public class DynamoDBMapper
extends AbstractDynamoDBMapper

Object mapper for domain-object interaction with DynamoDB.

To use, define a domain class that represents an item in a DynamoDB table and annotate it with the annotations found in the com.amazonaws.services.dynamodbv2.datamodeling package. In order to allow the mapper to correctly persist the data, each modeled property in the domain class should be accessible via getter and setter methods, and each property annotation should be either applied to the getter method or the class field. A minimal example using getter annotations:

 @DynamoDBTable(tableName = "TestTable")
 public class TestClass {

     private Long key;
     private double rangeKey;
     private Long version;

     private Set<Integer> integerSetAttribute;

     @DynamoDBHashKey
     public Long getKey() {
         return key;
     }

     public void setKey(Long key) {
         this.key = key;
     }

     @DynamoDBRangeKey
     public double getRangeKey() {
         return rangeKey;
     }

     public void setRangeKey(double rangeKey) {
         this.rangeKey = rangeKey;
     }

     @DynamoDBAttribute(attributeName = "integerSetAttribute")
     public Set<Integer> getIntegerAttribute() {
         return integerSetAttribute;
     }

     public void setIntegerAttribute(Set<Integer> integerAttribute) {
         this.integerSetAttribute = integerAttribute;
     }

     @DynamoDBVersionAttribute
     public Long getVersion() {
         return version;
     }

     public void setVersion(Long version) {
         this.version = version;
     }
 }

Save instances of annotated classes to DynamoDB, retrieve them, and delete them using the DynamoDBMapper class, as in the following example.

 DynamoDBMapper mapper = new DynamoDBMapper(dynamoDBClient);
 Long hashKey = 105L;
 double rangeKey = 1.0d;
 TestClass obj = mapper.load(TestClass.class, hashKey, rangeKey);
 obj.getIntegerAttribute().add(42);
 mapper.save(obj);
 mapper.delete(obj);

If you don't have your DynamoDB table set up yet, you can use generateCreateTableRequest(Class) to construct the CreateTableRequest for the table represented by your annotated class.

 AmazonDynamoDB dynamoDBClient = new AmazonDynamoDBClient();
 DynamoDBMapper mapper = new DynamoDBMapper(dynamoDBClient);
 CreateTableRequest req = mapper.generateCreateTableRequest(TestClass.class);
 // Table provision throughput is still required since it cannot be specified in your POJO
 req.setProvisionedThroughput(new ProvisionedThroughput(5L, 5L));
 // Fire off the CreateTableRequest using the low-level client
 dynamoDBClient.createTable(req);

When using the save, load, and delete methods, DynamoDBMapper will throw DynamoDBMappingExceptions to indicate that domain classes are incorrectly annotated or otherwise incompatible with this class. Service exceptions will always be propagated as AmazonClientException, and DynamoDB-specific subclasses such as ConditionalCheckFailedException will be used when possible.

This class is thread-safe and can be shared between threads. It's also very lightweight, so it doesn't need to be.

            DynamoDBMapperConfig config)
```
    Description copied from interface: IDynamoDBMapper
    Saves an item in DynamoDB. The service method used is determined by the DynamoDBMapperConfig.getSaveBehavior() value, to use either AmazonDynamoDB.putItem(PutItemRequest) or AmazonDynamoDB.updateItem(UpdateItemRequest):
    - UPDATE (default) : UPDATE will not affect unmodeled attributes on a save operation and a null value for the modeled attribute will remove it from that item in DynamoDB. Because of the limitation of updateItem request, the implementation of UPDATE will send a putItem request when a key-only object is being saved, and it will send another updateItem request if the given key(s) already exists in the table.
    - UPDATE_SKIP_NULL_ATTRIBUTES : Similar to UPDATE except that it ignores any null value attribute(s) and will NOT remove them from that item in DynamoDB. It also guarantees to send only one single updateItem request, no matter the object is key-only or not.
    - CLOBBER : CLOBBER will clear and replace all attributes, included unmodeled ones, (delete and recreate) on save. Versioned field constraints will also be disregarded.
    Any options specified in the saveExpression parameter will be overlaid on any constraints due to versioned attributes.
    Specified by:
    
    save in interface IDynamoDBMapper
    
    Overrides:
    
    save in class AbstractDynamoDBMapper
    
    Parameters:
    object - The object to save into DynamoDB
    saveExpression - The options to apply to this save request
    config - The configuration to use, which overrides the default provided at object construction.

```
    Description copied from interface: IDynamoDBMapper
    
    Scans through an Amazon DynamoDB table on logically partitioned segments in parallel. This method will create a thread pool of the specified size, and each thread will issue scan requests for its assigned segment, following the returned continuation token, until the end of its segment. Callers should be responsible for setting the appropriate number of total segments. More scan segments would result in better performance but more consumed capacity of the table. The results are returned in one unmodifiable list of instantiated objects. The table to scan is determined by looking at the annotations on the specified class, which declares where to store the object data in Amazon DynamoDB, and the scan expression parameter allows the caller to filter results and control how the scan is executed.
    Callers should be aware that the returned list is unmodifiable, and any attempts to modify the list will result in an UnsupportedOperationException.
    You can specify the pagination loading strategy for this parallel scan operation. By default, the list returned is lazily loaded when possible.

    Description copied from interface: IDynamoDBMapper
    
    Queries an Amazon DynamoDB table and returns the matching results as an unmodifiable list of instantiated objects. The table to query is determined by looking at the annotations on the specified class, which declares where to store the object data in Amazon DynamoDB, and the query expression parameter allows the caller to filter results and control how the query is executed.
    When the query is on any local/global secondary index, callers should be aware that the returned object(s) will only contain item attributes that are projected into the index. All the other unprojected attributes will be saved as type default values.
    Callers should also be aware that the returned list is unmodifiable, and any attempts to modify the list will result in an UnsupportedOperationException.
