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
