public CompositeClassLoader(java.lang.ClassLoader loader1,
                            java.lang.ClassLoader loader2)

Create a CompositeClassLoader with two class loaders.

Parameters:

loader1 -

loader2 -

CompositeClassLoader

public CompositeClassLoader(java.util.List<java.lang.ClassLoader> loaders)

Create a CompositeClassLoader from a list of class loaders.

Parameters:

loaders -

Method Detail

public java.util.List<java.lang.ClassLoader> getClassLoaders()

Get the contained class loaders.

Returns:

the list of the contained class loaders

clearAssertionStatus

public void clearAssertionStatus()

Sets the default assertion status for this class loader to false and discards any package defaults or class assertion on all contained class loaders.

Overrides:

clearAssertionStatus in class java.lang.ClassLoader

getResource

public java.net.URL getResource(java.lang.String name)

Finds the resource with the given name. Contained class loaders are queried until one returns the requested resource or null if not found.

Overrides:

getResource in class java.lang.ClassLoader

See Also:

ClassLoader.getResource(String)

getResourceAsStream

public java.io.InputStream getResourceAsStream(java.lang.String name)

Returns an input stream for reading the specified resource. Contained class loaders are queried until one returns the requested resource stream or null if not found.

Overrides:

See Also:

ClassLoader.getResourceAsStream(String)

getResources

public java.util.Enumeration<java.net.URL> getResources(java.lang.String name)
                                                 throws java.io.IOException

Finds all the resources with the given name. Contained class loaders are queried and the results aggregated into a single Enumeration.

Overrides:

getResources in class java.lang.ClassLoader

Throws:

java.io.IOException - If I/O errors occur

See Also:
