限定符和类型	方法和说明
boolean	isClassInSystemPackage(soot.SootClass clazz) Checks whether the given class belongs to a system package
boolean	isClassInSystemPackage(String className) Checks whether the given class name belongs to a system package
boolean	isClassInSystemPackage(soot.Type type) Checks whether the type belongs to a system package
boolean	isStubImplementation(soot.Body body) Checks whether the given method body is a stub implementation and can safely be overwritten
boolean	isTaintVisible(AccessPath taintedPath, soot.SootMethod method) If the base object is tainted and in a system class, but we reference some field in an application object derived from the system class, no tainting happens.
void	setExcludeSystemComponents(boolean excludeSystemComponents) Sets whether components in system or framework-related packages shall be excluded from the analysis

SystemClassHandler

public SystemClassHandler()

方法详细资料

v

public static SystemClassHandler v()

Gets the global system class handler instance

返回:

The global system class handler instance

setInstance

public static void setInstance(SystemClassHandler instance)

Overwrites the global system class handler instance

参数:

instance - The new the global system class handler instance

isClassInSystemPackage

public boolean isClassInSystemPackage(soot.SootClass clazz)

Checks whether the given class belongs to a system package

参数:

clazz - The class to check

返回:

True if the given class belongs to a system package, otherwise false

isClassInSystemPackage

public boolean isClassInSystemPackage(String className)

Checks whether the given class name belongs to a system package

参数:

className - The class name to check

返回:

True if the given class name belongs to a system package, otherwise false

isClassInSystemPackage

public boolean isClassInSystemPackage(soot.Type type)

Checks whether the type belongs to a system package

参数:

type - The type to check

返回:

True if the given type belongs to a system package, otherwise false

isTaintVisible

public boolean isTaintVisible(AccessPath taintedPath,
                              soot.SootMethod method)

If the base object is tainted and in a system class, but we reference some field in an application object derived from the system class, no tainting happens. The system class cannot access or know about user-code fields. This leaves reflection aside, but we don't support reflection anyway.

参数:

taintedPath - The access path of the incoming taint

method - The method that gets called

返回:

True if the given taint is visible to the callee, otherwise false

setExcludeSystemComponents

public void setExcludeSystemComponents(boolean excludeSystemComponents)

Sets whether components in system or framework-related packages shall be excluded from the analysis

参数:

excludeSystemComponents - True to exclude components in system packages from the analysis, false otherwise

isStubImplementation

public boolean isStubImplementation(soot.Body body)

Checks whether the given method body is a stub implementation and can safely be overwritten

参数:

body - The body to check

返回:

True if the given method body is a stub implementation, otherwise false
