public void setOperator(String operator) {
        this.operator = operator;
    }
<p>
The comparison operator that you want to use as a filter, for example <code>"Operator": "StringEquals"</code>.
Valid values are <code>"StringEquals"</code> and <code>"StringLike"</code>.
</p>
<p>
If you set the operator value to <code>"StringEquals"</code>, you need to provide an ownership related filter in
the <code>"NAME"</code> field and the arn of the user or group whose folders you want to search in the
<code>"Value"</code> field. For example,
<code>"Name":"DIRECT_QUICKSIGHT_OWNER", "Operator": "StringEquals", "Value": "arn:aws:quicksight:us-east-1:1:user/default/UserName1"</code>
.
</p>
<p>
If you set the value to <code>"StringLike"</code>, you need to provide the name of the folders you are searching
for. For example, <code>"Name":"FOLDER_NAME", "Operator": "StringLike", "Value": "Test"</code>. The
<code>"StringLike"</code> operator only supports the <code>NAME</code> value <code>FOLDER_NAME</code>.
