Copy constructor
S60 5.0
| const TSensrvChannelInfo & aChannelInfo | Instance to be copied |
| 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.
S60 5.0
ETrue if channel information is complete.
| 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.
S60 5.0
ETrue if there is a match, otherwise EFalse
| const TSensrvChannelInfo & aInfo | Instance to be matched against this instance. |
| TSensrvChannelDataTypeId | iChannelDataTypeId |
Identifies the channel data type. This value is a uid and is unique among all channels. See sensor channel specific header files.
| TSensrvChannelTypeId | iChannelType |
Channel type identifier
Identifies the channel type and therefore the content of the channel. This value is a uid and is unique among all channels. See sensor channel specific header files.
| TBuf8< KSensrvLocationLength > | iLocation |
Location of the of the channel. This is a free format string
| TBuf8< KSensrvVendorIdLength > | iVendorId |
Vendor name of the channel provider. This is a free format string and is not to be confused with Vendor Id unique Uid's.
