Method Details

getSyncThreshold

public long getSyncThreshold()

This should only be used in case you need to get the EnsResolver.getSyncThreshold() parameter, which dictates the threshold in milliseconds since the last processed block timestamp should be to considered in sync the blockchain.

It is currently experimental and only used in ENS name resolution, but will probably be made available for read calls in the future.

Returns:

sync threshold value in milliseconds

setSyncThreshold

public void setSyncThreshold(long syncThreshold)

This should only be used in case you need to modify the EnsResolver.getSyncThreshold() parameter, which dictates the threshold in milliseconds since the last processed block timestamp should be to considered in sync the blockchain.

It is currently experimental and only used in ENS name resolution, but will probably be made available for read calls in the future.

Parameters:

syncThreshold - the sync threshold in milliseconds

requestCurrentGasPrice

public BigInteger requestCurrentGasPrice()
                                  throws IOException

Return the current gas price from the ethereum node.

Note: this method was previously called getGasPrice but was renamed to distinguish it when a bean accessor method on Contract was added with that name. If you have a Contract subclass that is calling this method (unlikely since those classes are usually generated and until very recently those generated subclasses were marked final), then you will need to change your code to call this method instead, if you want the dynamic behavior.

Returns:

the current gas price, determined dynamically at invocation

Throws:

IOException - if there's a problem communicating with the ethereum node
