Member Function Documentation

coefficient()

double EntryKeyDataBool::coefficient ( const EntryKeyData *  data1, const EntryKeyData *  data2  ) const

virtual

Cannot be called for EntryKeyDataBool.

Booleans cannot be compared with greater of smaller and no coefficient can be counted.

Parameters

data1	Nothing.
data2	Nothing.

Returns

Nothing

Exceptions

WrongSubclass

Given data type was illegal.

Implements EntryKeyData.

Definition at line 573 of file EntryKeyData.cc.

                                                                            {
    throw WrongSubclass(__FILE__, __LINE__,
                        "EntryKeyDataBool::coefficient");
    return 0.0; // stupid return statement to keep compiler quiet
}

copy()

EntryKeyData * EntryKeyDataBool::copy ( ) const

virtual

Copies the boolean.

Client is responsible of deallocating the memory reserved for the returned object.

Returns

A copy of the boolean.

Implements EntryKeyData.

Definition at line 507 of file EntryKeyData.cc.

                             {
    return new EntryKeyDataBool(data_);
}

Here is the call graph for this function:

isEqual()

bool EntryKeyDataBool::isEqual ( const EntryKeyData *  fieldData ) const

virtual

Checks if two booleans are equal.

Cannot compare to other data types.

Parameters

fieldData

Boolean.

Returns

True if two booleans are equal.

Exceptions

WrongSubclass

Given data type was illegal.

Implements EntryKeyData.

Definition at line 521 of file EntryKeyData.cc.

                                                             {
    EntryKeyDataBool* data = dynamic_cast<EntryKeyDataBool*>(
        const_cast<EntryKeyData*>(fieldData));

isGreater()

bool EntryKeyDataBool::isGreater ( const EntryKeyData *  fieldData ) const

virtual

Checks if another operation set is greater.

Cannot compare to other data types. You cannot say which is greater in case of booleans and false is returned always.

Parameters

fieldData

Boolen.

Returns

Always false.

Exceptions

WrongSubclass

Given data type was illegal.

Implements EntryKeyData.

Definition at line 542 of file EntryKeyData.cc.

                                                     {
    return false;
}

isSmaller()

bool EntryKeyDataBool::isSmaller ( const EntryKeyData *  fieldData ) const

virtual

Checks if this operation set is smaller than another set.

Cannot compare to other data types. You cannot say which is greater in case of booleans and true is returned always.

Parameters

fieldData

Boolean.

Returns

Always true.

Exceptions

WrongSubclass

Given data type was illegal.

Implements EntryKeyData.

Definition at line 557 of file EntryKeyData.cc.

                                                     {
    return true;
}

operator=()

EntryKeyDataBool& EntryKeyDataBool::operator= ( const EntryKeyDataBool &  )

private

Assignment not allowed.

toString()

std::string EntryKeyDataBool::toString ( ) const

virtual

Converts the boolean into a string.

Returns

Boolean as a string.
