Method Detail

setBasicPfmcs

protected void setBasicPfmcs()

Description copied from class: StandardOperatorTable2

Sets the standard set of pfmc's for basic operators. This method is called by the constructor and subclasses can override this method to change or prevent building of these pfmcs.

Overrides:

setBasicPfmcs in class FieldOperatorTable

See Also:

OperatorTable2.BasicOperators

setSpecialPfmcs

protected void setSpecialPfmcs()

Description copied from class: FieldOperatorTable

Does nothing, prevents parents method being called in copy constructor.

Overrides:

setSpecialPfmcs in class FieldOperatorTable

See Also:

OperatorTable2.SpecialOperators

setMatrixPfmcs

protected void setMatrixPfmcs()

Sets the pfmc's for basic and special operators. Called by the constructor.

getMatrixField

public MatrixFieldI getMatrixField()

getMatrixFactory

public MatrixFactoryI getMatrixFactory()

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 FieldOperatorTable

Returns:

a new Table
