CSensrvChannelCondition Class Reference

class CSensrvChannelCondition : public CBase

CSensrvChannelCondition represents a channel condition item. Channel conditions are added to a channel condition set. A channel condition set is met when all channel conditions are met at the same time, if it is AND-type set, or when single condition is met if it is OR-type set. Only one channel condition can be set for each data item in single channel condition set. Certain condition types (range conditions) require two condition objects (upper and lower limit) in a condition set for the set to be valid. The pair of conditions must both have the same index in the condition set and they are considered a single channel condition.

Each Condition has an ItemIndex associated with it. When a Condition is added to a Condition Set using CSensrvChannelConditionSet::AddChannelConditionL() this index must be different to all other conditions added to the set with the exception of range conditions as described above. If the index supplied already exists and the condition is not part of a range condition then CSensrvChannelConditionSet::AddChannelConditionL() leaves with KErrArgument.

Reference to condition value descriptor.

GetConditionValue(TDes8 &)

TInt GetConditionValue(TDes8 &aValue)const [pure virtual]

Get condition value.

KErrOverflow if aData is the wrong size for data item or one of the system-wide error codes

Parameters

IMPORT_C CSensrvChannelCondition *NewL(TIntaConditionType,
TIntaConditionOperator,
TIntaItemIndex,
TDesC8 &aValue
)[static]

Two-phase constructor

Pointer to created object

leave

KErrNoMemory

leave

KErrArgument if parameters are invalid or are less than 0

leave

One of the system-wide error codes

Parameters

TInt aConditionTypeDefines the type of the condition
TInt aConditionOperatorDefines the operator used in the condition
TInt aItemIndexItem index to be used in the condition evaluation
TDesC8 & aValueValue to be used in condition evaluation. By default this should be a packaged data object of the channel. See the channel specific headers in . If the channel type requires a different type of value, that must be indicated clearly in the channel specific header defining the channel.
