IsEqual(const MHashKey &)

TBool

IsEqual

(

const MHashKey &

aKey

)

[pure virtual]

Return ETrue if this key is considered equal to the another key. Equality can be a non-trivial concept, as can be seen in the implementation of THashKeyIp6 that implements this virtual class.

Parameters

const MHashKey & aKey

ToInt()

TUint

ToInt

(

)

[pure virtual]

Generate a unsigned integer value from the key. It can be used, e.g. as an index to the hash table. The integer generation must be deterministic.
