SnapshotInputStreamSource (InputStream stream)

Constructor for a file-backed InputStreamSource

Parameters
stream InputStream

Public methods

cancel

void cancel ()

Do any required cleanup on the source of the InputStream. Calling this method essentially invalidates this InputStreamSource.

createInputStream

InputStream createInputStream ()

Return a new clone of the InputStream, so that the caller can read the stream from the beginning. Each invocation of this method (until cancel() is called) will return an identically-behaving InputStream -- the same contents will be returned.

Returns
InputStream An InputStream that the caller can use to read the data source from the beginning. May return null if this InputStreamSource has been invalidated by a prior call to cancel(), or if a new InputStream cannot be created for some other reason.

size

long size ()

Return the size in bytes of the source data.

Returns
long
