EstablishState (Javadocs [I2P+ 2.13.0+]

All Known Implementing Classes:
EstablishBase, InboundEstablishState, OutboundNTCP2State
```
interface EstablishState
```
Interface for handling NTCP connection establishment state machine. Manages the handshake process for both NTCP 1 and NTCP 2 protocols, including parsing handshake data, preparing outbound connections, and tracking establishment completion status.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`void`	`close(String reason, Exception e)` Release resources on timeout.
`String`	`getFailReason()` Failure reason, or null if not failed.
`int`	`getVersion()` NTCP version.
`boolean`	`isComplete()` If synchronized on this, fails with deadlocks from all over via CSFI.isEstablished().
`boolean`	`isCorrupt()` Whether the handshake failed.
`void`	`prepareOutbound()` Does nothing.
`void`	`receive(ByteBuffer src)` Parse the contents of the buffer as part of the handshake.

- Method Detail
  - close
```
void close(String reason,
           Exception e)
```
    Release resources on timeout.
    Parameters:
    reason - the reason
    e - may be null
  - getFailReason
```
String getFailReason()
```
    Failure reason, or null if not failed.
    Returns:
    the failure reason, or null if not failed
  - getVersion
```
int getVersion()
```
    NTCP version.
    Returns:
    1, 2, or 0 if unknown
  - isComplete
```
boolean isComplete()
```
    If synchronized on this, fails with deadlocks from all over via CSFI.isEstablished(). Also CSFI.getFramedAveragePeerClockSkew().
    Returns:
    is the handshake complete and valid?
  - isCorrupt
```
boolean isCorrupt()
```
    Whether the handshake failed.
    Returns:
    whether the handshake failed
  - prepareOutbound
```
void prepareOutbound()
```
    Does nothing. Outbound (Alice) must override. We are establishing an outbound connection, so prepare ourselves by queueing up the write of the first part of the handshake
    Throws:
    IllegalStateException - on invalid state
  - receive
```
void receive(ByteBuffer src)
```
    Parse the contents of the buffer as part of the handshake. All data must be copied out of the buffer as Reader.processRead() will return it to the pool. If there are additional data in the buffer after the handshake is complete, the EstablishState is responsible for passing it to NTCPConnection.
    Parameters:
    src - the buffer to parse
    Throws:
    IllegalStateException - on invalid state
