Instance Attribute Details
#b ⇒ String
An attribute of type Binary. For example:
"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"
#bool ⇒ Boolean
An attribute of type Boolean. For example:
"BOOL": true
#bs ⇒ Array<String>
An attribute of type Binary Set. For example:
"BS": ["U3Vubnk=", "UmFpbnk=", "U25vd3k="]
#l ⇒ Array<Types::AttributeValue>
An attribute of type List. For example:
"L": [ {"S": "Cookies"} , {"S": "Coffee"}, {"N", "3.14159"}]
#m ⇒ Hash<String,Types::AttributeValue>
An attribute of type Map. For example:
"M": {"Name": {"S": "Joe"}, "Age": {"N": "35"}}
#n ⇒ String
An attribute of type Number. For example:
"N": "123.45"
Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.
#ns ⇒ Array<String>
An attribute of type Number Set. For example:
"NS": ["42.2", "-19", "7.5", "3.14"]
Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.
#null ⇒ Boolean
An attribute of type Null. For example:
"NULL": true
#s ⇒ String
An attribute of type String. For example:
"S": "Hello"
#ss ⇒ Array<String>
An attribute of type String Set. For example:
"SS": ["Giraffe", "Hippo" ,"Zebra"]
