getClassHierarchy

Method Detail

getClassLoader

IClassLoader getClassLoader()

Return the object that represents the defining class loader for this class.

Returns:

the object that represents the defining class loader for this class.

isInterface

boolean isInterface()

Is this class a Java interface?

isAbstract

boolean isAbstract()

Returns:

true iff this class is abstract

isPublic

boolean isPublic()

Returns:

true iff this class is public

isPrivate

boolean isPrivate()

Returns:

true iff this class is private

getModifiers

int getModifiers()
                 throws UnsupportedOperationException

Return the integer that encodes the class's modifiers, as defined by the JVM specification

Returns:

the integer that encodes the class's modifiers, as defined by the JVM specification

Throws:

UnsupportedOperationException

getSuperclass

IClass getSuperclass()

Returns:

the superclass, or null if java.lang.Object

Throws:

IllegalStateException - if there's some problem determining the superclass

getDirectInterfaces

Collection<? extends IClass> getDirectInterfaces()

Returns:

Collection of (IClass) interfaces this class directly implements. If this class is an interface, returns the interfaces it immediately extends.

getAllImplementedInterfaces

Collection<IClass> getAllImplementedInterfaces()

Returns:

Collection of (IClass) interfaces this class implements, including all ancestors of interfaces immediately implemented. If this class is an interface, it returns all super-interfaces.

getMethod

IMethod getMethod(Selector selector)

Finds method matching signature. Delegates to superclass if not found.

Parameters:

selector - a method signature

Returns:

IMethod from this class matching the signature; null if not found in this class or any superclass.

getField

IField getField(Atom name)

Finds a field.

Throws:

IllegalStateException - if the class contains multiple fields with name name.

getField

IField getField(Atom name,
              TypeName type)

Finds a field, given a name and a type. Returns null if not found.

getReference

TypeReference getReference()

Returns:

canonical TypeReference corresponding to this class

getSourceFileName

String getSourceFileName()
                         throws NoSuchElementException

Returns:

String holding the name of the source file that defined this class, or null if none found

Throws:

NoSuchElementException - if this class was generated from more than one source file The assumption that a class is generated from a single source file is java specific, and will change in the future. In place of this API, use the APIs in IClassLoader. SJF .. we should think about this deprecation. postponing deprecation for now.

getSource

Reader getSource()
                 throws NoSuchElementException

Returns:

String representing the source file holding this class, or null if not found

Throws:

NoSuchElementException - if this class was generated from more than one source file The assumption that a class is generated from a single source file is java specific, and will change in the future. In place of this API, use the APIs in IClassLoader. SJF .. we should think about this deprecation. postponing deprecation for now.

getClassInitializer

IMethod getClassInitializer()
