java.lang.Objectuk.ac.starlink.table.storage.FileByteStore
ByteStore implementation which uses a temporary file.
Constructor Summary | |
FileByteStore()
Constructs a new FileByteStore which uses a temporary file as backing store. |
|
FileByteStore(File file)
Constructs a new FileByteStore which uses the given file as a backing store. |
Method Summary | |
void |
close()
Tidies up. |
void |
copy(OutputStream out)
Takes all the data written so far into this store's sink stream and copies it to a destination stream. |
File |
getFile()
Returns the file used by this store. |
OutputStream |
getOutputStream()
Returns an output stream which can be used to write to the store. |
ByteBuffer |
toByteBuffer()
Returns a byte buffer containing the bytes written to this store. |

- if there is some I/O-related problem with
opening the file
