 com.mckoi.database.CorrelatedVariable
| CorrelatedVariable | | public class CorrelatedVariable implements Cloneable,java.io.Serializable(Code) | | A wrapper for a variable in a sub-query that references a column outside
of the current query. A correlated variable differs from a regular
variable because its value is constant in an operation, but may vary over
future iterations of the operation.
This object is NOT immutable.

| CorrelatedVariable | | public CorrelatedVariable(Variable variable, int level_offset)(Code) | | Constructs the CorrelatedVariable.
|
| getEvalResult | | public TObject getEvalResult()(Code) | | Returns the value this correlated variable evaluates to.
|
| getQueryLevelOffset | | public int getQueryLevelOffset()(Code) | | Returns the number of sub-query branches back that the reference for this
variable can be found. For example, if the correlated variable references
the direct descendant this will return 1.
