getLocalTarget

public Entry getLocalTarget()
                     throws IOException

Description copied from class: IOSocket

Returns the local target for I/O operations.

Note that this interface contract does not state any other terms or conditions for the returned object. In particular, clients need to consider that multiple invocations of this method could return different objects (e.g. defensive copies) which may even fail the Object.equals(java.lang.Object) test. On the other hand, implementations need to consider that clients could attempt to change the state of the returned object in arbitrary manner. Consequently, the result of doing so is undefined, too. In particular, a subsequent I/O operation may not reflect the change or may even fail. Sub-interfaces or implementations may add additional terms and conditions in order to resolve these potential issues.

Specified by:

getLocalTarget in class IOSocket<Entry,Entry>

Returns:

The local target for I/O operations.

Throws:

IOException

newReadOnlyFile

public ReadOnlyFile newReadOnlyFile()
                             throws IOException

Description copied from class: InputSocket

Optional: Returns a new read only file for reading bytes from the local target in arbitrary order.

If this method is supported, implementations must enable calling it any number of times. Furthermore, the returned read only file should not be buffered. Buffering should be addressed by client applications instead.

Specified by:

newReadOnlyFile in class InputSocket<Entry>

Returns:

A new read only file.

Throws:

FileNotFoundException - if the local target does not exist or is not accessible for some reason.

IOException - on any other exceptional condition.

newInputStream

public InputStream newInputStream()
                           throws IOException

Description copied from class: InputSocket

Returns a new input stream for reading bytes from the local target.

Implementations must enable calling this method any number of times. Furthermore, the returned input stream should not be buffered. Buffering should be addressed by the caller instead - see IOSocket.copy(de.schlichtherle.truezip.socket.InputSocket, de.schlichtherle.truezip.socket.OutputSocket).

The implementation in the class InputSocket calls InputSocket.newReadOnlyFile() and wraps the resulting object in a new ReadOnlyFileInputStream as an adapter.

Overrides:

newInputStream in class InputSocket<Entry>

Returns:

A new input stream.

Throws:

FileNotFoundException - if the local target does not exist or is not accessible for some reason.

IOException - on any other exceptional condition.

getBuffer
