* <p>Represents a condition to be compared with an attribute value. This condition
* can be used with <code>DeleteItem</code>, <code>PutItem</code>, or
* <code>UpdateItem</code> operations; if the comparison evaluates to true, the
* operation succeeds; if not, the operation fails. You can use
* <code>ExpectedAttributeValue</code> in one of two different ways:</p> <ul> <li>
* <p>Use <code>AttributeValueList</code> to specify one or more values to compare
* against an attribute. Use <code>ComparisonOperator</code> to specify how you
* want to perform the comparison. If the comparison evaluates to true, then the
* conditional operation succeeds.</p> </li> <li> <p>Use <code>Value</code> to
* specify a value that DynamoDB will compare against an attribute. If the values
* match, then <code>ExpectedAttributeValue</code> evaluates to true and the
* conditional operation succeeds. Optionally, you can also set <code>Exists</code>
* to false, indicating that you <i>do not</i> expect to find the attribute value
* in the table. In this case, the conditional operation succeeds only if the
* comparison evaluates to false.</p> </li> </ul> <p> <code>Value</code> and
* <code>Exists</code> are incompatible with <code>AttributeValueList</code> and

* does not equal <code>{"N":"6"}</code>. Also, <code>{"N":"6"}</code> does not
* compare to <code>{"NS":["6", "2", "1"]}</code>.</p> <p/> </li> <li> <p>
* <code>NOT_NULL</code> : The attribute exists. <code>NOT_NULL</code> is supported
* for all data types, including lists and maps.</p> <p>This operator tests
* for the existence of an attribute, not its data type. If the data type of
* attribute "<code>a</code>" is null, and you evaluate it using
* <code>NOT_NULL</code>, the result is a Boolean <code>true</code>. This result is
* because the attribute "<code>a</code>" exists; its data type is not relevant to
* the <code>NOT_NULL</code> comparison operator.</p> </li> <li> <p>
* <code>NULL</code> : The attribute does not exist. <code>NULL</code> is supported
* for all data types, including lists and maps.</p> <p>This operator tests
* for the nonexistence of an attribute, not its data type. If the data type of
* attribute "<code>a</code>" is null, and you evaluate it using <code>NULL</code>,
* the result is a Boolean <code>false</code>. This is because the attribute
* "<code>a</code>" exists; its data type is not relevant to the <code>NULL</code>
* comparison operator.</p> </li> <li> <p> <code>CONTAINS</code> : Checks
* for a subsequence, or value in a set.</p> <p> <code>AttributeValueList</code>
* can contain only one <code>AttributeValue</code> element of type String, Number,
* or Binary (not a set type). If the target attribute of the comparison is of type
* String, then the operator checks for a substring match. If the target attribute
* of the comparison is of type Binary, then the operator looks for a subsequence
* of the target that matches the input. If the target attribute of the comparison
* is a set ("<code>SS</code>", "<code>NS</code>", or "<code>BS</code>"), then the
* operator evaluates to true if it finds an exact match with any member of the
* set.</p> <p>CONTAINS is supported for lists: When evaluating "<code>a CONTAINS
* b</code>", "<code>a</code>" can be a list; however, "<code>b</code>" cannot be a
* set, a map, or a list.</p> </li> <li> <p> <code>NOT_CONTAINS</code> : Checks for
* absence of a subsequence, or absence of a value in a set.</p> <p>
* <code>AttributeValueList</code> can contain only one <code>AttributeValue</code>
* element of type String, Number, or Binary (not a set type). If the target
* attribute of the comparison is a String, then the operator checks for the
* absence of a substring match. If the target attribute of the comparison is
* Binary, then the operator checks for the absence of a subsequence of the target
* that matches the input. If the target attribute of the comparison is a set
* ("<code>SS</code>", "<code>NS</code>", or "<code>BS</code>"), then the operator
* evaluates to true if it <i>does not</i> find an exact match with any member of
* the set.</p> <p>NOT_CONTAINS is supported for lists: When evaluating "<code>a
* NOT CONTAINS b</code>", "<code>a</code>" can be a list; however,
* "<code>b</code>" cannot be a set, a map, or a list.</p> </li> <li> <p>
* <code>BEGINS_WITH</code> : Checks for a prefix. </p> <p>
* <code>AttributeValueList</code> can contain only one <code>AttributeValue</code>
* of type String or Binary (not a Number or a set type). The target attribute of
* the comparison must be of type String or Binary (not a Number or a set
* type).</p> <p/> </li> <li> <p> <code>IN</code> : Checks for matching elements in
* a list.</p> <p> <code>AttributeValueList</code> can contain one or more
* <code>AttributeValue</code> elements of type String, Number, or Binary. These
* attributes are compared against an existing attribute of an item. If any
* elements of the input are equal to the item attribute, the expression evaluates
* to true.</p> </li> <li> <p> <code>BETWEEN</code> : Greater than or equal to the
* first value, and less than or equal to the second value. </p> <p>
* <code>AttributeValueList</code> must contain two <code>AttributeValue</code>
* elements of the same type, either String, Number, or Binary (not a set type). A
* target attribute matches if the target value is greater than, or equal to, the
* first element and less than, or equal to, the second element. If an item
* contains an <code>AttributeValue</code> element of a different type than the one
* provided in the request, the value does not match. For example,
* <code>{"S":"6"}</code> does not compare to <code>{"N":"6"}</code>. Also,
* <code>{"N":"6"}</code> does not compare to <code>{"NS":["6", "2", "1"]}</code>
