DeleteItemRequest (AWS SDK for Android

java.lang.Object
- com.amazonaws.AmazonWebServiceRequest
- - com.amazonaws.services.dynamodbv2.model.DeleteItemRequest

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable
```
public class DeleteItemRequest
extends AmazonWebServiceRequest
implements java.io.Serializable
```
Deletes a single item in a table by primary key. You can perform a conditional delete operation that deletes the item if it exists, or if it has an expected attribute value.

In addition to deleting an item, you can also return the item's attribute values in the same operation, using the ReturnValues parameter.

Unless you specify conditions, the DeleteItem is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.

Conditional deletes are useful for deleting items only if specific conditions are met. If those conditions are met, DynamoDB performs the delete. Otherwise, the item is not deleted.

    returnValues -
    Use ReturnValues if you want to get the item attributes as they appeared before they were deleted. For DeleteItem, the valid values are:
    
    NONE - If ReturnValues is not specified, or if its value is NONE, then nothing is returned. (This setting is the default for ReturnValues.)
    
    ALL_OLD - The content of the old item is returned.

  - getExpressionAttributeNames
```
public java.util.Map<java.lang.String,java.lang.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.

    You could then use these values in an expression, such as this:
    
    ProductStatus IN (:avail, :back, :disc)
    
    For more information on expression attribute values, see Specifying Conditions in the Amazon DynamoDB Developer Guide.
    
    Parameters:
    
    expressionAttributeValues -
    One or more values that can be substituted in an expression.
    
    Use the : (colon) character in an expression to dereference an attribute value. For example, suppose that you wanted to check whether the value of the ProductStatus attribute was one of the following:
    
    Available | Backordered | Discontinued
    
    You would first need to specify ExpressionAttributeValues as follows:
    
    { ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"} }
    
    You could then use these values in an expression, such as this:
    
    ProductStatus IN (:avail, :back, :disc)

    The method adds a new key-value pair into ExpressionAttributeValues parameter, and returns a reference to this object so that method calls can be chained together.
    
    Parameters:
    
    key - The key of the entry to be added into ExpressionAttributeValues.
    
    value - The corresponding value of the entry to be added into ExpressionAttributeValues.
    
    Returns:
    
    A reference to this updated object so that method calls can be chained together.
  - clearExpressionAttributeValuesEntries
```
public DeleteItemRequest clearExpressionAttributeValuesEntries()
```
    Removes all the entries added into ExpressionAttributeValues.
    Returns a reference to this object so that method calls can be chained together.
