Class SortedBlocks
java.lang.Objectorg.jxcl.cl.SortedBlocks
- public class SortedBlocks
- extends java.lang.Object
Manages an index into the bytecode vertices in a method's control flow graph. The vertices (blocks) are indexed by their position in the original code. The blocks may be from different graphs in a set of nested graphs.

| Method Detail |
add
public boolean add(CodeVertex v)
- Add a vertex at its bytecode position. * It is an
error if there is already a vertex at this position.
XXX SHOULD THROW EXCEPTION IN SUCH A CASE.
find
public CodeVertex find(int pos, ControlFlowGraph currGraph, org.jxcl.graph.Edge e)
- Find or create a code vertex starting at a given position.
add
public CodeVertex add(int pos, org.jxcl.graph.Edge e)
- Add a vertex at bytecode offset pos along edge e. No other
vertex with that bytecode offset may exist.
exists
public boolean exists(int pos)
- Does a vertex exist with this bytecode offset?
get
public CodeVertex get(int pos)
- Find the code vertex starting at a given bytecode offset.
The vertex must exist. XXX Should throw an exception if
it doesn't.
size
public int size()
- How many code vertices are currently in the index?
toString
public java.lang.String toString()
- Standard toString(), XXX needs some work.
