public I2PDatagramMaker(I2PSession session)
```
    Construct a new I2PDatagramMaker that will be able to create I2P repliable datagrams going to be sent through the specified I2PSession. Does NOT support LS2 offline keys!
    Parameters:
    session - I2PSession used to send I2PDatagrams through
    Throws:
    IllegalArgumentException - if session has offline keys

```
public byte[] makeI2PDatagram(byte[] payload)
```
    Make a repliable I2P datagram containing the specified payload. Format is:
    1. Destination (387+ bytes)
    2. Signature (40+ bytes, type and length as implied by signing key type in the Destination)
    3. Payload
    Maximum datagram size is ~64KB, so maximum payload size is a little less. Practical maximum is a few KB less due to Destination and Garlic overhead. 10 KB or less is recommended for best results. For DSA_SHA1 Destinations, the signature is of the SHA-256 Hash of the payload. As of 0.9.14, for non-DSA_SHA1 Destinations, the signature is of the payload itself.
    Parameters:
    payload - non-null Bytes to be contained in the I2P datagram.
    Returns:
    null on error
    Throws:
    IllegalArgumentException - if payload is too big
    IllegalStateException - if Destination signature type unsupported
  - setI2PDatagramMaker
```
public void setI2PDatagramMaker(I2PSession session)
```
    Does NOT support LS2 offline keys!
    Parameters:
    session - I2PSession used to send I2PDatagrams through
    Throws:
    IllegalArgumentException - if session has offline keys
