This contract is intended to be inherited and implemented by ERC721 token contracts requiring Rules Engine integration.

Abstract contract containing modifiers and functions for integrating ERC721 token operations with the Rules Engine. This contract provides policy checks for safeMint, transferFrom, and safeTransferFrom operations, both before and after execution.

Functions

checksPoliciesERC721SafeMintBefore

Modifier for checking policies before executing the safeMint function.

Calls the _checkPoliciesERC721SafeMint function to evaluate policies.

modifier checksPoliciesERC721SafeMintBefore(address to);

Parameters

Name	Type	Description
to	address	The receiving address.

checksPoliciesERC721SafeMintAfter

Modifier for checking policies after executing the safeMint function.

Calls the _checkPoliciesERC721SafeMint function to evaluate policies.

modifier checksPoliciesERC721SafeMintAfter(address to);

Parameters

Name	Type	Description
to	address	The receiving address.

checksPoliciesERC721SafeTransferFromBefore

Modifier for checking policies before executing the safeTransferFrom function.

Calls the _checkPoliciesERC721SafeTransferFrom function to evaluate policies.

modifier checksPoliciesERC721SafeTransferFromBefore(address from, address to, uint256 tokenId, bytes memory data);

Parameters

Name	Type	Description
from	address	The sending address.
to	address	The receiving address.
tokenId	uint256	The token identifier.
data	bytes	Generic data to pass along with the transfer.

checksPoliciesERC721SafeTransferFromAfter

Modifier for checking policies after executing the safeTransferFrom function.

Calls the _checkPoliciesERC721SafeTransferFrom function to evaluate policies.

modifier checksPoliciesERC721SafeTransferFromAfter(address from, address to, uint256 tokenId, bytes memory data);

Parameters

Name	Type	Description
from	address	The sending address.
to	address	The receiving address.
tokenId	uint256	The token identifier.
data	bytes	Generic data to pass along with the transfer.

checksPoliciesERC721TransferFromBefore

Modifier for checking policies before executing the transferFrom function.

Calls the _checkPoliciesERC721TransferFrom function to evaluate policies.

modifier checksPoliciesERC721TransferFromBefore(address from, address to, uint256 tokenId);

Parameters

Name	Type	Description
from	address	The sending address.
to	address	The receiving address.
tokenId	uint256	The token identifier.

checksPoliciesERC721TransferFromAfter

Modifier for checking policies after executing the transferFrom function.

Calls the _checkPoliciesERC721TransferFrom function to evaluate policies.

modifier checksPoliciesERC721TransferFromAfter(address from, address to, uint256 tokenId);

Parameters

Name	Type	Description
from	address	The sending address.
to	address	The receiving address.
tokenId	uint256	The token identifier.

_checkPoliciesERC721SafeMint

Calls the Rules Engine to evaluate policies for an ERC721 safeMint operation.

Encodes the parameters and invokes the _invokeRulesEngine function.

function _checkPoliciesERC721SafeMint(address _to) internal;

Parameters

Name	Type	Description
_to	address	The receiving address.

_checkPoliciesERC721SafeTransferFrom

Calls the Rules Engine to evaluate policies for an ERC721 safeTransferFrom operation.

Encodes the parameters and invokes the _invokeRulesEngine function.

function _checkPoliciesERC721SafeTransferFrom(address _from, address _to, uint256 _tokenId, bytes memory _data)
    internal;

Parameters

Name	Type	Description
_from	address	The sending address.
_to	address	The receiving address.
_tokenId	uint256	The token identifier.
_data	bytes	Generic data to pass along with the transfer.

_checkPoliciesERC721TransferFrom

Calls the Rules Engine to evaluate policies for an ERC721 transferFrom operation.

Encodes the parameters and invokes the _invokeRulesEngine function.

function _checkPoliciesERC721TransferFrom(address _from, address _to, uint256 _tokenId) internal;

Parameters

Name	Type	Description
_from	address	The sending address.
_to	address	The receiving address.
_tokenId	uint256	The token identifier.
