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 EmptyOperatorTable

Returns:

a new Table
