supportsInterface(bytes4) :
This function checks whether a given interfaceId is supported by the contract. It does this by comparing the given interfaceId to the interfaceId of the IERC1155CreatorCore interface, and if they match, it returns true. If they don't match, it calls the super.supportsInterface() function to check if the interfaceId is supported by the parent contract (in this case, IERC165). If it is, it returns true, otherwise it returns false. (autogenerated documentation)
_setApproveTransferExtension(address,bool) :
This function sets the approval of a transfer extension for a given address. It first checks if the extension supports the IERC1155CreatorExtensionApproveTransfer interface, and if so, it sets the approval status of the extension to the given boolean value. It then emits an ExtensionApproveTransferUpdated event with the extension address and the new approval status. (autogenerated documentation)
_setMintPermissions(address,address) :
This function sets the minting permissions for a given extension address. It requires that the extension address is valid and that the permissions address is either 0 or an address that supports the IERC1155CreatorMintPermissions interface. If the permissions are updated, an event is emitted. (autogenerated documentation)
_checkMintPermissions(uint256[],uint256[]) :
This function is used to check the minting permissions of a given address. It takes in an array of addresses, an array of tokenIds, and an array of amounts as parameters. It then checks if the sender of the message has an extension permission set. If so, it calls the approveMint function from the IERC1155CreatorMintPermissions contract, passing in the sender, the array of addresses, the array of tokenIds, and the array of amounts as parameters. This function is used to ensure that the sender has the necessary permissions to mint the specified tokens. (autogenerated documentation)
_postBurn(address,uint256[],uint256[]) :
This function is used to burn a set of ERC-1155 tokens. It takes in an owner address, an array of token IDs, and an array of amounts as parameters. It first checks that the tokenIds array is not empty, and that all the tokens in the array have the same originator. It then checks if the originator supports the IERC1155CreatorExtensionBurnable interface, and if so, calls the onBurn function on the originator with the owner, tokenIds, and amounts as parameters. (autogenerated documentation)
_approveTransfer(address,address,uint256[],uint256[]) :
This function is used to approve a transfer of tokens from one address to another. It takes in the addresses of the sender and receiver, an array of token IDs, and an array of amounts. It first checks that the token IDs provided are all from the same originator, and then checks if the originator has an extension that requires approval for transfers. If so, it calls the extension's approveTransfer function to approve the transfer. (autogenerated documentation)
