Constructor Detail

ApplicationIdTool

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


ApplicationIdTool

public ApplicationIdTool(OpenJPAConfiguration conf,
                         Class type,
                         ClassMetaData meta)
Constructs a new tool instance capable of generating an object id class for meta.

Method Detail

getIgnoreErrors

public boolean getIgnoreErrors()
Return false 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.


setIgnoreErrors

public void setIgnoreErrors(boolean ignore)
Set to false if this tool should throw an exception on an attempt to generate an id class for a type that does not use application identity.


getCodeFormat

public CodeFormat getCodeFormat()
The code formatter for the generated Java code.


setCodeFormat

public void setCodeFormat(CodeFormat format)
Set the code formatter for the generated Java code.


getDirectory

public File getDirectory()
The directory to write source to. Defaults to the directory of the Java file for the set type. If the given directory does not match the package of the object id, the package structure will be created below the directory.


setDirectory

public void setDirectory(File dir)
The directory to write source to. Defaults to the directory of the Java file for the set type. If the given directory does not match the package of the object id, the package structure will be created below the directory.


getToken

public String getToken()
The token to use to separate stringified primary key field values.


setToken

public void setToken(String token)
The token to use to separate stringified primary key field values.


getWriter

public Writer getWriter()
The writer to write source to, or null to write to default file.


setWriter

public void setWriter(Writer writer)
The writer to write source to, or null to write to default file.


getType

public Class getType()
Return the type we are generating an application id for.


getMetaData

public ClassMetaData getMetaData()
Return metadata for the type we are generating an application id for.


getCode

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


isInnerClass

public boolean isInnerClass()
Returns true if the application identity class should be an inner class.


run

public boolean run()
Generates the sourcecode for the application id class; returns false if the class is invalid.


record

public void record()
            throws IOException
Writes the generated code to the proper file.

Throws:
