Method Detail

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

fromStream

public void fromStream(java.io.DataInputStream dis,
                       Dna dna,
                       int nameIndex,
                       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

nameIndex - 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

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

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

innerValidations

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

Overrides:

innerValidations in class GenericAttribute

Throws:

AttributeValidationException

AttributeOutOfRangeException

MissingDnaContainerException

MissingCPTableException

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

setClassIndex

public void setClassIndex(int cIndx)

Description copied from interface: EnclosingMethodAttribute

Thevalue of theclass_index item must be a valid index into the constant_pool table. Theconstant_pool entry at that index mustbea CONSTANT_Class_info (�4.5.1) structure representing the innermost class that encloses the declaration of the current class.

Specified by:

setClassIndex in interface EnclosingMethodAttribute

getClassIndex

public int getClassIndex()

Description copied from interface: EnclosingMethodAttribute

Thevalue of theclass_index item must be a valid index into the constant_pool table. Theconstant_pool entry at that index mustbea CONSTANT_Class_info (�4.5.1) structure representing the innermost class that encloses the declaration of the current class.

Specified by:

getClassIndex in interface EnclosingMethodAttribute

setMethodIndex

public void setMethodIndex(int mIndx)

Description copied from interface: EnclosingMethodAttribute

If the current class is not immediately enclosed by a method or constructor, then the value of themethod_index item must be zero. Otherwise, the value of themethod_index item must be a valid index into theconstant_pool table. Theconstant_pool entry at that index must be a CONSTANT_NameAndType_info (�4.5.6) structure representing the name and type of a method in the class referenced by the class_index attribute above. It is the responsibility of the Java compiler to ensure that the method identified via themethod_index is indeed the closest lexically enclosing method of the class that contains this EnclosingMethod attribute.

Specified by:

setMethodIndex in interface EnclosingMethodAttribute

getMethodIndex

public int getMethodIndex()

Description copied from interface: EnclosingMethodAttribute

If the current class is not immediately enclosed by a method or constructor, then the value of themethod_index item must be zero. Otherwise, the value of themethod_index item must be a valid index into theconstant_pool table. Theconstant_pool entry at that index must be a CONSTANT_NameAndType_info (�4.5.6) structure representing the name and type of a method in the class referenced by the class_index attribute above. It is the responsibility of the Java compiler to ensure that the method identified via themethod_index is indeed the closest lexically enclosing method of the class that contains this EnclosingMethod attribute.
