nl_tokens: The mappingThisOnly flag indicates that the only type parameter being mapped is this . When the flag is true we check symbols to see if we can quickly conclude they are free of this references thus needing no instantiation .
pl_tokens: function createInstantiatedSymbolTable ( symbols , mapper , mappingThisOnly ) { var <mask> = { } ; for ( var _i = 0 ; _i < symbols . length ; _i ++ ) { var symbol = symbols [ _i ] ; result [ symbol . name ] = mappingThisOnly && isIndependentMember ( symbol ) ? symbol : instantiateSymbol ( symbol , mapper ) ; } return result ; }
