Class GridServiceDelegate

Direct Known Subclasses:

GdsDelegate

public class GridServiceDelegate

public void clearErrors()

Clears previously-caught exceptions, causing the object to behave as
if it has not yet caught an exception.

public String getErrorMessage()

Returns the error message from the last exception to be caught,
or "OK" if no exception has yet been caught.

public String getFactoryHandle()

Returns the Grid Service Handle for the factory that will make
the service instance managed by this delegate.

public String getInstanceHandle()
                          throws java.lang.Exception

Return the Grid Service Handle for the service instance.

public boolean getThrowsExceptions()

Determines whether this delegate throws exceptions
(the alternative is to catch the exceptions and to present
their messages through the bean properties).

public boolean isConnected()

Talks to the service and checks whether an instance is
connected to the delegate.

Returns: true if there is an instance connected; false otherwise.

public boolean isFailed()

Indicates whether this delegate has caught an exception
since construction or since the last call to clearErrors.

public boolean isSimulating()

Reports whether the delegate is simulating the
link with its service. The meaning of simulation
depends on the sub-classes of this class.

public void reportError(Exception e)
                  throws java.lang.Exception

Reports a given exception, either by throwing it or storing
it in the error property, according to the state of the
throwsException property.

public void setFactoryHandle(String factoryHandle)

Sets the Grid Service Handle for the factory that will make the
service instance managed by this delegate.

public void setSimulating(boolean simulating)

Sets the flag for simulation of the link with the
delegate's service. The interpretation of this flag
is determined by the subclasses of this class.

public void setThrowsExceptions(boolean throwsExceptions)

Specifies whether this delegate throws exceptions (the alternative is to catch the exceptions and to present
their messages through the bean properties).
