Inherited methods

From class


        
          dalvik.system.BaseDexClassLoader

`Class<?>`	`findClass(String name)` Finds the class with the specified binary name.
`String`	`findLibrary(String name)` Returns the absolute path name of a native library.
`URL`	`findResource(String name)` Finds the resource with the given name.
`Enumeration<URL>`	`findResources(String name)` Returns an enumeration of `URL` objects representing all the resources with the given name.
`Package`	`getPackage(String name)` This method is deprecated. See `ClassLoader#getPackage(String)`
`String`	`toString()` Returns a string representation of the object.

From class


        
          java.lang.ClassLoader

`void`	`clearAssertionStatus()` Sets the default assertion status for this class loader to `false` and discards any package defaults or class assertion status settings associated with the class loader.
`final Class<?>`	`defineClass(String name, byte[] b, int off, int len, ProtectionDomain protectionDomain)` Converts an array of bytes into an instance of class `Class`, with a given `ProtectionDomain`.
`final Class<?>`	`defineClass(String name, ByteBuffer b, ProtectionDomain protectionDomain)` Converts a `ByteBuffer` into an instance of class `Class`, with the given `ProtectionDomain`.
`final Class<?>`	`defineClass(byte[] b, int off, int len)` This method was deprecated in API level 15. Replaced by `defineClass(String, byte[], int, int)`
`final Class<?>`	`defineClass(String name, byte[] b, int off, int len)` Converts an array of bytes into an instance of class `Class`.
`Package`	`definePackage(String name, String specTitle, String specVersion, String specVendor, String implTitle, String implVersion, String implVendor, URL sealBase)` Defines a package by name in this `ClassLoader`.
`Class<?>`	`findClass(String name)` Finds the class with the specified binary name.
`String`	`findLibrary(String libname)` Returns the absolute path name of a native library.
`final Class<?>`	`findLoadedClass(String name)` Returns the class with the given binary name if this loader has been recorded by the Java virtual machine as an initiating loader of a class with that binary name.
`URL`	`findResource(String name)` Finds the resource with the given name.
`Enumeration<URL>`	`findResources(String name)` Returns an enumeration of `URL` objects representing all the resources with the given name.
`final Class<?>`	`findSystemClass(String name)` Finds a class with the specified binary name, loading it if necessary.
`Package`	`getPackage(String name)` This method was deprecated in API level 35. If multiple class loaders delegate to each other and define classes with the same package name, and one such loader relies on the lookup behavior of `getPackage` to return a `Package` from a parent loader, then the properties exposed by the `Package` may not be as expected in the rest of the program. For example, the `Package` will only expose annotations from the `package-info.class` file defined by the parent loader, even if annotations exist in a `package-info.class` file defined by a child loader.
`Package[]`	`getPackages()` Returns all of the `Package`s that have been defined by this class loader and its ancestors.
`final ClassLoader`	`getParent()` Returns the parent class loader for delegation.
`URL`	`getResource(String name)` Finds the resource with the given name.
`InputStream`	`getResourceAsStream(String name)` Returns an input stream for reading the specified resource.
`Enumeration<URL>`	`getResources(String name)` Finds all the resources with the given name.
`static ClassLoader`	`getSystemClassLoader()` Returns the system class loader.
`static URL`	`getSystemResource(String name)` Find a resource of the specified name from the search path used to load classes.
`static InputStream`	`getSystemResourceAsStream(String name)` Open for reading, a resource of the specified name from the search path used to load classes.
`static Enumeration<URL>`	`getSystemResources(String name)` Finds all resources of the specified name from the search path used to load classes.
`Class<?>`	`loadClass(String name, boolean resolve)` Loads the class with the specified binary name.
`Class<?>`	`loadClass(String name)` Loads the class with the specified binary name.
`static boolean`	`registerAsParallelCapable()` Registers the caller as `#isRegisteredAsParallelCapable() parallel capable`.
`final void`	`resolveClass(Class<?> c)` Links the specified class.
`void`	`setClassAssertionStatus(String className, boolean enabled)` Sets the desired assertion status for the named top-level class in this class loader and any nested classes contained therein.
`void`	`setDefaultAssertionStatus(boolean enabled)` Sets the default assertion status for this class loader.
`void`	`setPackageAssertionStatus(String packageName, boolean enabled)` Sets the package default assertion status for the named package.
`final void`	`setSigners(Class<?> c, Object[] signers)` Sets the signers of a class.

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
