Polling method for a filter, which returns an array of logs which occurred since last poll.
Parameters
- QUANTITY - The filter id.
params: ["0xfe704947a3cd3ca12541458a4321c869"];
Returns
Array - Array of log objects, or an empty array if nothing has changed since last poll.
NOTE: eth_getFilterChanges only returns logs since the filter was created, regardless of the block passed in to create the filter. To get logs ranging from a specific block you should use eth_getLogs .
- 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.
