Method Detail

open

public void open(SerializationSchema.InitializationContext context)
          throws Exception

Description copied from interface: SerializationSchema

Initialization method for the schema. It is called before the actual working methods SerializationSchema.serialize(Object) 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 SerializationSchema<RowData>

Parameters:

context - Contextual information that can be used during initialization.

Throws:

Exception

serialize

public byte[] serialize(RowData element)

Description copied from interface: SerializationSchema

Serializes the incoming element to a specified type.

Specified by:
