Method Detail

getTargetTopic

public Optional<String> getTargetTopic(T element)

Deprecated.

Description copied from interface: PulsarContextAware

Returns the topic that the presented element should be sent to.

Specified by:

getTargetTopic in interface PulsarContextAware<T>

getSchema

public org.apache.pulsar.client.api.Schema<T> getSchema()

Deprecated.

Specified by:

getSchema in interface PulsarContextAware<T>

getProducedType

public org.apache.flink.api.common.typeinfo.TypeInformation<T> getProducedType()

Deprecated.

Specified by:

getProducedType in interface org.apache.flink.api.java.typeutils.ResultTypeQueryable<T>

open

public void open(org.apache.flink.api.common.serialization.DeserializationSchema.InitializationContext context)
          throws Exception

Deprecated.

Specified by:

open in interface PulsarDeserializationSchema<T>

Throws:

Exception

isEndOfStream

public boolean isEndOfStream(T nextElement)

Deprecated.

Description copied from interface: PulsarDeserializationSchema

Method to decide whether the element signals the end of the stream. If true is returned the element won't be emitted.

Specified by:

isEndOfStream in interface PulsarDeserializationSchema<T>

Parameters:

nextElement - The element to test for the end-of-stream signal.

Returns:

True, if the element signals end of stream, false otherwise.

deserialize

public T deserialize(org.apache.pulsar.client.api.Message<T> message)
              throws IOException

Deprecated.

Description copied from interface: PulsarDeserializationSchema

Deserializes the Pulsar message.

Can output multiple records through the Collector. Note that number and size of the produced records should be relatively small. Depending on the source implementation records can be buffered in memory or collecting records might delay emitting checkpoint barrier.

Specified by:

deserialize in interface PulsarDeserializationSchema<T>

Parameters:

message - The message, as a byte array.

Throws:

IOException
