ForkCriteria	Type that represents the condition required for a fork to occur.

Module Details

ForkCriteria

Type that represents the condition required for a fork to occur.

class ForkCriteria

Bases: abc.ABC

BLOCK_NUMBER :Final[int] = 0

TIMESTAMP :Final[int] = 1

UNSCHEDULED :Final[int] = 2

_internal :Tuple[int, int]

__eq__(other: object) → bool

Equality for fork criteria.

__lt__(other: object) → bool

Ordering for fork criteria. Block number forks are before timestamp forks and scheduled forks are before unscheduled forks.

__hash__() → int

ForkCriteria is hashable, so it can be stored in dictionaries.

abstract check(block_number: int, timestamp: int) → bool

Check whether fork criteria have been met.

abstract __repr__() → str

String representation of this object.

ByBlockNumber

Forks that occur when a specific block number has been reached.

class ByBlockNumber(block_number: int)

Bases: ForkCriteria

block_number :int

check(block_number: int, timestamp: int) → bool

Check whether the block number has been reached.

__repr__() → str

String representation of this object.

ByTimestamp

Forks that occur when a specific timestamp has been reached.

class ByTimestamp(timestamp: int)

Bases: ForkCriteria

timestamp :int

check(block_number: int, timestamp: int) → bool

Check whether the timestamp has been reached.

__repr__() → str

String representation of this object.

Unscheduled

Forks that have not been scheduled.

class Unscheduled

Bases: ForkCriteria

check(block_number: int, timestamp: int) → bool

Unscheduled forks never occur.

__repr__() → str

String representation of this object.
