TetradSerializableUtils(String serializableScope, String currentDirectory, String archiveDirectory)	Blank constructor.

Method Summary

Modifier and Type	Method	Description
void	archiveCurrentDirectory()	Creates a zip archive of the currently serialized files in getCurrentDirectory(), placing the archive in getArchiveDirectory().
void	checkNestingOfFields()	Checks all of the classes in the serialization scope that implement TetradSerializable to make sure all of their fields are either themselves (a) primitive, (b) TetradSerializable, or (c) assignable from types designated as safely serializable by virtue of being included in the safelySerializableTypes array (see), or are arrays whose lowest order component types satisfy either (a), (b), or (c).
void	clearArchiveDirectory()	Clears the archive directory.
void	deserializeArchivedVersions()	Deserializes examplars stored in archives in getArchiveDirectory().
void	deserializeCurrentDirectory()	Deserializes all files in the given directory, as a test to make sure they can all be deserialized.
void	serializeCurrentDirectory()	Finds all classes inside the stated scope that implement TetradSerializable and serializes them out to the getCurrentDirectory() directory.

Method Details

checkNestingOfFields

public void checkNestingOfFields()

Checks all of the classes in the serialization scope that implement TetradSerializable to make sure all of their fields are either themselves (a) primitive, (b) TetradSerializable, or (c) assignable from types designated as safely serializable by virtue of being included in the safelySerializableTypes array (see), or are arrays whose lowest order component types satisfy either (a), (b), or (c). Safely serializable classes in the Java API currently include collections classes, plus String and Class. Collections classes are included, since their types will be syntactically checkable in JDK 1.5. String and Class are members of a broader type of Class whose safely can by checked by making sure there is no way to pass into them via constructor or method argument any object that is not TetradSerializable or safely serializable. But it's easy enough now to just make a list.

serializeCurrentDirectory

public void serializeCurrentDirectory()
                               throws RuntimeException

Finds all classes inside the stated scope that implement TetradSerializable and serializes them out to the getCurrentDirectory() directory. Abstract methods and interfaces are skipped over. For all other classes C, it is assumed that C has a static constructor of the following form:

     public static C serializableInstance() {
         // Returns an instance of C. May be a mind-numbingly simple
         // instance, no need to get fancy.
     }
 

The instance returned may be mind-numbingly simple; there is no need to get fancy. It may change over time. The point is to make sure that instances serialized out with earlier versions load with the currentDirectory version.

Throws:

RuntimeException - if clazz cannot be serialized. This exception has an informative message and wraps the originally thrown exception as root cause.

clearArchiveDirectory

public void clearArchiveDirectory()

Clears the archive directory.

deserializeCurrentDirectory

public void deserializeCurrentDirectory()
                                 throws RuntimeException

Deserializes all files in the given directory, as a test to make sure they can all be deserialized.

Throws:

RuntimeException - if clazz cannot be serialized. This exception has an informative message and wraps the originally thrown exception as root cause.

archiveCurrentDirectory

public void archiveCurrentDirectory()
                             throws RuntimeException

Creates a zip archive of the currently serialized files in getCurrentDirectory(), placing the archive in getArchiveDirectory().

Throws:

RuntimeException - if clazz cannot be serialized. This exception has an informative message and wraps the originally thrown exception as root cause.

deserializeArchivedVersions

public void deserializeArchivedVersions()
                                 throws RuntimeException

Deserializes examplars stored in archives in getArchiveDirectory().

Throws:

RuntimeException - if clazz cannot be serialized. This exception has an informative message and wraps the originally thrown exception as root cause.
