unwrap in interface FileResource

Type Parameters:

T -

Parameters:

type -

Returns:

backend if supported

Throws:

UnsupportedOperationException

openInputStream

public InputStream openInputStream()
                            throws IOException

Description copied from interface: FileResource

Opens a new input stream to read the contents of a resource and returns it. Note that implementations may be allocating native memory for the stream, so callers need to close this when they are done with it. users of this method should follow the pattern: close the stream where you open it.

Specified by:

openInputStream in interface FileResource

Returns:

InputStream

Throws:

IOException

Specified by:

openChannel in interface FileResource

Throws:

IOException

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:
