Member Function Documentation

virtual DtBaseHashKey* DtBaseHashKey::clone

(

)

const [pure virtual]

Make a copy of this hash key.

Implemented in DtWStringHashKey, DtStringHashKey, DtPtrHashKey, DtIntHashKey, DtObjectIdHashKey, DtEntityIdentifierHashKey, and DtSystemHashKey.

virtual DtU32 DtBaseHashKey::computeHashValue

(

)

[protected, pure virtual]

Compute the hashed value for this key.

Implemented in DtWStringHashKey, DtStringHashKey, DtPtrHashKey, DtIntHashKey, DtObjectIdHashKey, DtEntityIdentifierHashKey, and DtSystemHashKey.

virtual bool DtBaseHashKey::equalTo

(

const DtBaseHashKey &

otherKey

)

const [virtual]

Subclasses may override this to provide an optimized comparison between two keys.

Base implementation calls operator== which uses strings to compare.

Reimplemented in DtPtrHashKey, and DtIntHashKey.

virtual DtU32 DtBaseHashKey::hashValue

(

)

const [virtual]

Get the hashed value for this key.

This may modify myHashValueIsComputed and myHashValue

virtual bool DtBaseHashKey::operator!=

(

const DtBaseHashKey &

other

)

const [virtual]

equality operator

DtBaseHashKey& DtBaseHashKey::operator=

(

const DtBaseHashKey &

orig

)

assignment operator

virtual bool DtBaseHashKey::operator==

(

const DtBaseHashKey &

other

)

const [virtual]

equality operator

Reimplemented in DtObjectIdHashKey, and DtEntityIdentifierHashKey.

virtual const DtString DtBaseHashKey::stringRep

(

)

const [pure virtual]

Get the string representation of this key.

Implemented in DtWStringHashKey, DtStringHashKey, DtPtrHashKey, DtIntHashKey, DtObjectIdHashKey, DtEntityIdentifierHashKey, and DtSystemHashKey.
