Member Functions Documentation

IsComplete()

IMPORT_C TBool

IsComplete

(

)

const

Checks that channel information in this object is complete. Complete means no zero or empty fields. Channel Id, Data Item Size and the Reserved fields are ignored.

Since: S60 5.0

IsMatch(const TSensrvChannelInfo &)

IMPORT_C TBool

IsMatch

(

const TSensrvChannelInfo &

aInfo

)

const

Checks if this instance matches supplied instance. Fields that are zero or empty are ignored. Channel Id, Data Item Size and Reserved fields are ignored.

Since: S60 5.0

Parameters

const TSensrvChannelInfo & aInfo

Instance to be matched against this instance.
