方法详细资料

loadConf

TableViewBuilder<T> loadConf(Map<String,Object> config)

Load the configuration from provided config map.

Example:

  Map<String, Object> config = new HashMap<>();
  config.put("topicName", "test-topic");
  config.put("autoUpdatePartitionsSeconds", "300");

  TableViewBuilder<byte[]> builder = ...;
  builder = builder.loadConf(config);

  TableView<byte[]> tableView = builder.create();
  

参数:

config - configuration to load

返回:

the TableViewBuilder instance

create

TableView<T> create()
             throws PulsarClientException

Finalize the creation of the TableView instance.

This method will block until the tableView is created successfully or an exception is thrown.

返回:

the TableView instance

抛出:

PulsarClientException - if the tableView creation fails

createAsync

CompletableFuture<TableView<T>> createAsync()

Finalize the creation of the TableView instance in asynchronous mode.

This method will return a CompletableFuture that can be used to access the instance when it's ready.

返回:

the TableView instance

topic

TableViewBuilder<T> topic(String topic)

Set the topic name of the TableView.

参数:

topic - the name of the topic to create the TableView

返回:

the TableViewBuilder builder instance

autoUpdatePartitionsInterval

TableViewBuilder<T> autoUpdatePartitionsInterval(int interval,
 TimeUnit unit)

Set the interval of updating partitions (default: 1 minute).

参数:

interval - the interval of updating partitions

unit - the time unit of the interval

返回:

the TableViewBuilder builder instance

subscriptionName

TableViewBuilder<T> subscriptionName(String subscriptionName)

Set the subscription name of the TableView.

参数:

subscriptionName - the name of the subscription to the topic

返回:

the TableViewBuilder builder instance

cryptoKeyReader

TableViewBuilder<T> cryptoKeyReader(CryptoKeyReader cryptoKeyReader)

Set the CryptoKeyReader to decrypt the message payloads.

参数:

cryptoKeyReader - CryptoKeyReader object

返回:

the TableViewBuilder builder instance

defaultCryptoKeyReader

TableViewBuilder<T> defaultCryptoKeyReader(String privateKey)

Set the default implementation of CryptoKeyReader.

Configure the key reader to be used to decrypt message payloads.

参数:

privateKey - the private key that is always used to decrypt message payloads.

返回:

the TableViewBuilder builder instance

defaultCryptoKeyReader

TableViewBuilder<T> defaultCryptoKeyReader(Map<String,String> privateKeys)

Set the default implementation of CryptoKeyReader.

Configure the key reader to be used to decrypt message payloads.

参数:

privateKeys - the map of private key names and their URIs used to decrypt message payloads.

返回:

the TableViewBuilder builder instance

cryptoFailureAction

TableViewBuilder<T> cryptoFailureAction(ConsumerCryptoFailureAction action)

Set the ConsumerCryptoFailureAction to specify.

参数:

action - the action to take when the decoding fails

返回:

the TableViewBuilder builder instance
