public class RereadableInputStream extends InputStream
Constructor and Description |
---|
RereadableInputStream(InputStream inputStream)
Creates a rereadable input stream with defaults of 512*1024*1024 bytes (500M) for
maxBytesInMemory and both readToEndOfStreamOnFirstRewind and closeOriginalStreamOnClose
set to true
|
RereadableInputStream(InputStream inputStream,
boolean closeOriginalStreamOnClose)
Creates a rereadable input stream defaulting to 512*1024*1024 bytes (500M) for
maxBytesInMemory
|
RereadableInputStream(InputStream inputStream,
int maxBytesInMemory)
Creates a rereadable input stream with closeOriginalStreamOnClose set to true
|
RereadableInputStream(InputStream inputStream,
int maxBytesInMemory,
boolean closeOriginalStreamOnClose)
Creates a rereadable input stream.

void |
close()
Closes the input stream and removes the temporary file if one was
created.
|
int |

read from the original stream.
|
void |
rewind()
"Rewinds" the stream to the beginning for rereading.
