le
Returns a comparator condition (that evaluates to true if the value of the current attribute is less than or equal to the specified value) for building condition expression. -
le
Returns a comparator condition (that evaluates to true if the value of the current attribute is less than or equal to that of the specified attribute) for building condition expression. -
lt
Returns a comparator condition (that evaluates to true if the value of the current attribute is less than the specified value) for building condition expression. -
lt

between
Returns aBetweenCondition
that represents a BETWEEN comparison (that evaluates to true if the value of the current attribute is greater than or equal to the given low value, and less than or equal to the given high value) for building condition expression. -
ifNotExists
Returns anIfNotExists
object which represents an if_not_exists(path, operand) function call where path refers to that of the current attribute; used for building expressions."if_not_exists (path, operand) – If the item does not contain an attribute at the specified path, then if_not_exists evaluates to operand; otherwise, it evaluates to path. You can use this function to avoid overwriting an attribute already present in the item."
- Parameters:
defaultValue
- the default value that will be used as the operand to the if_not_exists function call.
-
in
Returns an InCondition (that evaluates to true if the value of the current attribute is equal to any of the specified values) for building condition expression.- Parameters:
values
- specified values. The number of values must be at least one and at most 100.
-
in
Returns an InCondition (that evaluates to true if the value of the current attribute is equal to any of the values in the specified list) for building condition expression.- Parameters:
values
- specified list of values. The number of values must be at least one and at most 100.
-
set
Returns aSetAction
object used for building update expression. If the attribute referred to by this path operand doesn't exist, the returned object represents adding the attribute value of the specified source path operand to an item. If the current attribute already exists, the returned object represents the value replacement of the current attribute by the attribute value of the specified source path operand. -
set
Returns aSetAction
object used for building update expression. If the attribute referred to by this path operand doesn't exist, the returned object represents adding the specified value as an attribute to an item. If the attribute referred to by this path operand already exists, the returned object represents the value replacement of the current attribute by the specified value. -
set
Returns aSetAction
object used for building update expression. If the attribute referred to by this path operand doesn't exist, the returned object represents adding the value of evaluating the specifiedIfNotExists
function as an attribute to an item. If the attribute referred to by this path operand already exists, the returned object represents the value replacement of the current attribute by the value of evaluating the specifiedIfNotExists
function. -
eq
Returns a comparator condition (that evaluates to true if the attribute value referred to by this path operand is equal to the specified value) for building condition expression. -
ne
Returns a comparator condition (that evaluates to true if the attribute value referred to by this path operand is not equal to that of the specified path operand) for building condition expression. -
ifNotExists
Returns anIfNotExists
object which represents an if_not_exists(path, operand) function call where path refers to that of the current path operand; used for building expressions."if_not_exists (path, operand) – If the item does not contain an attribute at the specified path, then if_not_exists evaluates to operand; otherwise, it evaluates to path. You can use this function to avoid overwriting an attribute already present in the item."
- Parameters:
defaultValue
- the default value that will be used as the operand to the if_not_exists function call.
