Parameters

QUANTITY - the filter id.

params: ["0x0700000000000000bf0b1f4b27e765fb"];

Returns

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 declare the event with the anonymous specifier.
