## Enum OperatorId

- java.lang.Object
- - java.lang.Enum<OperatorId>
  - - com.smartgwt.client.types.OperatorId

- All Implemented Interfaces:
    ValueEnum, java.io.Serializable, java.lang.Comparable<OperatorId>

      public enum OperatorId
      extends java.lang.Enum<OperatorId>
      implements ValueEnum

  An operator is used as part of a `Criterion` when specifying `AdvancedCriteria`.

  This list of operators indicates the set of operators built into Smart GWT DataSources, which can be used for both client and server-side filtering. Some operators offer case-insensitive versions, prefixed with a lower-case i, such as `iContains`. Note that such operators are intended for text-based searches and are not available to numeric or date fields (integer/float/date/datetime and derivatives), where there is no use for case.

  You can extend the list of operators with `DataSource.addSearchOperator()`.
