Method Detail
-
sessionStarted
void sessionStarted()
Informs the computer that a content assist session has started. This call will always be followed by asessionEnded()
call, but not necessarily by calls to computeCompletionProposals or computeContextInformation.
-
computeCompletionProposals
List<ICompletionProposal> computeCompletionProposals(ContentAssistInvocationContext context, IProgressMonitor monitor)
Returns a list of completion proposals valid at the given invocation context.- Parameters:
context
- the context of the content assist invocationmonitor
- a progress monitor to report progress. The monitor is private to this invocation, i.e. there is no need for the receiver to spawn a sub monitor.- Returns:
- a list of completion proposals (element type:
ICompletionProposal
)
-
computeContextInformation
List<IContextInformation> computeContextInformation(ContentAssistInvocationContext context, IProgressMonitor monitor)
Returns context information objects valid at the given invocation context.- Parameters:
context
- the context of the content assist invocationmonitor
- a progress monitor to report progress. The monitor is private to this invocation, i.e. there is no need for the receiver to spawn a sub monitor.- Returns:
- a list of context information objects (element type:
IContextInformation
)
-
getErrorMessage
String getErrorMessage()
Returns the reason why this computer was unable to produce any completion proposals or context information.- Returns:
- an error message or
null
if no error occurred
-
sessionEnded
void sessionEnded()
Informs the computer that a content assist session has ended. This call will always be after any calls to computeCompletionProposals and computeContextInformation.
