Method Detail

applicable

public boolean applicable(AutoValueExtension.Context context)

Description copied from class: AutoValueExtension

Determines whether this Extension applies to the given context.

Overrides:

applicable in class AutoValueExtension

Parameters:

context - The Context of the code generation for this class.

Returns:

true if this Extension should be applied in the given context. If an Extension returns false for a given class, it will not be called again during the processing of that class.

generateClass

public String generateClass(AutoValueExtension.Context context,
                            String className,
                            String classToExtend,
                            boolean isFinal)

Description copied from class: AutoValueExtension

Returns the generated source code of the class named className to extend classToExtend, or null if this extension does not generate a class in the hierarchy. If there is a generated class, it should be final if isFinal is true; otherwise it should be abstract. The returned string should be a complete Java class definition of the class className in the package context.packageName().

The returned string will typically look like this:

 package <package>;
 ...
 <finalOrAbstract> class <className> extends <classToExtend> {...}
 

Here, <package> is AutoValueExtension.Context.packageName(); <finalOrAbstract> is the keyword final if isFinal is true or abstract otherwise; and <className> and <classToExtend> are the values of this method's parameters of the same name.

Specified by:

generateClass in class AutoValueExtension

Parameters:

context - The AutoValueExtension.Context of the code generation for this class.

className - The simple name of the resulting class. The returned code will be written to a file named accordingly.

classToExtend - The simple name of the direct parent of the generated class. This could be the AutoValue generated class, or a class generated as the result of another Extension.

isFinal - True if this class is the last class in the chain, meaning it should be marked as final. Otherwise it should be marked as abstract.

Returns:

The source code of the generated class, or null if this extension does not generate a class in the hierarchy.
