Class SourceCode

java.lang.Object
  extended by org.apache.openjpa.persistence.util.SourceCode

public class SourceCode
extends Object

A utility to help writing Java Source code dynamically. Provides basic elements of Java Source Code e.g. Package, Class, Field, Method, Import, Annotation, Argument. Mutator methods return the operating element for easy chaining.

Constructor Detail

SourceCode

public SourceCode(String c)
Create source code for a top-level class with given fully-qualified class name.

Method Detail

getTopLevelClass

public SourceCode.Class getTopLevelClass()
Gets the top level class represented by this receiver.


getPackage

public SourceCode.Package getPackage()

setTabSize

public SourceCode setTabSize(int t)
Sets the tab size. Tabs are always written as spaces.


getOrCreateImport

org.apache.openjpa.persistence.util.SourceCode.ClassName getOrCreateImport(String name)

Parameters:
name - fully-qualified name of a class
Returns:
an existing class name instance or a new one.
