Method Detail

assembleRangeCheck

protected org.objectweb.asm.Label assembleRangeCheck(org.objectweb.asm.MethodVisitor mv)

Assemble the bytecode instructions to perform a range check on a primitive integer value in local variable 1 (the subscript parameter of an indexed getter/setter method), and to jump to the instruction represented by the returned label if the check passes. If the check fails, the instruction next visited by the caller is executed. It is up to the caller to assign the label to a jump destination.

The assembled method will delegate to the parent class' range check method for the range check itself.

Parameters:

mv - Method visitor

Returns:

Jump label, to allow the caller to determine the jump destination, in the event of a failed check (i.e., subscript is out of range).
