Method Detail

canHandleOperation

public boolean canHandleOperation(DOOperationContext context)

Description copied from interface: DOOperation

Returns true iff this object can perform the given operation on behalf of the caller on the given object. The operation, object, caller, and request parameters are all provided by the given DOOperationContext object.

Specified by:

canHandleOperation in interface DOOperation

executeInContext

public void executeInContext()

Specified by:

executeInContext in class net.cnri.knowbots.lib.Knowbot

listOperations

public java.lang.String[] listOperations(DOOperationContext context)

Returns the list of operations that this knowbot can perform in the given context.

Specified by:

listOperations in interface DOOperation

DOOperation.listOperations(net.cnri.dobj.DOOperationContext)

performOperation

public void performOperation(DOOperationContext context,
                    java.io.InputStream in,
                    java.io.OutputStream out)

Description copied from interface: DOOperation

Performs the given operation (which this object has advertised that it can handle) which consists of reading input (if any is expected) from the given InputStream and writing the output of the operation (if any) to the OutputStream. This method should always close the input and output streams when finished with them. If there are any errors in the input, the error message must be communicated on the OutputStream since all errors must be at the application level. Any exceptions thrown by this method will *not* be communicated to the caller and are therefore not acceptable.
