Class CRTable

java.lang.Object

com.sun.tools.javac.jvm.CRTable

All Implemented Interfaces:

CRTFlags

public class CRTable
extends Object
implements CRTFlags

This class contains the CharacterRangeTable for some method and the hashtable for mapping trees or lists of trees to their ending positions.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.

                int flags,
                int startPc,
                int endPc)

Create a new CRTEntry and add it to the entries.

Parameters:

tree - The tree or the list of trees for which we are storing the code pointers.

flags - The set of flags designating type of the entry.

startPc - The starting code position.

endPc - The ending code position.

public int writeCRT(ByteBuffer databuf,
                    Position.LineMap lineMap,
                    Log log)

Compute source positions and write CRT to the databuf.

Parameters:

databuf - The buffer to write bytecodes to.

length

public int length()

Return the number of the entries.
