Class 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).

        Constructs a new TryCatchBlockSorter.
        Parameters:
        methodVisitor - the method visitor to which this visitor must delegate method calls. May be null.
        access - the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.
        name - the method's name.
        descriptor - the method's descriptor (see Type).
        signature - the method's signature. May be null if the method parameters, return type and exceptions do not use generic types.
        exceptions - the internal names of the method's exception classes (see Type.getInternalName()). May be null.
