## Methods

### getFilter()

    public abstract String getFilter()

Filter expression to restrict the `Registration`s returned.

The expression must specify the field name, a comparison operator, and the
value that you want to use for filtering. The value must be a string, a
number, a boolean, or an enum value. The comparison operator should be one
of =, !=, \>, \<, \>=, \<=, or : for prefix or wildcard matches.

For example, to filter to a specific domain name, use an expression like
`domainName="example.com"`. You can also check for the existence of a
field; for example, to find domains using custom DNS settings, use an
expression like `dnsSettings.customDns:*`.

You can also create compound filters by combining expressions with the
`AND` and `OR` operators. For example, to find domains that are suspended
or have specific issues flagged, use an expression like
`(state=SUSPENDED) OR (issue:*)`.

`string filter = 4;`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://docs.oracle.com/javase/8/docs/api/java/lang/String.html` | The filter. |

### getFilterBytes()

    public abstract ByteString getFilterBytes()

Filter expression to restrict the `Registration`s returned.

The expression must specify the field name, a comparison operator, and the
value that you want to use for filtering. The value must be a string, a
number, a boolean, or an enum value. The comparison operator should be one
of =, !=, \>, \<, \>=, \<=, or : for prefix or wildcard matches.
