Public Methods
public boolean canRead ()
Determine whether this input is readable.
public void close ()
Close that input and free all resources used by this object.
public SeekableByteChannel getChannel ()
Get a seekable read-only channel representing the input. Each call returns a unique channel. Clients should use this method to efficiently read at various locations within the given input.
Returns
- a unique seekable channel
Throws
| IOException |
|---|
public long getCurrentSize ()
Provide the current input size of the input data.
Returns
- the size, -1 if the size cannot be calculated or if an error occurred
public ByteBuffer getHeader ()
Get a read-only, big-endian buffer of the first input bytes. Clients should not attempt to
modify or directly access that buffer. The initial position is set to 0. It is recommended
that implementations provide at least IDEAL_HEADER_SIZE bytes.
Returns
- a unique buffer; on error, the returned buffer is null (unlike other methods declared in this interface, this method does not throw IOException)
public String getName ()
Retrieve the optional input name.
public InputStream getStream ()
Get the input stream. Each call returns a unique stream. Implementors should offer this
method for convenience. The implementor is responsible for closing non-closed streams when
close() is called.
Returns
- a unique input stream
Throws
| IOException |
|---|
