Constructor Detail
FileImageOutputStream
public FileImageOutputStream(File f) throws FileNotFoundException, IOException
Constructs a FileImageOutputStream
that will write to a given File
.
- Parameters:
-
f
- aFile
to write to. - Throws:
-
IllegalArgumentException
- iff
isnull
. -
SecurityException
- if a security manager exists and does not allow write access to the file. -
FileNotFoundException
- iff
does not denote a regular file or it cannot be opened for reading and writing for any other reason. -
IOException
- if an I/O error occurs.
FileImageOutputStream
public FileImageOutputStream(RandomAccessFile raf)
Constructs a FileImageOutputStream
that will write to a given RandomAccessFile
.
- Parameters:
-
raf
- aRandomAccessFile
to write to. - Throws:
-
IllegalArgumentException
- ifraf
isnull
.
Method Detail
seek
public void seek(long pos) throws IOException
Sets the current stream position and resets the bit offset to 0. It is legal to seeking past the end of the file; an EOFException
will be thrown only if a read is performed. The file length will not be increased until a write is performed.
- Parameters:
-
pos
- along
containing the desired file pointer position. - Throws:
-
IndexOutOfBoundsException
- ifpos
is smaller than the flushed position. -
IOException
- if any other I/O error occurs.
finalize
@Deprecated(since="9") protected void finalize() throws Throwable
finalize
method has been deprecated. Subclasses that override finalize
in order to perform cleanup should be modified to use alternative cleanup mechanisms and to remove the overriding finalize
method. When overriding the finalize
method, its implementation must explicitly ensure that super.finalize()
is invoked as described in Object.finalize()
. See the specification for Object.finalize()
for further information about migration options.Finalizes this object prior to garbage collection. The close
method is called to close any open input source. This method should not be called from application code.
- Overrides:
-
finalize
in classImageInputStreamImpl
- Throws:
-
Throwable
- if an error occurs during superclass finalization. - See Also:
