Method Detail

modifiers

int modifiers()

Return the modifiers on this class as specified in java.lang.reflect.Modifier.

thisType

Type thisType()

Return the Type of the class represented by this ClassInfo.

isInterface

boolean isInterface()

Return true iff this ClassInfo is an interface.

name

String name()

Return the fully qualified class name for this ClassInfo.

pkgName

String pkgName()

Return the fully qualified package name containing the class represented by this ClassInfo.

className

String className()

Return the class name of the class represented by this ClassInfo relative to pkgName().

superType

Type superType()

Return the Type of the supertype of this class.

impls

List<Type> impls()

Return the list of Types of interfaces implemented by this class. May be empty, but never null.

fieldInfo

Map<String,FieldInfo> fieldInfo()

Return a map from field names to FieldInfo instances for every field defined in this class (not including super types).

findFieldInfo

FieldInfo findFieldInfo(String name)

Find a field with the given name if one exists. Searches this class and all super classes.

methodInfoByName

Map<String,Set<MethodInfo>> methodInfoByName()

Return methodInfo for all methods defined on this class. This does not include inherited methods. Here we return a map from method name to the set of MethodInfo instances for all methods with the same method name. This form is useful for handling method overload resolution.

constructorInfo

Set<MethodInfo> constructorInfo()

findMethodInfo

MethodInfo findMethodInfo(String name,
                        Signature sig)

Find the method (if any) with the given name and Signature in this ClassInfo, or in any superType of this ClassInfo.

findConstructorInfo

MethodInfo findConstructorInfo(Signature sig)

Find the MethodInfo (if any) for a Constructor with the given Signature in this ClassInfo.

isSubclass

boolean isSubclass(ClassInfo info)

Return true iff this is a subclass or subinterface of info.
