indexes pointing to constant pool table entries of type CONSTANT_Class_info. These entries define the classes of the exceptions this method is declareced to throw

Specified by:

getExceptionIndexTable in interface ExceptionsAttribute

Returns:

List The exception_index_table

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
