DiamondLoupeFacet

This contract provides functions to inspect the facets of a diamond

Implements EIP-2535 Diamond standard's loupe functions

constructor

constructor() public

Sets the trusted forwarder to address(0)

Constructor that initializes the ERC2771Context with a trusted forwarder

facets

function facets() external view returns (struct IDiamondLoupe.Facet[] facets_)

Gets all facets and their selectors

Iterates through all facet addresses and retrieves their function selectors

Return Values

Name	Type	Description
facets_	struct IDiamondLoupe.Facet[]	An array of Facet structs containing facet addresses and their function selectors

facetFunctionSelectors

function facetFunctionSelectors(address _facet) external view returns (bytes4[] facetFunctionSelectors_)

Gets all the function selectors provided by a facet

Retrieves the function selectors for a given facet address

Parameters

Name	Type	Description
_facet	address	The facet address

Return Values

Name	Type	Description
facetFunctionSelectors_	bytes4[]	An array of function selectors supported by the facet

facetAddresses

function facetAddresses() external view returns (address[] facetAddresses_)

Get all the facet addresses used by a diamond

Retrieves the list of all facet addresses

Return Values

Name	Type	Description
facetAddresses_	address[]	An array of facet addresses

facetAddress

function facetAddress(bytes4 _functionSelector) external view returns (address facetAddress_)

Gets the facet that supports the given selector

If facet is not found, returns address(0)

Parameters

Name	Type	Description
_functionSelector	bytes4	The function selector

Return Values

Name	Type	Description
facetAddress_	address	The facet address that supports the given selector

_msgSender

function _msgSender() internal view virtual returns (address sender)

Internal function to get the sender address

_Overrides ERC2771Context's msgSender() for compatibility

Return Values

Name	Type	Description
sender	address	The address of the message sender

_msgData

function _msgData() internal view virtual returns (bytes)
