Method Details

getAnnotationName

public String getAnnotationName()

Description copied from class: AbstractASTTransformation

If the transform is associated with a single annotation, returns a name suitable for displaying in error messages.

Overrides:

getAnnotationName in class AbstractASTTransformation

Returns:

The simple name of the annotation including the "@" or null if no such name is defined

setCompilationUnit

public void setCompilationUnit(CompilationUnit unit)

Specified by:

setCompilationUnit in interface CompilationUnitAware

visit

public void visit(ASTNode[] nodes,
 SourceUnit source)

Description copied from interface: ASTTransformation

The method is invoked when an AST Transformation is active. For local transformations, it is invoked once each time the local annotation is encountered. For global transformations, it is invoked once for every source unit, which is typically a source file.

Specified by:

visit in interface ASTTransformation

Parameters:

nodes - The ASTnodes when the call was triggered. Element 0 is the AnnotationNode that triggered this annotation to be activated. Element 1 is the AnnotatedNode decorated, such as a MethodNode or ClassNode. For global transformations it is usually safe to ignore this parameter.

source - The source unit being compiled. The source unit may contain several classes. For global transformations, information about the AST can be retrieved from this object.

checkImmutable

public static Object checkImmutable(String className,
 String fieldName,
 Object field)

This method exists to be binary compatible with 1.7 - 1.8.6 compiled code.

checkImmutable

public static Object checkImmutable(Class<?> clazz,
 String fieldName,
 Object field)

For compatibility with pre 2.5 compiled classes

checkImmutable

public static Object checkImmutable(Class<?> clazz,
 String fieldName,
 Object field,
 List<String> knownImmutableFieldNames,
 List<Class> knownImmutableClasses)

checkPropNames

public static void checkPropNames(Object instance,
 Map<String,Object> args)
