Method Detail

generate

public java.lang.String generate(soot.SootClass source)

Generate code for a method that looks up interface method calls in a table and calls the correct function accordingly.

Parameters:

source - The class for which such a method needs to be generated.

Returns:

The code for the method.

getLookupMethods

public static java.util.HashMap getLookupMethods(soot.SootClass source)

Returns the list of all methods that may need to be looked up. Provides a mapping from the interface's method to the corresponding method in the class that implements it.

Parameters:

source - The class for which this set is to be generated.

Returns:

The set of all methods that may need to be looked up.

needsLookupFunction

public static boolean needsLookupFunction(soot.SootClass source)

Finds out whether a class needs a lookup function.

Parameters:

source - The class.

Returns:

True if the class has at least one required method (@see RequiredFileGenerator.isRequired) that is defined in an interface implemented by the class.
