+# 4 - ASN/1 TLV
+
+## What are TLVs ?
+
+The acronym **TLV** stands for **T**ag, **L**ength and **V**alue. It's a way to encode a
piece of information with a type, a length followed by the information itself. Three points
must be known:
+
+* The **Value** part may contents other **TLV**s. One can see **TLV**s as C structures, that
can contain sub-structures.
+* The **Value** may not exist, and in this case the **Length** will be 0.
+* The **Length** part may not give the **Value** length: it is called an _indefinite Length_.
In this - not so frequent - case, the **Value** must end with a specific terminator.
+
+### A quick sample
+
+Let's begin with a simple example, without too many explanations. This is the **PDU** (**P**acket
**D**ata **U**nit) of a LDAP _BindRequest_:
+
+![TLV](../images/TLVs.png)
+
+We can see in this picture that you have what is called a first level **TLV**. It encapsulates
other **TLV**s. It's basically a stream of bytes.
+
+
+### Type
+
+Each **Type** contains information about the **Value** part of the **TLV**. It tells if the
**Value** is a primitive or a constructed one, which type of primitive is the value, gives
some contextual information. A **Type** can be coded on more than one byte. The first 3 bits
give some contextual information about the **Type**, and the 5 following bits are either a
label or the beginning of a multi-bytes label.
+
+* Labels are numbers in [0..30], and they represent a specific **ASN/1** element in the protocol
description, like _CompareRequest ::= [APPLICATION 14] _ (here, the label is 14). 
+* If the label is 31, then more than one byte is used to encode the **Type**. In this case,
we use the following bytes to compute the label, where each byte which high bit is one will
be followed by another byte. 
+
+We limit the label to 2,097,151 as we encode the **Type** in one Java int : 
+
+    :::
+    b1 xxx[1-1111], b2 1[111-1111], b3 1[111-1111], b4 0[111-1111]
+    ->
+    [111-1111][111-1111][111-1111] 
+    ->
+    0001-1111 1111-1111 1111-1111
+    ->
+    0x1FFFFF
+    -> 
+    2,097,151
+
+In **LDAP** or **Kerberos**, no label is higher than 30, so we always use 1 byte **Type**s.
+
+Other interesting information that we need to grab from a *Type* are stored in the two first
bits (bit 7 and 6), and in the third bit (bit 5). The first two bits describe the class, the
third tells if the **TLV** is a **primitive** (b5 = 0) or a **constructed** **TLV** (b5 =
1).
+
+
+### Length
+
+**Length** gives the number of bytes of the **Value**, and nothing else. So the total length
of a **TLV** will be:
+
+    :::
+    TLV length = Tag length + Length length + Value length, 
+
+where the **Value** length is stored in the **Length** element.
+
+The **Length** may be 0, which means that there is no value following.
+
+How is **Length** encoded? A **Value** may be from 0 to N bytes long, with N < (256 ^
126) - 1. This limit is purely hypothetic, of course. If we have to deal with huge objects
like pictures or movies, their length will not exceed a few MBytes or a few GBytes
+
+Typically, we will find five kind of **Length**s :
+
+* zero length values;
+* values with a length less than 128 bytes
+* values with a length between 128 and 256 ^ 4 bytes long (an int will be able to hold 4
bytes);
+* values above 256 ^ 4 bytes long
+* values which length is not defined by the **Length** element.
+
+The last type of Length could occurs if the sender does not know the length of the value
while it is sending it. **LDAP** protocol does not allow those kind of values, which are dangerous
because you need to read the full **Value** to know its length.
+
+The fourth type could also be ignored (4 GBytes is quite a huge size for an LDAP element
...), so we can decide that we won't accept those **Values**. It seems reasonable.
+
+As the **Length** can be stored in more than one byte, we have to take care of fragmented
**PDU** : we may receive only the first bytes, and have to wait for the rest to be received.
The idea is to freeze and start again when we receive some more data.
+
+In any case, if the first byte is > 0x7F, that means it's a multi-bytes length, and we
have to process the following bytesto get the real length. In this case, the first byte contains
teh number of expected following bytes. Typically :
+
+    :::
+    0x74 -> 116
+    0x82 0x02 0x84 : 2 bytes, length = 2 * 16 + 132 -> 164
+    0x81 0x84 : 1 byte, length = 132
+
+
+### Value
+
+**Value** carries the 'meat' of a **TLV**. Depending on the **Type**, it's either a primitive
value, or a constructed one (which means it contains a **TLV** or a set of **TLV**s). Remember
that bit 5 of the **Type** tells if the **Value is _primitive_ ( b5 == 0) or _constructed
(b5 == 1).
+
+* If we have a _primitive_ **Value**, we have to read **Length** byte and we are done
+** If we have a _constructed_ **Value**, we have to process it as one or more **TLV**.
+
+
+## TLV processing
+
+In the **API**, the **TLV** processing is done in the _Asn1Decoder_ class, and more specifically
by the _decode( ByteBuffer stream, Asn1Container container )_ method, which takes a ByteBuffer
as input, and feed a container as a result. 
+
+The important thing to understand is that this method can be called repetively, until a message
is fully decoded, as soon as we feed it with some new _ByteBuffer_. The _Container_ instance
will contain the result, as soon as its state has switched to **PDU_DECODED**.
+
+While processing a **TLV**, when we are done with the **Value** part, the decoder will check
if any action is to be executed. The action is associated to the grammar in use, which is
stored in the container. Here is the part that call the action, in the _Asn1Decoder.treatTLVDoneState()_
method :
+
+    :::java
+    private boolean treatTLVDoneState( ByteBuffer stream, Asn1Container container ) throws
DecoderException
+    {
+        // First, we have to execute the associated action
+        container.getGrammar().executeAction( container );
+        ...
+
+So the _Container_ must contain the grammar, and the current state. We may not have any action
to execute, either because none is associated with the current transition or because we are
at the end of the message.
