+Data Class
+==========
+
+:[C++]:
+    Namespace: ``ndn``
+
+:[Python]:
+    Module: ``pyndn``
+
+Data Constructor
+----------------
+
+Create a new Data with the optional values.
+
+:[C++]:
+
+.. code-block:: c++
+
+    Data(
+    
+        [const Name& name]
+    
+    );
+
+:[JavaScript]:
+
+.. code-block:: javascript
+
+    var Data = function Data(
+    
+        [name         // Name]
+    
+    )
+
+:[Python]:
+
+.. code-block:: python
+
+    def __init__(self
+    
+        [, name       // Name]
+    
+    )
+
+:Parameters:
+
+    - ``name``
+	(optional) The name for the data packet.
+
+Data.getContent Method
+----------------------
+
+Get content of the Data packet.
+
+:[C++]:
+
+.. code-block:: c++
+
+    const Blob& getContent() const;
+
+:[JavaScript]:
+
+.. code-block:: javascript
+
+    // Returns Blob
+    Data.prototype.getContent = function()
+    
+:Returns:
+
+    A pointer to the content byte array.
+
+Data.setContent Method
+----------------------
+
+Set content to point to an existing byte array.
+
+:[C++]:
+
+.. code-block:: c++
+
+    void setContent(
+    
+        const Blob& content
+    
+    );
+
+:Parameters:
+
+    - ``content``
+	The pointer to the byte array.
+
+Data.wireDecode Method
+----------------------
+
+Decode the input using a particular wire format and update this Data. If wireFormat is the default wire format, also set the defaultWireEncoding field to the input.
+
+:[C++]:
+
+.. code-block:: c++
+
+    void wireDecode(
+    
+        const std::vector<uint8_t>& input
+	[, WireFormat& wireFormat]
+    
+    );
+
+:[JavaScript]:
+
+.. code-block:: javascript
+
+    ContentObject.prototype.decode = function(
+    
+        input // Uint8Array
+        [, wireFormat // WireFormat]
+    
+    )
+
+:Parameters:
+
+    - ``input``
+	The input byte array to be decoded.
+
+    - ``wireFormat``
+	(optional) A WireFormat object used to decode the input. If omitted, use WireFormat getDefaultWireFormat().
+
+Data.wireEncode Method
+----------------------
+
+Encode this Data for a particular wire format. If wireFormat is the default wire format, also set the defaultWireEncoding field to the encoded result.
+
+:[C++]:
+
+.. code-block:: c++
+
+    SignedBlob wireEncode(
+    
+        [WireFormat& wireFormat]
+    
+    ) const;
+
+:[JavaScript]:
+
+.. code-block:: javascript
+
+    // Returns Uint8Array
+    ContentObject.prototype.encode = function(
+    
+        [wireFormat // WireFormat]
+    
+    )
+
+:Parameters:
+
+    - wireFormat
+	(optional) A WireFormat object used to encode the input. If omitted, use WireFormat getDefaultWireFormat ().
+
+:Returns:
+
+    The encoded byte array as a SignedBlob.
