Class TryCatchBlockSorter

java.lang.Object

bboss.org.objectweb.asm.MethodVisitor

bboss.org.objectweb.asm.tree.MethodNode

bboss.org.objectweb.asm.commons.TryCatchBlockSorter

public class TryCatchBlockSorter
extends MethodNode

A MethodVisitor adapter to sort the exception handlers. The handlers are sorted in a method innermost-to-outermost. This allows the programmer to add handlers without worrying about ordering them correctly with respect to existing, in-code handlers. Behavior is only defined for properly-nested handlers. If any "try" blocks overlap (something that isn't possible in Java code) then this may not do what you want. In fact, this adapter just sorts by the length of the "try" block, taking advantage of the fact that a given try block must be larger than any block it contains).
