Examples of org.mozilla.javascript.Context.evaluateReader()

org.mozilla.javascript.Context.evaluateReader()
Evaluate a reader as JavaScript source. All characters of the reader are consumed. @param scope the scope to execute in @param in the Reader to get JavaScript source from @param sourceName a string describing the source, such as a filename @param lineno the starting line number @param securityDomain an arbitrary object that specifies securityinformation about the origin or owner of the script. For implementations that don't care about security, this value may be null. @return the result of evaluating the source @exception IOException if an IOException was generated by the Reader
