Method Detail
-
getItems
public List<Map<String,AttributeValue>> getItems()
An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.
- Returns:
- An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.
-
setItems
public void setItems(Collection<Map<String,AttributeValue>> items)
An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.
- Parameters:
items
- An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.
-
withItems
public QueryResult withItems(Map<String,AttributeValue>... items)
An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.
NOTE: This method appends the values to the existing list (if any). Use
setItems(java.util.Collection)
orwithItems(java.util.Collection)
if you want to override the existing values.- Parameters:
items
- An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.- Returns:
- Returns a reference to this object so that method calls can be chained together.
-
withItems
public QueryResult withItems(Collection<Map<String,AttributeValue>> items)
An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.
- Parameters:
items
- An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.- Returns:
- Returns a reference to this object so that method calls can be chained together.
-
setCount
public void setCount(Integer count)
The number of items in the response.
If you used a QueryFilter in the request, then Count is the number of items returned after the filter was applied, and ScannedCount is the number of matching items before the filter was applied.
If you did not use a filter in the request, then Count and ScannedCount are the same.
- Parameters:
count
- The number of items in the response.If you used a QueryFilter in the request, then Count is the number of items returned after the filter was applied, and ScannedCount is the number of matching items before the filter was applied.
If you did not use a filter in the request, then Count and ScannedCount are the same.
-
getCount
public Integer getCount()
The number of items in the response.
If you used a QueryFilter in the request, then Count is the number of items returned after the filter was applied, and ScannedCount is the number of matching items before the filter was applied.
If you did not use a filter in the request, then Count and ScannedCount are the same.
- Returns:
- The number of items in the response.
If you used a QueryFilter in the request, then Count is the number of items returned after the filter was applied, and ScannedCount is the number of matching items before the filter was applied.
If you did not use a filter in the request, then Count and ScannedCount are the same.
-
withCount
public QueryResult withCount(Integer count)
The number of items in the response.
If you used a QueryFilter in the request, then Count is the number of items returned after the filter was applied, and ScannedCount is the number of matching items before the filter was applied.
If you did not use a filter in the request, then Count and ScannedCount are the same.
- Parameters:
count
- The number of items in the response.If you used a QueryFilter in the request, then Count is the number of items returned after the filter was applied, and ScannedCount is the number of matching items before the filter was applied.
If you did not use a filter in the request, then Count and ScannedCount are the same.
- Returns:
- Returns a reference to this object so that method calls can be chained together.
-
setScannedCount
public void setScannedCount(Integer scannedCount)
The number of items evaluated, before any QueryFilter is applied. A high ScannedCount value with few, or no, Count results indicates an inefficient Query operation. For more information, see Count and ScannedCount in the Amazon DynamoDB Developer Guide.
If you did not use a filter in the request, then ScannedCount is the same as Count.
- Parameters:
scannedCount
- The number of items evaluated, before any QueryFilter is applied. A high ScannedCount value with few, or no, Count results indicates an inefficient Query operation. For more information, see Count and ScannedCount in the Amazon DynamoDB Developer Guide.If you did not use a filter in the request, then ScannedCount is the same as Count.
-
getScannedCount
public Integer getScannedCount()
The number of items evaluated, before any QueryFilter is applied. A high ScannedCount value with few, or no, Count results indicates an inefficient Query operation. For more information, see Count and ScannedCount in the Amazon DynamoDB Developer Guide.
If you did not use a filter in the request, then ScannedCount is the same as Count.
- Returns:
- The number of items evaluated, before any QueryFilter is
applied. A high ScannedCount value with few, or no,
Count results indicates an inefficient Query
operation. For more information, see Count and ScannedCount in the Amazon DynamoDB Developer
Guide.
If you did not use a filter in the request, then ScannedCount is the same as Count.
-
withScannedCount
public QueryResult withScannedCount(Integer scannedCount)
The number of items evaluated, before any QueryFilter is applied. A high ScannedCount value with few, or no, Count results indicates an inefficient Query operation. For more information, see Count and ScannedCount in the Amazon DynamoDB Developer Guide.
If you did not use a filter in the request, then ScannedCount is the same as Count.
- Parameters:
scannedCount
- The number of items evaluated, before any QueryFilter is applied. A high ScannedCount value with few, or no, Count results indicates an inefficient Query operation.

-
getLastEvaluatedKey
public Map<String,AttributeValue> getLastEvaluatedKey()
The primary key of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request.
