Method Details

filter

public void filter(org.objectweb.asm.tree.MethodNode methodNode,
 IFilterContext context,
 IFilterOutput output)

Description copied from interface: IFilter

This method is called for every method. The filter implementation is expected to inspect the provided method and report its result to the given IFilterOutput instance.

Specified by:

filter in interface IFilter

Parameters:

methodNode - method to inspect

context - context information for the method

output - callback to report filtering results to

filter

private void filter(org.objectweb.asm.tree.AbstractInsnNode start,
 IFilterOutput output)

javac generates two switches. First one by String.hashCode(). Number of handlers in the second switch is equal to number of handlers in source code, so it is enough to completely filter-out first switch. Handler for default case of the first switch - is the second switch.
