InnerClasses

public InnerClasses()
Creates a new instance of InnerClasses

Method Detail

getNumberOfClasses

public int getNumberOfClasses()
Description copied from interface: InnerClassesAttribute
The number_of_classes defines how many entries are stored into the classes array. This data structure can be provided via the setClasses method shaped as a List.

Specified by:
getNumberOfClasses in interface InnerClassesAttribute
Returns:
int The number of entries of the classes array

setClasses

public void setClasses(java.util.List<InnerClassesTableEntry> classesList)

getClasses

public java.util.List<InnerClassesTableEntry> getClasses()
Description copied from interface: InnerClassesAttribute
Every CONSTANT_Class_info entry in the constant_pool table which represents a class or interface C that is not a package member must have exactly one corresponding entry in the classes array. If a class has members that are classes or interfaces, its constant_pool table (and hence its InnerClasses attribute) must refer to each such member, even if that member is not otherwise mentioned by the class. These rules imply that a nested class or interface member will have InnerClasses information for each enclosing class and for each immediate member.

Specified by:
getClasses in interface InnerClassesAttribute
Returns:
List This List will contain instances of the InnerClassesTableEntry class

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
