A FilterIn is an IFilter that
checks membership of a given set of values in a table.
The membership is checked with a set of lookup expressions
in a LookupList that is set in
the FilterIn.

Finalize()() | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) | |
GetHashCode()() | Serves as a hash function for a particular type. GetHashCode()() is suitable for use in hashing algorithms and data structures like a hash table. (Inherited from Object.) | |
GetType()() | Gets the Type of the current instance. (Inherited from Object.) | |
LookupList |
Gets and sets the LookupList for this FilterIn.
| |
MemberwiseClone()() | Creates a shallow copy of the current Object. (Inherited from Object.) | |
TableName |
Gets and sets the table name for this FilterIn.
| |
ToString()() |
Returns the string form of this FilterIn.
(Overrides Object.ToString()().) | |

Returns the wire form of this FilterIn.
| |
ValidateSyntax()() |

Remarks
This filter:
is semantically correct if MyTable is GROUPED
by the same number of fields as the number of expressions within
brackets "[...]". In this way, the contents of the brackets
uniquely identify a record in MyTable. Brackets with
no expression list within represent access to a table that
is GROUPed to a single record.
CopyC#
"[<i>expression1</i>, <i>expression2</i>] IN MyTable"
Because the implicit tables NavStateRecords and AllBaseRecords are not GROUPED, it is not possible to do a lookup on these tables.
