Description copied from interface: PulsarSerializationSchema

Serializes the incoming element to a specified type.

Specified by:

serialize in interface PulsarSerializationSchema<T>

Parameters:

element - The incoming element to be serialized

open

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

Description copied from interface: PulsarSerializationSchema

Initialization method for the schema. It is called before the actual working methods PulsarSerializationSchema.serialize(Object, TypedMessageBuilder) and thus suitable for one time setup work.

The provided SerializationSchema.InitializationContext can be used to access additional features such as e.g. registering user metrics.

Specified by:

open in interface PulsarSerializationSchema<T>

Parameters:

context - Contextual information that can be used during initialization.

Throws:

Exception

getSchema

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