ERC721EnumerableV2

This function is used to initialize the ERC721EnumerableExtended contract. It calls the __ERC721Enumerable_init() function which is used to initialize the ERC721Enumerable contract. This ensures that the ERC721EnumerableExtended contract has all the necessary functions and variables from the ERC721Enumerable contract. (autogenerated documentation)

This function is used to initialize the ERC721EnumerableExtended contract. It is an internal function that is only called when the contract is first deployed. It does not have any code in it, so it does not perform any specific tasks. (autogenerated documentation)

This function allows for the transfer of multiple ERC-721 tokens from one address to another. It takes in three parameters: the address of the sender, the address of the recipient, and an array of token IDs. It then iterates through the array of token IDs and calls the transferFrom() function for each token ID, transferring the tokens from the sender to the recipient. (autogenerated documentation)

This function returns an array of uint256 values that represent the tokens owned by a given address (owner). It does this by first getting the total number of tokens owned by the owner using the balanceOf() function from the ERC721Upgradeable contract. It then creates an array of uint256 values with the same length as the total number of tokens owned. Finally, it iterates through the array and populates it with the token IDs of the tokens owned by the owner, using the tokenOfOwnerByIndex() function. (autogenerated documentation)

This function is used to get all the token IDs that have been created in the contract. It first creates a count variable to keep track of the number of token IDs that have been created. It then creates an array of uint256 type with the size of the count variable. It then iterates through all the token IDs from 1 to 10,000 and checks if the token ID exists in the contract. If it does, it adds the token ID to the array and increments the index. Finally, it returns the array of token IDs. (autogenerated documentation)

This function is used to check if a contract supports a given interface. It takes a bytes4 interfaceId as an argument and returns a boolean value indicating whether the contract supports the interface or not. The function works by calling the super.supportsInterface() function, which checks if the interfaceId matches any of the interfaces supported by the contract. If it does, the function returns true, otherwise it returns false. (autogenerated documentation)

This function is an internal virtual override of the _beforeTokenTransfer function from the ERC721Upgradeable and ERC721EnumerableUpgradeable contracts. It is used to perform certain operations before a token transfer is executed. Specifically, it checks that the token transfer is valid and that the sender has the necessary balance of tokens to complete the transfer. It also updates the token balances of the sender and receiver accordingly. (autogenerated documentation)
