The obfuscateExceptionsUnexclude Statement
The ZKM Script obfuscateExceptionsUnexclude statement acts only on the set of excluded methods and classes created by an obfuscateExceptionsExclude statement.
The statement removes specified methods and classes from the set of excluded methods and classes so that they become available once more for exception obfuscation by the
ZKM Script obfuscate statement.
The obfuscateExceptionsUnexclude statement is intended to be used in conjunction with a obfuscateExceptionsExclude statement to specify
a final set of excluded methods and classes that would have been difficult to achieve using a obfuscateExceptionsExclude statement alone.
Typically, in such cases, an initial obfuscateExceptionsExclude statement would set the broad exclusions and then the obfuscateExceptionsUnexclude
statement would specify the exceptions to those broad exclusions.
Successive obfuscateExceptionsUnexclude statements have a cumulative effect. The effect of all exclusions and unexclusions that have been set is removed
by a resetObfuscateExceptionsExclusions statement.
The remainder of this page is organized into the following sections.
The syntax of the obfuscateExceptionsUnexclude statement is the same as that of the obfuscateExceptionsExclude statement.
obfuscateExceptionsUnexclude statement parameters may be loosely categorized into the following groups
Put informally (with mandatory components in bold), the syntax of a obfuscateExceptionsUnexclude class unexclude parameter is:
<classAnnotations> <classModifiers> "<archiveQualifier>"!<packageQualifiers>.<className> <containingClause> <extendsClause> <implementsClause>;
For a class and all of its methods to be unexcluded from exception obfuscation, all of the following must be true:
- Its annotations must match any specified annotations.
- Its modifiers (e.g.
public final) must match all parameter modifiers.
So if the parameters are public abstract !interface then the class must be
public, abstract and NOT an interface to be excluded.
- If the parameter has an archive qualifier then the class must be contained in an archive which matches that archive qualifier.
- Its package qualifiers must match any specified package exclude parameter component. If there is no
package exclude parameter component then the class must be in the default package.
- Its unqualified name must match the specified class name specification.
- If the parameter has a containing clause then the class must contain members which match the specified class
- If the parameter has an extends clause then the class must be a subclass of the specified class
- If the parameter has an implements clause then the class must directly or indirectly implement all of the specified interfaces

*.Class1 and //unexclude all methods in all classes with the unqualified class name "Class1"
//unexclude all methods in all classes that start with "Class" except for "Class0" and "Class1"

Put informally (with mandatory components in bold), the syntax of a obfuscateExceptionsUnexclude method unexclude parameter is:
<classAnnotations> <classModifiers> "<archiveQualifier>"!<packageQualifiers>.<className> <extendsClause> <implementsClause>
<methodAnnotations> <methodModifiers> <methodName>(<argumentTypes>) <throwsClause> +signatureClasses;
For a method to be unexcluded from exception obfuscation, all of the following must be true:
- Its containing class must match any class unexclude 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 excluded from obfuscation.
- Its name must match the parameter method name specification.
The special name
<init> matches all constructors and the special name <clinit>
matches all static initializers.
- 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 obfuscateExceptionsExclude parameter's throw clause.
So, if the obfuscateExceptionsExclude parameter's throws clause is
throws java.io.IOException then the method
must throw java.io.IOException or one of its subclasses to be excluded.
