I Governor Compatibility Bravo Upgradeable

Interface extension that adds missing functions to the {Governor} core to provide GovernorBravo compatibility. Available since v4.3.

Methods

COUNTING_MODE

function COUNTING_MODE() external pure returns (string)

module:voting

A description of the possible support values for {castVote} and the way these votes are counted, meant to be consumed by UIs to show correct vote options and interpret the results. The string is a URL-encoded sequence of key-value pairs that each describe one aspect, for example support=bravo&quorum=for,abstain. There are 2 standard keys: support and quorum. - support=bravo refers to the vote options 0 = For, 1 = Against, 2 = Abstain, as in GovernorBravo. - quorum=bravo means that only For votes are counted towards quorum. - quorum=for,abstain means that both For and Abstain votes are counted towards quorum. NOTE: The string can be decoded by the standard https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams[URLSearchParams] JavaScript class.
