nl_tokens: Produces a new SourceFile for the newText provided . The textChangeRange parameter indicates what changed between the text that this SourceFile has and the newText . The SourceFile will be created with the compiler attempting to reuse as many nodes from this file as possible . Note : this function mutates nodes from this SourceFile . That means any existing nodes from this SourceFile that are being held onto may change as a result ( including becoming detached from any SourceFile ) . It is recommended that this SourceFile not be used once update is called on it .
pl_tokens: function updateSourceFile ( sourceFile , newText , textChangeRange , aggressiveChecks ) { <mask> IncrementalParser . updateSourceFile ( sourceFile , newText , textChangeRange , aggressiveChecks ) ; }
