Package com.singularsys.jep.walkers

Class ImportationVisitor

java.lang.Object

com.singularsys.jep.walkers.DoNothingVisitor

com.singularsys.jep.walkers.DeepCopyVisitor

com.singularsys.jep.walkers.ImportationVisitor

All Implemented Interfaces:

JepComponent, ParserVisitor, Serializable

public class ImportationVisitor
extends DeepCopyVisitor

Imports an expression from one Jep instance into another. This class is quicker than using a SerializableExpression but cannot handle such large equations.

   Jep sourceJep = ...;
   Jep destJep = ...;
   ImportationVisitor iv = new ImportationVisitor(destJep);
   Node node = sourceJep.parse("x^2-y^2");
   Node imported = iv.deepCopy(node); 
 

Since:

Jep 3.5
