Method Detail

matchType

public static boolean matchType(TypePattern typePattern,
                                ClassInfo classInfo)

Matches a type.

Parameters:

typePattern - the pattern to try to parse against

classInfo - the info of the class

Returns:

matchSuperClasses

public static boolean matchSuperClasses(ClassInfo classInfo,
                                        TypePattern pattern)

Tries to finds a parse at some superclass in the hierarchy.

Only checks for a class parse to allow early filtering.

Recursive.

Parameters:

classInfo - the class info

pattern - the type pattern

Returns:

boolean

matchInterfaces

public static boolean matchInterfaces(ClassInfo[] interfaces,
                                      ClassInfo classInfo,
                                      TypePattern pattern)

Tries to finds a parse at some interface in the hierarchy.

Only checks for a class parse to allow early filtering.

Recursive.

Parameters:

interfaces - the interfaces

classInfo - the class info

pattern - the type pattern

Returns:

boolean

createMemberInfo

public static MemberInfo createMemberInfo(Class targetClass,
                                          String withinMethodName,
                                          String withinMethodSignature)

Creates a member info instance based on the signature etc.

Parameters:

targetClass -

withinMethodName -

withinMethodSignature -

Returns:

a member info instance

isMethodStatic

public static boolean isMethodStatic(MethodInfo methodInfo)

Checks if a method is static or not.

Parameters:

methodInfo - the info for the method

Returns:

boolean

implementsInterface

public static boolean implementsInterface(ClassInfo classInfo,
                                          String interfaceName)

Checks if a class implements a certain inteface, somewhere up in the class hierarchy.

Parameters:

classInfo -

interfaceName -

Returns:

true if we have a parse else false

extendsSuperClass

public static boolean extendsSuperClass(ClassInfo classInfo,
                                        String className)

Checks if a class has a certain class as super class, somewhere up in the class hierarchy.

Parameters:

classInfo - the meta-data for the class to parse

className - the name of the super class

Returns:

true if we have a parse else false
