FindToken(Int32, Boolean)

Finds a token according to the following rules:

  1. If position matches the End of the node/s FullSpan and the node is CompilationUnit, then EoF is returned.

  2. If node.FullSpan.Contains(position) then the token that contains given position is returned.

  3. Otherwise an ArgumentOutOfRangeException is thrown

Declaration
public SyntaxToken FindToken(int position, bool findInsideTrivia = false)
Parameters
Type Name Description
System.Int32 position
System.Boolean findInsideTrivia
Returns
Type Description
