 package com.amazonaws.services.dynamodbv2.model;
 

Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.

A KeySchemaElement represents exactly one attribute of the primary key. For example, a hash type primary key would be represented by one KeySchemaElement . A hash-and-range type primary key would require one KeySchemaElement for the hash attribute, and another KeySchemaElement for the range attribute.

 
 public class KeySchemaElement implements SerializableCloneable {

    
The name of a key attribute.

Constraints:
Length: 1 - 255

 
     private String attributeName;

    
The attribute data, consisting of the data type and the attribute value itself.

Constraints:
Allowed Values: HASH, RANGE

 
     private String keyType;

    
Default constructor for a new KeySchemaElement object. Callers should use the setter or fluent setter (with...) methods to initialize this object after creating it.
 
     public KeySchemaElement() {}
    
    
Constructs a new KeySchemaElement object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.

Parameters:
attributeName The name of a key attribute.
keyType The attribute data, consisting of the data type and the attribute value itself.
 
     public KeySchemaElement(String attributeNameString keyType) {
         setAttributeName(attributeName);
         setKeyType(keyType);
     }

    
Constructs a new KeySchemaElement object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.

Parameters:
attributeName The name of a key attribute.
keyType The attribute data, consisting of the data type and the attribute value itself.
