The methodParameterChangesInclude Statement
The ZKM Script methodParameterChangesInclude statement allows you to specify which methods should be considered as being available for parameter list changes.
Method parameters may be changed by a following obfuscate statement which has:
- Its
allowMethodParameterChanges parameter set to true and
- Its
encryptStringLiterals parameter set to enhanced and/or
- Its
obfuscateReferences parameter set to normal.
Successive methodParameterChangesInclude statements have a cumulative effect. Once a specification has been set its effect can be
If there is a methodParameterChangesInclude statement without a methodParameterChangesExclude statement
then only the methods specified by the methodParameterChangesInclude statement will be considered as candidates for parameter changes.
If there is a methodParameterChangesInclude statement and a methodParameterChangesExclude statement then the
methodParameterChangesInclude statement will be applied first against the set of all methods and then
the methodParameterChangesExclude statement will be applied against the set of methods specified by the
methodParameterChangesInclude statement.
Note that if there is neither a methodParameterChangesInclude statement or a methodParameterChangesExclude statement
active then the obfuscate statement will default to treating all methods as candidates.
The remainder of this page is organized into the following sections.
methodParameterChangesInclude statement parameters must specify methods.
Put informally (with mandatory components in bold), the syntax is:
<classAnnotations> <classModifiers> <packageQualifiers>.<className> <extendsClause> <implementsClause>
<methodAnnotations> <methodModifiers> <methodName>(<argumentTypes>) <throwsClause> +signatureClasses;
For a method to be matched by the statement, all of the following must be true:
- Its containing class must match any class include parameter component.
- Its annotations must match any specified method or method parameter level annotations.
- Its modifiers (e.g.
public native) must match all parameter method modifiers.
So if the parameters are public static !synchronized then the method must be
public, static and NOT synchronized to be matched.
- Its name must match the parameter method name.
- Its argument types (e.g.
int[], java.lang.String) must match the parameter argument types if they exist.
(A single parameter argument type of "*" matches any method argument types including no arguments.)
If the parameter has no argument type then the method must take no arguments.
- Its throws clause must contain all the classes specified in the include parameter's throw clause.
So, if the include parameter's throws clause is
throws java.io.IOException then the method
must throw java.io.IOException or one of its subclasses to be matched.
