public class ExtendedOperatorSet
extends StandardOperatorTable2

An example of an OperatorSet which adds two suffix operators: n! (factorial) and n% (percentage).

Since 3.5 the ternary conditional has been removed as this is already part of the JavaOperatorSet. The Factorial function has been moved from an inner class to its own class Factorial.

shallowCopy

public OperatorTableI shallowCopy()

Description copied from class: EmptyOperatorTable

Create a new version of this OperatorTable. Operators are copied into new table. However, Operators whose pfmc implement JepComponent are duplicated. This means the table could be used in a separate thread without problem. Subclasses should override with method to return a table of the correct type, a typical implementation would be

    @Override
    public OperatorTableI shallowCopy() {
        Map<OperatorKey, Operator> map = this.threadSafeMapCopy();
        return new MyOperatorTable(map);
    }
 

using the EmptyOperatorTable.threadSafeMapCopy() method to return a copy of the map of operators and a constructor taking this map which uses the EmptyOperatorTable(Map) constructor.

Specified by:

shallowCopy in interface OperatorTableI

Overrides:

shallowCopy in class StandardOperatorTable2

Returns:

a new Table
