Public Methods
Creates and returns the final DnsOptions instance, based on the values in this
builder.
public
DnsOptions.Builder
enableStaleDns
(boolean enable)
Sets whether to use stale DNS results at all.
public
DnsOptions.Builder
preestablishConnectionsToStaleDnsResults
(boolean enable)
Sets whether Cronet should use stale cached DNS records to pre-establish connections.
If enabled, Cronet will optimistically pre-establish connections to servers that
matched the hostname at some point in the past and were cached but the cache entry
expired. Such connections won't be used further until a new DNS lookup confirms the
cached record was up to date.
To use cached DNS records straight away, use enableStaleDns(boolean) and DnsOptions.StaleDnsOptions configuration options.
This option may not be available for all networking protocols.
public
DnsOptions.Builder
setPersistHostCachePeriodMillis
(long persistHostCachePeriodMillis)
Sets the minimum period between subsequent writes to disk for DNS cache persistence.
Only relevant if persistHostCache(boolean) is set to true.
Parameters
| persistHostCachePeriodMillis |
|
Returns
- this builder for chaining.
