  +--com.solarmetric.kodo.enhance.ApplicationIdTool

public class ApplicationIdTool

extends Object

Generates a class appropriate for use as an application identity class.

Constructor Summary

ApplicationIdTool(Class type, Configuration conf)
Constructs a new ApplicationIdTool capable of generating an object id class for type.

Method Summary

boolean	generateApplicationId() Generates the sourcecode for the application id class; returns false if the class is invalid.
String	getApplicationIdCode() Return the code generated for the application id, or null if invalid class or the generateApplicationId() method has not been called.
ClassMetaData	getClassMetaData() Return the ClassMetaData object for the class, or null if not persistence capable.
boolean	getDieOnInvalid() Return true if this tool is configured to throw an exception on an attempt to generate an id class for a type that does not use application identity.
File	getFile() Return the file that this tool should output to.
PrintStream	getLog() Return the stream being used for logging, or null if none.
Class	getSourceType() Return the type we are generating an application id for.
boolean	isApplicationIdentity() Return true if the class uses application identity, false otherwise.
static void	main(String[] args) Usage: java com.solarmetric.kodo.enhance.JDOEnhancer [option]* <class name | .class file | .jdo file>+
void	setDieOnInvalid(boolean die) Set to true if this tool should throw an exception on an attempt to generate an id class for a type that does not use application identity.
void	setLog(PrintStream log) Set the stream to use for status messages, or null if none.
void	writeApplicationId() Writes the generated code to the proper file.
static void	writeApplicationId(Class type, boolean die, PrintStream log, Configuration conf) Generate an application id source file for the given type.

Constructor Detail

ApplicationIdTool

public ApplicationIdTool(Class type,
                         Configuration conf)
                  throws IOException

Constructs a new ApplicationIdTool capable of generating an object id class for type.

Method Detail

main

public static void main(String[] args)
                 throws IOException

Usage: java com.solarmetric.kodo.enhance.JDOEnhancer [option]* <class name | .class file | .jdo file>+

Where the following options are recognized.

• -properties <properties file>: the path to a Kodo properties file containing information such as the license key, as outlined in Configuration; optional
• -<bean property> <value>: all bean properties of the standard Kodo Configuration can be set by using their names and supplying a value; for example: -licenseKey adslfja83r3lkadf
• -ignoreErrors <true|false>: if false, an exception will be thrown if the tool encounters any class that does not use application identity or uses the identity class of its superclass; defaults to true

If the license key is not specified otherwise, Kodo will check for default preference files with license keys as outlined in DefaultConfiguration.

Each additional argument can be either the full class name of the type to create an id class for, the path to the .class file for the type, or the path to a .jdo file listing one or more types. If a .java file already exists for an application id, it will be backed up to a file named <orig file name>~.

writeApplicationId

public static void writeApplicationId(Class type,
                                      boolean die,
                                      PrintStream log,
                                      Configuration conf)
                               throws IOException

Generate an application id source file for the given type.

Parameters:

type - the type to generate an id for

die - if true, throw an exception if the given type does not need an application identity class

log - the stream to log messages to, or null for no log

conf - the system configuration

Throws:

IOException - if unable to save source

getSourceType

public Class getSourceType()

Return the type we are generating an application id for.

getLog

public PrintStream getLog()

Return the stream being used for logging, or null if none.

setLog

public void setLog(PrintStream log)

Set the stream to use for status messages, or null if none.

getDieOnInvalid

public boolean getDieOnInvalid()

Return true if this tool is configured to throw an exception on an attempt to generate an id class for a type that does not use application identity.

setDieOnInvalid

public void setDieOnInvalid(boolean die)

Set to true if this tool should throw an exception on an attempt to generate an id class for a type that does not use application identity.

isApplicationIdentity

public boolean isApplicationIdentity()

Return true if the class uses application identity, false otherwise.

getClassMetaData

public ClassMetaData getClassMetaData()

Return the ClassMetaData object for the class, or null if not persistence capable.

getApplicationIdCode

public String getApplicationIdCode()

Return the code generated for the application id, or null if invalid class or the generateApplicationId() method has not been called.

getFile

public File getFile()

Return the file that this tool should output to.

generateApplicationId

public boolean generateApplicationId()
                              throws IOException

Generates the sourcecode for the application id class; returns false if the class is invalid.

writeApplicationId

public void writeApplicationId()
                        throws IOException

Writes the generated code to the proper file.
