All Implemented Interfaces:

Processor, OptionConfiguration

@SupportedSourceVersion(RELEASE_8)
public class JavaCodeStatistics
extends SourceChecker

An annotation processor for counting the size of Java code:

• The number of type parameter declarations and uses.
• The number of array accesses and dimensions in array creations.
• The number of type casts.

To invoke it, use

 javac -proc:only -processor org.checkerframework.common.util.count.JavaCodeStatistics MyFile.java ...

Creates a JavaCodeStatistics.

Method Details

typeProcessingOver

public void typeProcessingOver()

Description copied from class: AbstractTypeProcessor

A method to be called once all the classes are processed.

Subclasses may override this method to do any aggregate analysis (e.g. generate report, persistence) or resource deallocation.

Method AbstractTypeProcessor.getCompilerLog() can be used to access the number of compiler errors.

Overrides:

typeProcessingOver in class AbstractTypeProcessor

createSourceVisitor

protected SourceVisitor<?,?> createSourceVisitor()

Description copied from class: SourceChecker

Provides the SourceVisitor that the checker should use to scan input source trees.

Specified by:

createSourceVisitor in class SourceChecker

Returns:

a SourceVisitor to use to scan source trees

getAnnotationProvider

public AnnotationProvider getAnnotationProvider()

Description copied from class: SourceChecker

Returns the AnnotationProvider (the type factory) associated with this.

Overrides:

getAnnotationProvider in class SourceChecker

Returns:

the AnnotationProvider (the type factory) associated with this
