FileImageOutputStream
public FileImageOutputStream(File f)
throws FileNotFoundException,
IOException Constructs a FileImageOutputStream that will write to a given File.
- Parameters:
-
f- aFileto write to. - Throws:
-
IllegalArgumentException- iffisnull. -
SecurityException- if a security manager exists and does not allow write access to the file. -
FileNotFoundException- iffdoes 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- aRandomAccessFileto write to. - Throws:
-
IllegalArgumentException- ifrafisnull.
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- alongcontaining the desired file pointer position. - Throws:
-
IndexOutOfBoundsException- ifposis 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:
-
finalizein classImageInputStreamImpl - Throws:
-
Throwable- if an error occurs during superclass finalization. - See Also:
