BaseRainterpreterExternNPE2

Inherits: IInterpreterExternV3, ERC165

Base implementation of IInterpreterExternV3. Inherit from this contract, and override functionPointers to provide a list of function pointers.

Functions

extern

Handles a single dispatch.

function extern(ExternDispatch dispatch, uint256[] memory inputs)
    external
    view
    virtual
    override
    returns (uint256[] memory outputs);

Parameters

Name	Type	Description
`dispatch`	`ExternDispatch`	Encoded information about the extern to dispatch. Analogous to the opcode/operand in the interpreter.
`inputs`	`uint256[]`	The array of inputs for the dispatched logic.

Returns

Name	Type	Description
`outputs`	`uint256[]`	The result of the dispatched logic.

externIntegrity

Checks the integrity of some extern call.

function externIntegrity(ExternDispatch dispatch, uint256 expectedInputs, uint256 expectedOutputs)
    external
    pure
    virtual
    override
    returns (uint256 actualInputs, uint256 actualOutputs);

Parameters

Name	Type	Description
`dispatch`	`ExternDispatch`	Encoded information about the extern to dispatch. Analogous to the opcode/operand in the interpreter.
`expectedInputs`	`uint256`	The number of inputs expected for the dispatched logic.
`expectedOutputs`	`uint256`	The number of outputs expected for the dispatched logic.

Returns

Name	Type	Description
`actualInputs`	`uint256`	The actual number of inputs for the dispatched logic.
`actualOutputs`	`uint256`	The actual number of outputs for the dispatched logic.

supportsInterface

See {IERC165-supportsInterface}.

function supportsInterface(bytes4 interfaceId) public view virtual override returns (bool);

opcodeFunctionPointers

Overrideable function to provide the list of function pointers for word dispatches.

function opcodeFunctionPointers() internal view virtual returns (bytes memory);

integrityFunctionPointers

Overrideable function to provide the list of function pointers for integrity checks.

function integrityFunctionPointers() internal pure virtual returns (bytes memory);
