public static MethodAnnotation fromCalledMethod(DismantleBytecode visitor)

Factory method to create a MethodAnnotation from a method called by the instruction the given visitor is currently visiting.

Parameters:

visitor - the visitor

Returns:

the MethodAnnotation representing the called method

fromForeignMethod

public static MethodAnnotation fromForeignMethod(@SlashedClassName
                                 String className,

methodName - name of the method

methodSig - signature of the method

accessFlags - the access flags of the method

Returns:

the MethodAnnotation

fromForeignMethod

public static MethodAnnotation fromForeignMethod(String className,
                                 String methodName,
                                 String methodSig,
                                 boolean isStatic)

Factory method to create the MethodAnnotation from the classname, method name, signature, etc. The method tries to look up source line information for the method.

Parameters:

className - name of the class containing the method

methodName - name of the method

methodSig - signature of the method

isStatic - true if the method is static, false otherwise

Returns:

the MethodAnnotation

fromCalledMethod

public static MethodAnnotation fromCalledMethod(String className,
                                String methodName,
                                String methodSig,
                                boolean isStatic)

Create a MethodAnnotation from a method that is not directly accessible. We will use the repository to try to find its class in order to populate the information as fully as possible.

Parameters:

className - class containing called method

methodName - name of called method

methodSig - signature of called method

isStatic - true if called method is static

Returns:

the MethodAnnotation for the called method

fromXMethod

Create a MethodAnnotation from an XMethod.

Parameters:

xmethod - the XMethod

Returns:

the MethodAnnotation

accept

public void accept(BugAnnotationVisitor visitor)

Description copied from interface: BugAnnotation

Accept a BugAnnotationVisitor.

Parameters:

visitor - the visitor to accept

formatPackageMember

protected String formatPackageMember(String key,
                         ClassAnnotation primaryClass)

Description copied from class: PackageMemberAnnotation

Do default and subclass-specific formatting.

Specified by:

formatPackageMember in class PackageMemberAnnotation

Parameters:

key - the key specifying how to do the formatting

primaryClass - TODO

getNameInClass

public String getNameInClass(ClassAnnotation primaryClass)

Get the "full" method name. This is a format which looks sort of like a method signature that would appear in Java source code.

getSignatureInClass

public String getSignatureInClass(ClassAnnotation primaryClass)

getNameInClass

public String getNameInClass(boolean shortenPackages,
                    boolean useJVMMethodName,
                    boolean hash)

getNameInClass

public String getNameInClass(boolean shortenPackages,
                    boolean useJVMMethodName,
                    boolean hash,
                    boolean omitMethodName)

Get the "full" method name. This is a format which looks sort of like a method signature that would appear in Java source code. note: If shortenPackeges==true, this will return the same value as getNameInClass(), except that method caches the result and this one does not. Calling this one may be slow.
