Field Detail

field

protected FieldI field

Constructor Detail

FieldOperatorTable

public FieldOperatorTable(FieldI field)

Constructor with a single field

Parameters:

field - field

FieldOperatorTable

public FieldOperatorTable(OperatorTable2 oldTable,
                          FieldI f)

Decorator constructor. Will use the field for the basic operators,

Parameters:

oldTable - base operator table

f - field

FieldOperatorTable

protected FieldOperatorTable(FieldI f,
                             java.util.Map<EmptyOperatorTable.OperatorKey,Operator> map)

Method Detail

setSpecialPfmcs

protected void setSpecialPfmcs()

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

Overrides:

setSpecialPfmcs in class StandardOperatorTable2

See Also:

OperatorTable2.SpecialOperators

setPsudoPfmcs

protected void setPsudoPfmcs()

Does nothing.

Overrides:

setPsudoPfmcs in class StandardOperatorTable2

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 StandardOperatorTable2

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
