Method Summary

Modifier and Type	Method and Description
static URL	getResource(String resource, boolean classesFirst, Class<?>... classes) If classesFirst is false, retrieves the resource via the context class loader of the current thread, and if not found, via the class loaders of the optionally specified classes in the order of their specification, and if not found, from the class loader of ClassLoaderHelper as the last resort.
static InputStream	getResourceAsStream(String resource, boolean classesFirst, Class<?>... classes) If classesFirst is false, retrieves the resource as an input stream via the context class loader of the current thread, and if not found, via the class loaders of the optionally specified classes in the order of their specification, and if not found, from the class loader of ClassLoaderHelper as the last resort.
static InputStream	getResourceAsStream(String resource, Class<?>... classes) Retrieves the resource as an input stream via the context class loader of the current thread, and if not found, via the class loaders of the optionally specified classes in the order of their specification, and if not found, from the class loader of ClassLoaderHelper as the last resort.
static ClassLoaderHelper	valueOf(String name) Returns the enum constant of this type with the specified name.
static ClassLoaderHelper[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

public static ClassLoaderHelper[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ClassLoaderHelper c : ClassLoaderHelper.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ClassLoaderHelper valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getResource

public static URL getResource(String resource,
                              boolean classesFirst,
                              Class<?>... classes)

If classesFirst is false, retrieves the resource via the context class loader of the current thread, and if not found, via the class loaders of the optionally specified classes in the order of their specification, and if not found, from the class loader of ClassLoaderHelper as the last resort.

If classesFirst is true, retrieves the resource via the optionally specified classes in the order of their specification, and if not found, via the context class loader of the current thread, and if not found, from the class loader of ClassLoaderHelper as the last resort.

Parameters:

resource - resource to be loaded

classesFirst - true if the class loaders of the optionally specified classes take precedence over the context class loader of the current thread; false if the opposite is true.

classes - class loader providers

Returns:

the resource loaded as an URL or null if not found.

getResourceAsStream

public static InputStream getResourceAsStream(String resource,
                                              Class<?>... classes)

Retrieves the resource as an input stream via the context class loader of the current thread, and if not found, via the class loaders of the optionally specified classes in the order of their specification, and if not found, from the class loader of ClassLoaderHelper as the last resort.

Parameters:

resource - resource to be loaded

classes - class loader providers

Returns:

the resource loaded as an input stream or null if not found.

getResourceAsStream

public static InputStream getResourceAsStream(String resource,
                                              boolean classesFirst,
                                              Class<?>... classes)

If classesFirst is false, retrieves the resource as an input stream via the context class loader of the current thread, and if not found, via the class loaders of the optionally specified classes in the order of their specification, and if not found, from the class loader of ClassLoaderHelper as the last resort.

If classesFirst is true, retrieves the resource as an input stream via the optionally specified classes in the order of their specification, and if not found, via the context class loader of the current thread, and if not found, from the class loader of ClassLoaderHelper as the last resort.

Parameters:

resource - resource to be loaded

classesFirst - true if the class loaders of the optionally specified classes take precedence over the context class loader of the current thread; false if the opposite is true.

classes - class loader providers

Returns:

the resource loaded as an input stream or null if not found.
