Constructor Detail

SAMv3Handler

public SAMv3Handler(SocketChannel s,
                    int verMajor,
                    int verMinor,
                    Properties i2cpProps,
                    SAMBridge parent)
             throws SAMException,
                    IOException

Create a new SAM version 3 handler. This constructor expects that the SAM HELLO message has been still answered (and stripped) from the socket input stream.

Parameters:

s - Socket attached to a SAM client

verMajor - SAM major version to manage (should be 3)

verMinor - SAM minor version to manage

i2cpProps - properties to configure the I2CP connection (host, port, etc)

Throws:

SAMException

IOException

SAMv3Handler

public SAMv3Handler(SocketChannel s,
                    int verMajor,

                    SAMBridge parent)
             throws SAMException,
                    IOException

Create a new SAM version 3 handler. This constructor expects that the SAM HELLO message has been still answered (and stripped) from the socket input stream.

Parameters:

s - Socket attached to a SAM client

verMajor - SAM major version to manage (should be 3)

verMinor - SAM minor version to manage

Throws:

SAMException

IOException
