|

//
|
||||
// FastSourceLineResolver is a sibling class of BasicSourceLineResolver. The
|
||||
// difference is FastSourceLineResolver loads a serialized memory chunk of data
|
||||
// which can be used directly a Module without parsing or copying of underlying
|

// data. Therefore loading a symbol in FastSourceLineResolver is much faster
|
||||
// and more memory-efficient than BasicSourceLineResolver.
