Method Detail

setCustomResourceLoaders

public static void setCustomResourceLoaders(ResourceLoader... loaders)

Sets the custom resource loaders.

Parameters:

loaders - custom resource loaders

isResource

                                 ResourceLoader... loaders)

Returns whether the supplied path is supported by a ResourceLoader.

Parameters:

path - to inspect

loaders - to invoke ResourceLoader.supports(String) on

Returns:

whether the supplied string represents a resource

isResource

public static boolean isResource(String path)

Invokes isResource(String, ResourceLoader...) with DEFAULT_RESOURCE_LOADERS.

Parameters:

path - to inspect

Returns:

whether the supplied string represents a resource

getResource

public static InputStream getResource(String path,
                                      ResourceLoader... loaders)
                               throws IOException

Attempts to find a ResourceLoader that supports the supplied path. If found, that resource loader is used to load the input stream.

Parameters:

path - that designates a resource

loaders - to invoke ResourceLoader.load(String) on

Returns:

input stream to read the resource

Throws:

IOException - if the resource cannot be read

Reads the data from the supplied resource path using the supplied loaders. See getResource(String, ResourceLoader...) and LdapUtils.readInputStream(InputStream).

Parameters:

path - that designates a resource

loaders - to invoke getResource(String, ResourceLoader...) with

Returns:

bytes read from the resource

Throws:
