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, DtIFFSystemHashKey, and DtSystemHashKey.

virtual DtU64 DtBaseHashKey::computeHashValue ( )

protectedpure virtual

Compute the hashed value for this key.

Implemented in DtWStringHashKey, DtStringHashKey, DtPtrHashKey, DtIntHashKey, DtIFFSystemHashKey, 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 DtHashKeyType DtBaseHashKey::hashKeyType ( ) const

inlinevirtual

Get the type of HashKey.

Reimplemented in DtWStringHashKey, DtStringHashKey, DtPtrHashKey, DtIntHashKey, DtObjectIdHashKey, DtEntityIdentifierHashKey, DtIFFSystemHashKey, and DtSystemHashKey.
