Polling method for a filter, which returns an array of logs which occurred since last poll.
This method will use 20 Compute Units.
QUANTITY - the filter id.
Array - Array of log objects, or an empty array if nothing has changed since last poll.
For filters created with eth_newBlockFilter the return are block hashes (DATA, 32 Bytes), e.g. ["0x3454645634534..."].
For filters created with eth_newPendingTransactionFilter the return are transaction hashes (DATA, 32 Bytes), e.g. ["0x6345343454645..."].
For filters created with eth_newFilter logs are objects with following params:
removed: TAG - true when the log was removed, due to a chain reorganization. false if its a valid log.
logIndex: QUANTITY - integer of the log index position in the block. null when its pending log.
transactionIndex: QUANTITY - integer of the transactions index position log was created from. null when its pending log.
transactionHash: DATA, 32 Bytes - hash of the transactions this log was created from. null when its pending log.
blockHash: DATA, 32 Bytes - hash of the block where this log was in. null when its pending. null when its pending log.
blockNumber: QUANTITY - the block number where this log was in. null when its pending. null when its pending log.
address: DATA, 20 Bytes - address from which this log originated.
data: DATA - contains one or more 32 Bytes non-indexed arguments of the log.
topics: Array of DATA - Array of 0 to 4 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 declared the event with the anonymous specifier.)
