SecureClassLoader

Class Overview

SecureClassLoaders are used to dynamically load, link and install classes into a running image. Additionally, they (optionally) associate the classes they create with a code source and provide mechanisms to allow the relevant permissions to be retrieved.

Summary

[Expand] Inherited Methods
From class java.lang.ClassLoader void clearAssertionStatus() Clears the default, package and class assertion status of a classloader final Class<?> defineClass(byte[] classRep, int offset, int length) This method is deprecated. Use defineClass(String, byte[], int, int) final Class<?> defineClass(String name, ByteBuffer b, ProtectionDomain protectionDomain) Defines a new class for the name, bytecodes in the byte buffer and the protection domain. final Class<?> defineClass(String className, byte[] classRep, int offset, int length, ProtectionDomain protectionDomain) Constructs a new class from an array of bytes containing a class definition in class file format and assigns the new class to the specified protection domain. final Class<?> defineClass(String className, byte[] classRep, int offset, int length) Constructs a new class from an array of bytes containing a class definition in class file format. Package definePackage(String name, String specTitle, String specVersion, String specVendor, String implTitle, String implVersion, String implVendor, URL sealBase) Define a new Package using the specified information. Class<?> findClass(String className) Overridden by subclasses, by default throws ClassNotFoundException. String findLibrary(String libName) Returns the absolute path of the file containing the library associated with the given name, or null. final Class<?> findLoadedClass(String className) Attempts to find and return a class which has already been loaded by the virtual machine. URL findResource(String resName) Returns an URL which can be used to access the resource described by resName, using the class loader's resource lookup algorithm. Enumeration<URL> findResources(String resName) Returns an Enumeration of URL which can be used to access the resources described by resName, using the class loader's resource lookup algorithm. final Class<?> findSystemClass(String className) Attempts to load a class using the system class loader. Package getPackage(String name) Attempt to locate the requested package. Package[] getPackages() Return all the packages known to this class loader. final ClassLoader getParent() Returns the specified ClassLoader's parent. URL getResource(String resName) Returns an URL which can be used to access the resource described by resName, using the class loader's resource lookup algorithm. InputStream getResourceAsStream(String resName) Returns a stream on a resource found by looking up resName using the class loader's resource lookup algorithm. Enumeration<URL> getResources(String resName) Returns an Enumeration of URL which can be used to access the resources described by resName, using the class loader's resource lookup algorithm. static ClassLoader getSystemClassLoader() Returns the system class loader. static URL getSystemResource(String resName) Returns an URL specifying a resource which can be found by looking up resName using the system class loader's resource lookup algorithm. static InputStream getSystemResourceAsStream(String resName) Returns a stream on a resource found by looking up resName using the system class loader's resource lookup algorithm. static Enumeration<URL> getSystemResources(String resName) Returns an Enumeration of URLs containing all resources which can be found by looking up resName using the system class loader's resource lookup algorithm. Class<?> loadClass(String className) Invoked by the Virtual Machine when resolving class references. Class<?> loadClass(String className, boolean resolve) Loads the class with the specified name, optionally linking the class after load. final void resolveClass(Class<?> clazz) Forces a class to be linked (initialized). void setClassAssertionStatus(String cname, boolean enable) Sets the assertion status of a class. void setDefaultAssertionStatus(boolean enable) Sets the default assertion status of a classloader void setPackageAssertionStatus(String pname, boolean enable) Sets the assertion status of a package. final void setSigners(Class<?> c, Object[] signers) Sets the signers of a class.
From class java.lang.Object Object clone() Returns a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver. boolean equals(Object o) Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison. void finalize() Called by the virtual machine when there are no longer any (non-weak) references to the receiver. final Class<? extends Object> getClass() Returns the unique instance of java.lang.Class which represents the class of the receiver. int hashCode() Returns an integer hash code for the receiver. final void notify() Causes one thread which is wait ing on the receiver to be made ready to run. final void notifyAll() Causes all threads which are wait ing on the receiver to be made ready to run. String toString() Returns a string containing a concise, human-readable description of the receiver. final void wait(long time, int frac) Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout. final void wait(long time) Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout. final void wait() Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
