Method Details

setAttributeName

public static void setAttributeName(CPUTF8 cpUTF8Value)

getLength

protected int getLength()

Specified by:

getLength in class BCIRenumberedAttribute

getNestedClassFileEntries

protected ClassFileEntry[] getNestedClassFileEntries()

Overrides:

getNestedClassFileEntries in class Attribute

getStartPCs

protected int[] getStartPCs()

Specified by:

getStartPCs in class BCIRenumberedAttribute

renumber

public void renumber(List<Integer> byteCodeOffsets)
              throws Pack200Exception

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

Throws:

Pack200Exception - Thrown from a subclass.

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 - TODO

setCodeLength

public void setCodeLength(int length)

toString

public String toString()

Specified by:

toString in class BCIRenumberedAttribute

writeBody

protected void writeBody(DataOutputStream dos)
                  throws IOException

Specified by:

writeBody in class BCIRenumberedAttribute

Throws:

IOException
