Method Detail

open

public void open(SerializationSchema.InitializationContext context)

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.

serialize

public byte[] serialize(RowData rowData)

Description copied from interface: SerializationSchema

Serializes the incoming element to a specified type.

Specified by:

serialize in interface SerializationSchema<RowData>

Parameters:

rowData - The incoming element to be serialized

Returns:

The serialized element.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
