Package com.dna.jopt.io.importing.container

Class EntityContainerImporter

java.lang.Object

com.dna.jopt.io.importing.container.EntityContainerImporter

All Implemented Interfaces:

IEntityImporter, IJOptImporter<IEntityContainer>, Serializable

@Deprecated(since="7.6.0",
            forRemoval=false)
public class EntityContainerImporter
extends Object
implements IEntityImporter

Deprecated.

The Java container format is replaced by the JSON snapshot. Read a snapshot with OptimizationJSONImporter.read(InputStream) (or one of its update methods) and write it with OptimizationJSONExporter (export(IOptimization, OutputStream)). This class still works as before; each call of read(InputStream) logs one warning.

Reads the Java container format: an IEntityContainer written with Java serialization, for example by EntityContainerExporter.

Method Details

read

@Deprecated(since="7.6.0",
            forRemoval=false)
public Optional<IEntityContainer> read(InputStream fis)

Deprecated.

The Java container format is replaced by the JSON snapshot: use OptimizationJSONImporter.read(InputStream) instead.

Reads a container from a stream of Java serialization.

The stream is read with the allow list of DeserializationFilter: the core's own classes and the JDK and library classes that a container holds. Any other class is refused before it is created. A refusal is logged as an InvalidClassException that names the refused class, and the result is empty, as for any stream that cannot be read.

Each call logs one warning that the Java container format is deprecated.

Specified by:

read in interface IEntityImporter

Specified by:

read in interface IJOptImporter<IEntityContainer>

Parameters:

fis - the stream

Returns:

the container, or empty if the stream could not be read or holds a refused class

getEntityContainer

@Deprecated(since="7.6.0",
            forRemoval=false)
public IEntityContainer getEntityContainer()

Deprecated.

The Java container format is replaced by the JSON snapshot: use OptimizationJSONImporter.read(InputStream) instead.

Returns the container of the last successful read(InputStream).

Specified by:

getEntityContainer in interface IEntityImporter

Returns:

the container, or null if no read has succeeded
