@Generated(value="software.amazon.awssdk:codegen") public final class AttributeValue extends Object implements SdkPojo, Serializable, ToCopyableBuilder<AttributeValue.Builder,AttributeValue>
Represents the data for an attribute.
Each attribute value is described as a name-value pair. The name is the data type, and the value is the data itself.

public final String s()
An attribute of type String. For example:
"S": "Hello"
"S": "Hello"
public final String n()
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.

public final SdkBytes b()
An attribute of type Binary. For example:
"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"
"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"
public final boolean hasSs()
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.public final List<String> ss()
An attribute of type String Set. For example:
"SS": ["Giraffe", "Hippo" ,"Zebra"]
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 hasSs()
method.
"SS": ["Giraffe", "Hippo" ,"Zebra"]
public final boolean hasNs()
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.public final List<String> ns()
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.
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 hasNs()
method.
"NS": ["42.2", "-19", "7.5", "3.14"]

public final boolean hasBs()
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.public final List<SdkBytes> bs()
An attribute of type Binary Set. For example:
"BS": ["U3Vubnk=", "UmFpbnk=", "U25vd3k="]
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 hasBs()
method.
"BS": ["U3Vubnk=", "UmFpbnk=", "U25vd3k="]
public final boolean hasM()
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.public final Map<String,AttributeValue> m()
An attribute of type Map. For example:
"M": {"Name": {"S": "Joe"}, "Age": {"N": "35"}}
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 hasM()
method.
"M": {"Name": {"S": "Joe"}, "Age": {"N": "35"}}
public final boolean hasL()
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.public final List<AttributeValue> l()
An attribute of type List. For example:
"L": [ {"S": "Cookies"} , {"S": "Coffee"}, {"N", "3.14159"}]
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 hasL()
method.
"L": [ {"S": "Cookies"} , {"S": "Coffee"}, {"N", "3.14159"}]
public final Boolean bool()
An attribute of type Boolean. For example:
"BOOL": true
"BOOL": true
public final Boolean nul()
An attribute of type Null. For example:
"NULL": true
"NULL": true
