TcxCustomDataSource.IsNativeCompare Method
Specifies whether fast comparison operations are supported by the current data source.
Declaration
function IsNativeCompare: Boolean; virtual;
Returns
Type |
---|
Boolean |
Remarks
This function returns True if fast comparison operations are supported by a custom data source. In this instance, the GetInfoForCompare method provides direct access in memory to the value of a specific record/column.
If the function returns False, then values to compare are obtained via the GetValue method. This operation is more time consuming as it involves conversions of Variant types.
