IVariableResolver Deveel.Data.Sql.Tables.FunctionTable.TableGroupResolver.GetVariableResolver ( int  setIndex )

inline

Returns a IVariableResolver that can be used to resolve variable in the get set of the group.

Parameters

setIndex

The object returned is undefined after the next call to this method.

Returns

Implements Deveel.Data.Sql.IGroupResolver.

DataObject Deveel.Data.Sql.Tables.FunctionTable.TableGroupResolver.Resolve ( ObjectName  variable, int  setIndex  )

inline

Returns the value of a variable of a group.

Parameters

variable
setIndex

The set index signifies the set item of the group. For example, if the group contains 10 items, then set_index may be between 0 and 9. Return types must be either a String, BigDecimal or Boolean.
