        Utility method for IdentifierExpr and SelectExpr to apply the data binding contract to a given property of the referenced object. When referenceOnly = true, this is a getX reference only - not requiring that the referred property be made bindable. This method both ensures the property is registered with it's parent type and adds a reference to that type in ReverseDependencies - reflecting the dependency from the type which needs this property bindable. When checkAnnotations is true, referenceOnly starts out false but then turns to 'true' if this property is marked as @Bindable so that we inject it during the code-gen phase (i.e. not manual bindable).

        Description copied from class: JavaSemanticNode
        This works like suggestCompletions but designed to conform to the requirements of IntelliJ. We don't support the live programming use case in this version and have access (possibly) to the original model and original node which most closely approximates this node which is being parsed (so we can use more context to do a better job of matching because those values are all resolved).

        Description copied from class: JavaSemanticNode
        Used to create a list of suggestions to complete this node. Returns the character offset into the parse-tree (or command string if there's no parse tree) where the completion should start. Parameters: prefix is the starting sequence of chars in the identifier to complete. All candidates returned will start with the prefix if it's provided. currentType provides a context for the current type if the node is not embedded in a model - i.e. an identifier expression on its own but known to live in a specific type If ctx is not null, it's an execution context we can use to evaluate the "root value" - i.e. in a.b the value of the variable 'a' is evaluated and the returned instance can be used to suggest candidates. This is useful in live-programming situations. The command String parameter is used to determine the offset returned for where the completion starts for the case where the parseNode tree is not available.

      • applyPartialValue

        public boolean applyPartialValue​(java.lang.Object value)
        Description copied from class: JavaSemanticNode
        When Parser.enablePartialValues is set, and we do not complete parsing the input we'll have a set of errors which represent model fragments. In some cases, it would be nice to put the model together as well as possible for code hinting. This method can append fragments onto it... if so return true.

      • styleNode

        public void styleNode​(IStyleAdapter adapter)
        Styling for identifier expressions is complicated because the information we need to do the styling is at this level, but the elements we are styling are buried down in the parse-tree of this node. So far this is the only problematic case for Java so we are living with it but adding some features at the parselets level would help. One problem is that the parseNode for the IdentifierExpression may be expression, optExpression or exprStatement. We optionally need to 'drill down' to get the parse-node for the IdentifierExpression, then wrap the output with any parse nodes we skipped before or after. To handle this at the parselet level, we could skip those levels automatically. Another problem is that the path name is split into the first name, then "." followed by each subsequent name so there's an extra bump in the hierarchy to deal with the second and subsequent path-names. We could add a method called - childStyleHandler which is called for each child parse node that produces an array value (in this case, the identifiers array). It would return null for parse nodes which are ignored in styling or 'member' or 'staticMember' as necessary for each segment in the identifiers array. That method would be passed the current parent parse node, the child-index, and the current parse-node so it could go back into the identifier expression and find the right style for that segment of the path-name. It could probaby just unmap the value array and deal with the hierarchy skip so maybe we don't need that much context in that method.

        Description copied from interface: ISemanticNode
        Performs a deep copy of the semantic node tree. Subclasses should do their own copy implementation to decide what else to copy. Uses the copy options flags above. The default, with 0, just copies the semantic node information so you get a new tree like's it parsed but without parse node info. Use that mode only if you want to throw away the original source and regenerate it all from scratch. Otherwise, you can copy the parse tree as well. If you want to copy the semantic node's initial resolved state - including it's init/start, etc. and whatever the subclass adds to that copy, use CopyState or CopyNormal - for both parse nodes and state.

        Disables the optimization where 'object foo extends bar' omits class foo for simple configuration objects. Certain constructs like methods, fields, clearly disable this. Others like EnclosingType.this also will because we can only evaluate that expression in the context of a class (unless I suppose the object happens to be a child of the same outer type)
