Public Methods

Method	Description
GetDataTipExpression ( IAstNode ast, ITextRange range ) : IAstNode	Given an R AST, and a range in that AST, determines the DataTip expression for that range. DataTip expression is defined as the outermost expression enclosing the range, such that the sequence of operators from that outermost expression to the innermost node still enclosing the range only consists of operators: `$ @ :: ::: [ [[`. Furthermore, in case of `[ [[`, only their left operands are considered.

Private Methods

Method	Description
IsValidInitialNode ( IAstNode node ) : bool	Determines whether hovering over the AST node provided should trigger the DataTip.

Given an R AST, and a range in that AST, determines the DataTip expression for that range.

DataTip expression is defined as the outermost expression enclosing the range, such that the sequence of operators from that outermost expression to the innermost node still enclosing the range only consists of operators: $ @ :: ::: [ [[. Furthermore, in case of [ [[, only their left operands are considered.
