Inherits: JBOwnableOverrides

A function restricted by JBOwnable can only be called by a Juicebox project's owner, a specified owner address (if set), or addresses with permission from the owner.

*A function with the onlyOwner modifier from JBOwnable can only be called by addresses with owner access based on a JBOwner struct:

1. If JBOwner.projectId isn't zero, the address holding the JBProjects NFT with the JBOwner.projectId ID is the owner.
2. If JBOwner.projectId is set to 0, the JBOwner.owner address is the owner.
3. The owner can give other addresses access with JBPermissions.setPermissionsFor(...), using the JBOwner.permissionId permission.*

To use onlyOwner, inherit this contract and apply the modifier to a function.

Functions

constructor

To make a Juicebox project's owner this contract's owner, pass that project's ID as the initialProjectIdOwner.

To make a specific address the owner, pass that address as the initialOwner and 0 as the initialProjectIdOwner.

The owner can give other addresses owner access through the permissions contract.

constructor(
    IJBPermissions permissions,
    IJBProjects projects,
    address initialOwner,
    uint88 initialProjectIdOwner
)
    JBOwnableOverrides(permissions, projects, initialOwner, initialProjectIdOwner);

Parameters

Name	Type	Description
permissions	IJBPermissions	A contract storing permissions.
projects	IJBProjects	Mints ERC-721s that represent project ownership and transfers.
initialOwner	address	An address with owner access (until ownership is transferred).
initialProjectIdOwner	uint88	The ID of the Juicebox project whose owner has owner access (until ownership is transferred).

onlyOwner

Reverts if called by an address without owner access.

modifier onlyOwner() virtual;

_emitTransferEvent

Either newOwner or newProjectId is non-zero or both are zero. But they can never both be non-zero.

This function exists because some contracts will try to deploy contracts for a project before

function _emitTransferEvent(address previousOwner, address newOwner, uint88 newProjectId) internal virtual override;
