constructor(address _resource, uint256 _threshold, address _tokenJar, address _recipient)
  ResourceManager(_resource, _threshold, msg.sender, _recipient);

Parameters

Name	Type	Description
`_resource`	`address`	The address of the resource token that must be transferred
`_threshold`	`uint256`
`_tokenJar`	`address`	The address of the TokenJar contract holding the assets
`_recipient`	`address`	The address that will receive the resource tokens

release

Releases assets to a specified recipient if the resource threshold is met

function release(uint256 _nonce, Currency[] calldata assets, address recipient) external virtual;

Parameters

Name	Type	Description
`_nonce`	`uint256`	The nonce for the release, must equal to the contract nonce otherwise revert
`assets`	`Currency[]`	The list of assets (addresses) to release, which may have length limits Native tokens (Ether) are represented as the zero address
`recipient`	`address`	The address to receive the released assets, paid out by Token Jar
