Class RewriteCallerCodeLocation

java.lang.Object
com.google.javascript.jscomp.RewriteCallerCodeLocation
All Implemented Interfaces:
CompilerPass
public final class RewriteCallerCodeLocation extends Object implements CompilerPass
Rewrites call-sites of functions that have goog.callerLocation as a default parameter.

E.g: function signal(val, here: goog.CodeLocation = goog.callerLocation()) {}

When a function is called without providing the optional `here` argument, we will rewrite the function call to include the code location.

i.e. `signal(0, goog.callerLocationIdInternalDoNotCallOrElse(path/to/file.ts:lineno:charno))`
