Interface QuicConnectionIdGenerator

public interface QuicConnectionIdGenerator

Creates new connection id instances.

Method Summary

Modifier and Type	Method and Description
boolean	isIdempotent() Returns true if the implementation is idempotent, which means we will get the same id with the same input ByteBuffer.
int	maxConnectionIdLength() Returns the maximum length of a connection id.
java.nio.ByteBuffer	newId(java.nio.ByteBuffer input, int length) Creates a new connection id with the given length.
java.nio.ByteBuffer	newId(int length) Creates a new connection id with the given length.
static QuicConnectionIdGenerator	randomGenerator() Return a QuicConnectionIdGenerator which randomly generates new connection ids.
static QuicConnectionIdGenerator	signGenerator() Return a QuicConnectionIdGenerator which generates new connection ids by signing the given input.

Method Detail

newId

java.nio.ByteBuffer newId(int length)

Creates a new connection id with the given length. This method may not be supported by a sign id generator implementation as a sign id generator should always have an input to sign with, otherwise this method may generate the same id which may cause some unpredictable issues when we use it.

Parameters:

length - the length of the id.

Returns:

the id.

newId

java.nio.ByteBuffer newId(java.nio.ByteBuffer input,
                          int length)

Creates a new connection id with the given length. The given input may be used to sign or seed the id, or may be ignored (depending on the implementation).

Parameters:

input - the input which may be used to generate the id.

length - the length of the id.

Returns:

the id.

maxConnectionIdLength

int maxConnectionIdLength()

Returns the maximum length of a connection id.

Returns:

the maximum length of a connection id that is supported.

isIdempotent

boolean isIdempotent()

Returns true if the implementation is idempotent, which means we will get the same id with the same input ByteBuffer. Otherwise, returns false.

Returns:

whether the implementation is idempotent.

randomGenerator

static QuicConnectionIdGenerator randomGenerator()

Return a QuicConnectionIdGenerator which randomly generates new connection ids.

Returns:

a QuicConnectionIdGenerator which randomly generated ids.

signGenerator

static QuicConnectionIdGenerator signGenerator()

Return a QuicConnectionIdGenerator which generates new connection ids by signing the given input.

Returns:

a QuicConnectionIdGenerator which generates ids by signing the given input.
