Parameters:
Returns:
blockHash - The 32 byte hash of a block that meets your filter requirements
transactionHash - The 32 byte hash of a transaction that meets your filter requirements
address - An address from which this log originated
topics - An array of zero to four 32 Bytes DATA of indexed log arguments. In Solidity, the first topic is the hash of the signature of the event (e.g. Deposit(address, bytes32, uint256)), except you declare the event with the anonymous specifier
data - It contains one or more 32 Bytes non-indexed arguments of the log
blockNumber - The block number where this log was in. null when its a pending log
transactionHash - The hash of the transactions this log was created from. null when its a pending log
transactionIndex - The integer of the transaction's index position that the log was created from. null when it's a pending log
blockHash - The hash of the block where this log was in. null when its a pending log
logIndex - The integer of the log index position in the block. null when it's a pending log
removed - It is true when the log was removed due to a chain reorganization, and false if it's a valid log
