All Implemented Interfaces:: Serializable, SdkPojo, ToCopyableBuilder<Condition.Builder,Condition>

@Generated("software.amazon.awssdk:codegen") public final class Condition extends Object implements SdkPojo, Serializable, ToCopyableBuilder<Condition.Builder,Condition>

Represents the selection criteria for a Query or Scan operation:

For a Query operation, Condition is used for specifying the KeyConditions to use when querying a table or an index. For KeyConditions, only the following comparison operators are supported:

EQ | LE | LT | GE | GT | BEGINS_WITH | BETWEEN

Condition is also used in a QueryFilter, which evaluates the query results and returns only the desired values.
For a Scan operation, Condition is used in a ScanFilter, which evaluates the scan results and returns only the desired values.

Method Details
- hasAttributeValueList
  
  public final boolean hasAttributeValueList()
  
  For responses, this returns true if the service returned a value for the AttributeValueList property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
- attributeValueList
  
  public final List<AttributeValue> attributeValueList()
  
  One or more values to evaluate against the supplied attribute. The number of values in the list depends on the ComparisonOperator being used.
  
  For type Number, value comparisons are numeric.
  
  String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than B. For a list of code values, see http://en.wikipedia .org/wiki/ASCII#ASCII_printable_characters.
  
  For Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.
  
  Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
  
  This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAttributeValueList() method.
  
  Returns:
  
  One or more values to evaluate against the supplied attribute. The number of values in the list depends on the ComparisonOperator being used.
  
  For type Number, value comparisons are numeric.
  
  String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than B. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.
  
  For Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.
- comparisonOperator
  public final ComparisonOperator comparisonOperator()
  
  A comparator for evaluating attributes. For example, equals, greater than, less than, etc.
  
  The following comparison operators are available:
  
  EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN
  
  The following are descriptions of each comparison operator.
  
  EQ : Equal. EQ is supported for all data types, including lists and maps.
  
  AttributeValueList can contain only one AttributeValue element of type String, Number, Binary, String Set, Number Set, or Binary Set. If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]}.
  
  NE : Not equal. NE is supported for all data types, including lists and maps.
  
  AttributeValueList can contain only one AttributeValue of type String, Number, Binary, String Set, Number Set, or Binary Set. If an item contains an AttributeValue of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]}.
  
  LE : Less than or equal.
  
  AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.
  
  LT : Less than.
  
  AttributeValueList can contain only one AttributeValue of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.
  
  GE : Greater than or equal.

If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.
  
  GT : Greater than.
  
  AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.
  
  NOT_NULL : The attribute exists. NOT_NULL is supported for all data types, including lists and maps.
  
  This operator tests for the existence of an attribute, not its data type. If the data type of attribute " a" is null, and you evaluate it using NOT_NULL, the result is a Boolean true. This result is because the attribute "a" exists; its data type is not relevant to the NOT_NULL comparison operator.
  
  NULL : The attribute does not exist. NULL is supported for all data types, including lists and maps.
  
  This operator tests for the nonexistence of an attribute, not its data type. If the data type of attribute " a" is null, and you evaluate it using NULL, the result is a Boolean false. This is because the attribute "a" exists; its data type is not relevant to the NULL comparison operator.
  
  CONTAINS : Checks for a subsequence, or value in a set.
  
  AttributeValueList can contain only one AttributeValue 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 (" SS", "NS", or "BS"), then the operator evaluates to true if it finds an exact match with any member of the set.
  
  CONTAINS is supported for lists: When evaluating "a CONTAINS b", "a " can be a list; however, "b" cannot be a set, a map, or a list.
  
  NOT_CONTAINS : Checks for absence of a subsequence, or absence of a value in a set.
  
  AttributeValueList can contain only one AttributeValue 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 ("SS", "NS", or "BS"), then the operator evaluates to true if it does not find an exact match with any member of the set.
  
  NOT_CONTAINS is supported for lists: When evaluating "a NOT CONTAINS b", "a " can be a list; however, "b" cannot be a set, a map, or a list.
  
  BEGINS_WITH : Checks for a prefix.
  
  AttributeValueList can contain only one AttributeValue 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).
  
  IN : Checks for matching elements in a list.
  
  AttributeValueList can contain one or more AttributeValue 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.
  
  BETWEEN : Greater than or equal to the first value, and less than or equal to the second value.
  
  AttributeValueList must contain two AttributeValue 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 AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not compare to {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}
  
  For usage examples of AttributeValueList and ComparisonOperator, see Legacy Conditional Parameters in the Amazon DynamoDB Developer Guide.
  
  If the service returns an enum value that is not available in the current SDK version, comparisonOperator will return ComparisonOperator.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from comparisonOperatorAsString().
  
  Returns:
  
  A comparator for evaluating attributes. For example, equals, greater than, less than, etc.

  Description copied from interface: SdkPojo
  
  Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.
  If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.
  
  Specified by:
  
  equalsBySdkFields in interface SdkPojo
  
  Parameters:
  
  obj - the object to be compared with
  
  Returns:
  
  true if the other object equals to this object by sdk fields, false otherwise.
- toString
  
  public final String toString()
  
  Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
  
  Overrides:
