Method Detail

serialize

void serialize(T element,
               org.apache.pulsar.client.api.TypedMessageBuilder<T> messageBuilder)

Serializes the incoming element to a specified type.

Parameters:

element - The incoming element to be serialized

open

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

Initialization method for the schema. It is called before the actual working methods 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.

Parameters:

context - Contextual information that can be used during initialization.

Throws:

Exception
