Example 26 with AionBlock

use of org.aion.zero.impl.types.AionBlock in project aion by aionnetwork.

the class ApiWeb3Aion method eth_newFilter.

     * filters

/* Web3 Filters Support
     *
     * NOTE: newFilter behaviour is ill-defined in the JSON-rpc spec for the following scenarios:
     * (an explanation of how we resolved these ambiguities follows immediately after)
     *
     * newFilter is used to subscribe for filter on transaction logs for transactions with provided address and topics
     *
     * role of fromBlock, toBlock fields within context of newFilter, newBlockFilter, newPendingTransactionFilter
     * (they seem only more pertinent for getLogs)
     * how we resolve it: populate historical data (best-effort) in the filter response before "installing the filter"
     * onus on the user to flush the filter of the historical data, before depending on it for up-to-date values.
     * apart from loading historical data, fromBlock & toBlock are ignored when loading events on filter queue
