Constructor Details

CFGProcessor

public CFGProcessor(String className,
 String methodName)

Create a CFG processor.

Parameters:

className - the qualified name of class that defines the method

methodName - the name of the method to generate the CFG for

Method Details

getCFGProcessResult

public final @Nullable CFGProcessor.CFGProcessResult getCFGProcessResult()

Returns the CFG process result.

Returns:

result of cfg process

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

createTreePathScanner

protected TreePathScanner<?,?> createTreePathScanner(CompilationUnitTree root)

Description copied from class: BasicTypeProcessor

Create a TreePathScanner at the given root.

Specified by:

createTreePathScanner in class BasicTypeProcessor

Parameters:

root - where to start the tree traversal

Returns:

a TreePathScanner at the given root

getSupportedSourceVersion

public SourceVersion getSupportedSourceVersion()

Specified by:

getSupportedSourceVersion in interface Processor

Overrides:

getSupportedSourceVersion in class AbstractProcessor
