      • getInputToParse

        public java.lang.String getInputToParse​(java.lang.String completeInput,
                                        int offset,
                                        int completionOffset)
        Standard languages only need to parse the text up to the last hidden token sequence in the document. Thus the string from start to the normalized offset is sufficient.

      • getLastCompleteNodeByOffset

        public org.eclipse.xtext.nodemodel.INode getLastCompleteNodeByOffset​(org.eclipse.xtext.nodemodel.INode node,
                                                                     int offsetPosition,
                                                                     int completionOffset)
        Returns the last node that appears to be part of the prefix. This will be used to determine the current model object that'll be the most special context instance in the proposal provider.
