public java.util.Map<String, AttributeValue> getItem() {
        return item;
    }
<p>
A map of attribute name/value pairs, one for each attribute. Only the primary key attributes are required; you
can optionally provide other attribute name-value pairs for the item.
</p>
<p>
You must provide all of the attributes for the primary key. For example, with a simple primary key, you only need
to provide a value for the partition key. For a composite primary key, you must provide both values for both the
partition key and the sort key.
</p>
<p>
If you specify any attributes that are part of an index key, then the data types for those attributes must match
those of the schema in the table's attribute definition.
</p>
<p>
Empty String and Binary attribute values are allowed. Attribute values of type String and Binary must have a
length greater than zero if the attribute is used as a key attribute for a table or index.
</p>

<p>
Each element in the <code>Item</code> map is an <code>AttributeValue</code> object.
