NewAttribute

public NewAttribute(CPUTF8 attributeName,
 int layoutIndex)

Method Details

addBCIndex

public void addBCIndex(int length,
 int value)

addBCLength

public void addBCLength(int length,
 int value)

addBCOffset

public void addBCOffset(int length,
 int value)

addInteger

public void addInteger(int length,
 long value)

addToBody

public void addToBody(int length,
 Object value)

getLayoutIndex

public int getLayoutIndex()

getLength

protected int getLength()

Description copied from class: Attribute

Gets the length.

Specified by:

getLength in class BCIRenumberedAttribute

Returns:

the length.

getNestedClassFileEntries

protected ClassFileEntry[] getNestedClassFileEntries()

Description copied from class: ClassFileEntry

Returns an empty array.

Overrides:

getNestedClassFileEntries in class Attribute

Returns:

an empty array.

getStartPCs

protected int[] getStartPCs()

Description copied from class: BCIRenumberedAttribute

Gets the array of indices for the start of line numbers.

Specified by:

getStartPCs in class BCIRenumberedAttribute

Returns:

the array of indices for the start of line numbers.

renumber

public void renumber(List<Integer> byteCodeOffsets)

Description copied from class: BCIRenumberedAttribute

In Pack200, line number tables are BCI renumbered. This method takes the byteCodeOffsets (which is a List of Integers specifying the offset in the byte code array of each instruction) and updates the start_pcs so that it points to the instruction index itself, not the BCI renumbering of the instruction.

Overrides:

renumber in class BCIRenumberedAttribute

Parameters:

byteCodeOffsets - List of Integer offsets of the byte code array.

resolve

protected void resolve(ClassConstantPool pool)

Description copied from class: ClassFileEntry

Allows the constant pool entries to resolve their nested entries.

Overrides:

resolve in class Attribute

Parameters:

pool - The class constant pool.

toString

public String toString()

Specified by:

toString in class BCIRenumberedAttribute

writeBody

protected void writeBody(DataOutputStream dos)
                  throws IOException

Description copied from class: Attribute

Writes this body to the given output stream.

Specified by:

writeBody in class BCIRenumberedAttribute

Parameters:

dos - the output stream.

Throws:

IOException - if an I/O error occurs.
