Definition

function acceptsToken(address _token, uint256 _projectId) external view override returns (bool) { ... }

• Arguments:
  • _token is the token to check if this terminal accepts or not.
  • _projectId is the project ID to check for token acceptance.
• The view function can be accessed externally by anyone.
• The view function does not alter state on the blockchain.
• The resulting function overrides a function definition from the IJBPaymentTerminal interface.
• The function returns the flag.

Body

1. Get a reference to the v1 project that has been attached to the specified v2 project.

   // Get a reference to the V1 project for the provided project ID.
   uint256 _v1ProjectId = v1ProjectIdOf[_projectId];

   Internal references:

   • v1ProjectIdOf

2. This terminal should not accept a token if it's been explicitly set by the project, and the exchanging has not yet been finalized.

   // Accept the token if it has been set and the exchange hasn't yet finalized.
   return address(ticketBooth.ticketsOf(_v1ProjectId)) == _token && !finalized[_v1ProjectId];

   Internal references:

   • finalized
   • ticketBooth

   External references:
