Package com.singularsys.jep.misc.parallelparsing

Class MultipleEquationParsingJep

java.lang.Object

com.singularsys.jep.Jep

com.singularsys.jep.misc.parallelparsing.MultipleEquationParsingJep

All Implemented Interfaces:

Serializable

public class MultipleEquationParsingJep
extends Jep

A Jep which uses a ParallelConfigurableParser providing implementations of the Jep.initMultiParse(java.io.Reader) and continueParsing() methods. Note those methods are only intended to run in a single thread, and this class is only intended to provide compatibility.

To allow multiple threads to each parse sequences of expressions. The ParallelConfigurableParser.newMultipleEquationParser(java.io.Reader) method should be used to create a new MultipleEquationParser, once per thread. Its MultipleEquationParser.continueParsing() method can be called multiple times to parse the sequence of expressions specified in the Reader.

Constructor Details

MultipleEquationParsingJep

public MultipleEquationParsingJep(ParallelConfigurableParser tscp,
 JepComponent... components)

Creates a new MultipleEquationParsingJep using the given ParallelConfigurableParser and components.

Parameters:

tscp - the ParallelConfigurableParser

components - other components

Method Details

initMultiParse

public void initMultiParse(String str)

Creates a new MultipleEquationParser for the given string. Storing it in a field for later use by the continueParsing() method.

Overrides:

initMultiParse in class Jep

Parameters:

str - String containing a sequence of expressions separated by semicolons.

• Jep.continueParsing()

continueParsing

public Node continueParsing()
                     throws ParseException

Calls the MultipleEquationParser.continueParsing() method.

Overrides:

continueParsing in class Jep

Returns:

top node of equation parsed to date or null at EOF.

Throws:

ParseException - if there is a syntax error in expression
