Constructor Detail

ForClassLoader

protected ForClassLoader(ClassLoader classLoader)

Creates a new class file locator for the given class loader.

Parameters:

classLoader - The class loader to query which must not be the bootstrap class loader, i.e. null.

Method Detail

ofClassPath

public static ClassFileLocator ofClassPath()

Creates a class file locator that queries the system class loader.

Returns:

A class file locator that queries the system class loader.

of

public static ClassFileLocator of(ClassLoader classLoader)

Creates a class file locator for a given class loader.

Parameters:

classLoader - The class loader to be used. If this class loader represents the bootstrap class loader which is represented by the null value, this system class loader is used instead.

Returns:

A corresponding source locator.

read

public static ClassFileLocator.Resolution read(Class<?> type)

Attempts to create a binary representation of a loaded type by requesting data from its ClassLoader.

Parameters:

type - The type of interest.

Returns:

The binary data to this type which might be illegal.

locate

public ClassFileLocator.Resolution locate(String typeName)
                                   throws IOException

Description copied from interface: ClassFileLocator

Locates the class file for a given type and returns the binary data of the class file.

Specified by:

locate in interface ClassFileLocator

Parameters:

typeName - The name of the type to locate a class file representation for.

Returns:

Any binary representation of the type which might be illegal.

Throws:

IOException - If reading a class file causes an error.

locate

protected static ClassFileLocator.Resolution locate(ClassLoader classLoader,
                                                    String typeName)
                                             throws IOException

Locates the class file for the supplied type by requesting a resource from the class loader.

Parameters:

classLoader - The class loader to query for the resource.

typeName - The name of the type for which to locate a class file.

Returns:

A resolution for the class file.

Throws:

IOException - If reading the class file causes an exception.
