public class MultipleEquationParser extends Object
A parser which can be used to parse multiple expressions in sequence. Separate instances can be used in multiple threads to allow parallel parsing of multiple sets of expressions.

The class is initialized by the constructor MultipleEquationParser(ConfigurableParser, Reader) constructor with a Reader containing the input stream. The continueParsing() method to return the result of parsing the next expression in the stream.

      public MultipleEquationParser(ConfigurableParser threadSafeConfigurbleParser, Reader input)
      Creates a new parser for the given stream.
      Parameters:
