Method Detail

values

public static InternalUtils[] values()

Deprecated.

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (InternalUtils c : InternalUtils.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static InternalUtils valueOf(String name)

Deprecated.

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

toItemList

public static List<Item> toItemList(List<Map<String,AttributeValue>> items)

Deprecated.

Returns a non-null list of Item's given the low level list of item information.

toAttributeValues

public static Map<String,AttributeValue> toAttributeValues(Item item)

Deprecated.

Converts an Item into the low-level representation; or null if the input is null.

fromSimpleMap

public static Map<String,AttributeValue> fromSimpleMap(Map<String,Object> map)

Deprecated.

Converts a map of string to simple objects into the low-level representation; or null if the input is null.

toAttributeValueUpdate

public static Map<String,AttributeValueUpdate> toAttributeValueUpdate(List<AttributeUpdate> attributesToUpdate)

Deprecated.

Converts a list of AttributeUpdate into the low-level representation; or null if the input is null.

toAttributeValue

public static AttributeValue toAttributeValue(Object value)

Deprecated.

Converts a simple value into the low-level representation.

Parameters:

value - the given value which can be one of the followings:

• String
• Set<String>
• Number (including any subtypes and primitive types)
• Set<Number>
• byte[]
• Set<byte[]>
• ByteBuffer
• Set<ByteBuffer>
• Boolean or boolean
• null
• Map<String,T>, where T can be any type on this list but must not induce any circular reference
• List<T>, where T can be any type on this list but must not induce any circular reference

Returns:

a non-null low level representation of the input object value

Throws:

UnsupportedOperationException - if the input object type is not supported

toSimpleList

public static List<Object> toSimpleList(List<AttributeValue> attrValues)

Deprecated.

Converts a list of low-level AttributeValue into a list of simple values. Each value in the returned list can be one of the followings:

• Set<Number>
• byte[]
• Set<byte[]>
• ByteBuffer
• Set<ByteBuffer>
• Boolean or boolean
• null
• Map<String,T>, where T can be any type on this list but must not induce any circular reference
