  - getAttributesToGet
```
public List<String> getAttributesToGet()
```
    This is a legacy parameter, for backward compatibility. New applications should use ProjectionExpression instead. Do not combine legacy parameters and expression parameters in a single API call; otherwise, DynamoDB will return a ValidationException exception.
    
    This parameter allows you to retrieve attributes of type List or Map; however, it cannot retrieve individual elements within a List or a Map.
    
    The names of one or more attributes to retrieve. If no attribute names are provided, then all attributes will be returned. If any of the requested attributes are not found, they will not appear in the result.
    
    Note that AttributesToGet has no effect on provisioned throughput consumption. DynamoDB determines capacity units consumed based on item size, not on the amount of data that is returned to an application.
    
    Returns:

  setLimit
  
  public void setLimit(Integer limit)
  
  The maximum number of items to evaluate (not necessarily the number of matching items). If DynamoDB processes the number of items up to the limit while processing the results, it stops the operation and returns the matching values up to that point, and a key in LastEvaluatedKey to apply in a subsequent operation, so that you can pick up where you left off. Also, if the processed data set size exceeds 1 MB before DynamoDB reaches this limit, it stops the operation and returns the matching values up to the limit, and a key in LastEvaluatedKey to apply in a subsequent operation to continue the operation. For more information, see Query and Scan in the Amazon DynamoDB Developer Guide.
  
  Parameters:
  limit - The maximum number of items to evaluate (not necessarily the number of matching items). If DynamoDB processes the number of items up to the limit while processing the results, it stops the operation and returns the matching values up to that point, and a key in LastEvaluatedKey to apply in a subsequent operation, so that you can pick up where you left off. Also, if the processed data set size exceeds 1 MB before DynamoDB reaches this limit, it stops the operation and returns the matching values up to the limit, and a key in LastEvaluatedKey to apply in a subsequent operation to continue the operation.

  getScanFilter
  
  public Map<String,Condition> getScanFilter()
  
  This is a legacy parameter, for backward compatibility. New applications should use FilterExpression instead. Do not combine legacy parameters and expression parameters in a single API call; otherwise, DynamoDB will return a ValidationException exception.
  
  A condition that evaluates the scan results and returns only the desired values.
  
  This parameter does not support attributes of type List or Map.
  
  If you specify more than one condition in the ScanFilter map, then by default all of the conditions must evaluate to true. In other words, the conditions are ANDed together. (You can use the ConditionalOperator parameter to OR the conditions instead. If you do this, then at least one of the conditions must evaluate to true, rather than all of them.)
  
  Each ScanFilter element consists of an attribute name to compare, along with the following:
  
  AttributeValueList - One or more values to evaluate against the supplied attribute. The number of values in the list depends on the operator specified in ComparisonOperator .
  
  For type Number, value comparisons are numeric.
  
  String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than B. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.
  
  For Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.
  
  For information on specifying data types in JSON, see JSON Data Format in the Amazon DynamoDB Developer Guide.
  
  ComparisonOperator - A comparator for evaluating attributes. For example, equals, greater than, less than, etc.
  
  The following comparison operators are available:
  
  EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN
  
  For complete descriptions of all comparison operators, see Condition.
  
  Returns:

  A condition that evaluates the scan results and returns only the desired values.
  
  This parameter does not support attributes of type List or Map.
  
  If you specify more than one condition in the ScanFilter map, then by default all of the conditions must evaluate to true. In other words, the conditions are ANDed together. (You can use the ConditionalOperator parameter to OR the conditions instead. If you do this, then at least one of the conditions must evaluate to true, rather than all of them.)
  
  Each ScanFilter element consists of an attribute name to compare, along with the following:
  
  AttributeValueList - One or more values to evaluate against the supplied attribute. The number of values in the list depends on the operator specified in ComparisonOperator .
  
  For type Number, value comparisons are numeric.
  
  String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than B. For a list of code values, see http ://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.
  
  For Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.
  
  For information on specifying data types in JSON, see JSON Data Format in the Amazon DynamoDB Developer Guide.
  
  ComparisonOperator - A comparator for evaluating attributes. For example, equals, greater than, less than, etc.
  
  The following comparison operators are available:
  
  EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN

  getExpressionAttributeNames
  
  public Map<String,String> getExpressionAttributeNames()
  
  One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:
  
  To access an attribute whose name conflicts with a DynamoDB reserved word.
  
  To create a placeholder for repeating occurrences of an attribute name in an expression.
  
  To prevent special characters in an attribute name from being misinterpreted in an expression.
  
  Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:
  
  Percentile
  
  The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see Reserved Words in the Amazon DynamoDB Developer Guide). To work around this, you could specify the following for ExpressionAttributeNames:
  
  {"#P":"Percentile"}
  
  You could then use this substitution in an expression, as in this example:
  
  #P = :val
  
  Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.
  
  For more information on expression attribute names, see Accessing Item Attributes in the Amazon DynamoDB Developer Guide.
  
  Returns:
  One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:

  setConsistentRead
  
  public void setConsistentRead(Boolean consistentRead)
  
  A Boolean value that determines the read consistency model during the scan:
  
  If ConsistentRead is false, then Scan will use eventually consistent reads. The data returned from Scan might not contain the results of other recently completed write operations (PutItem, UpdateItem or DeleteItem). The Scan response might include some stale data.
  
  If ConsistentRead is true, then Scan will use strongly consistent reads. All of the write operations that completed before the Scan began are guaranteed to be contained in the Scan response.
  
  The default setting for ConsistentRead is false, meaning that eventually consistent reads will be used.
  
  Strongly consistent reads are not supported on global secondary indexes. If you scan a global secondary index with ConsistentRead set to true, you will receive a ValidationException.
