Class SchedulerClassInitializer

java.lang.Object
  polyglot.types.SchedulerClassInitializer

All Implemented Interfaces:

LazyClassInitializer, LazyInitializer

public class SchedulerClassInitializer
extends java.lang.Object
implements LazyClassInitializer

A LazyClassInitializer is responsible for initializing members of a class after it has been created. Members are initialized lazily to correctly handle cyclic dependencies between classes. SchedulerClassInitializer ensures that scheduler dependencies are enforced when a ParsedClassType member is accessed.

Method Detail

setClass

public void setClass(ParsedClassType ct)

Description copied from interface: LazyClassInitializer

Set the class type we're initializing.

Specified by:

setClass in interface LazyClassInitializer

fromClassFile

public boolean fromClassFile()

Description copied from interface: LazyClassInitializer

Return true if the class is from a class file.

Specified by:

fromClassFile in interface LazyClassInitializer

initTypeObject

public void initTypeObject()

Description copied from interface: LazyInitializer

Initialize the type object. This must be called once when the object is added to the root-level system resolver, but never before then.

Specified by:

initTypeObject in interface LazyInitializer

isTypeObjectInitialized

public boolean isTypeObjectInitialized()

Description copied from interface: LazyInitializer

Return true if initTypeObject has been called.

Specified by:

isTypeObjectInitialized in interface LazyInitializer

initSuperclass

public void initSuperclass()

Description copied from interface: LazyClassInitializer

Initialize ct's superclass. This method ensures the superclass of the class is initailized to a canonical type, or throws a MissingDependencyException.

Specified by:

initSuperclass in interface LazyClassInitializer

initInterfaces

public void initInterfaces()

Description copied from interface: LazyClassInitializer

Initialize ct's interfaces. This method ensures the interfaces of the class are initailized to canonical types, or throws a MissingDependencyException.

Specified by:

initInterfaces in interface LazyClassInitializer

initMemberClasses

public void initMemberClasses()

Description copied from interface: LazyClassInitializer

Initialize ct's member classes. This method ensures the member classes of the class are initailized to canonical types, or throws a MissingDependencyException.

Specified by:

initMemberClasses in interface LazyClassInitializer

canonicalConstructors

public void canonicalConstructors()

Description copied from interface: LazyClassInitializer

Initialize ct's constructors. This method ensures the list of constructors is populated with canonical ConstructorInstances, or throws a MissingDependencyException.

Specified by:

canonicalConstructors in interface LazyClassInitializer

canonicalMethods

public void canonicalMethods()

Description copied from interface: LazyClassInitializer

Initialize ct's methods. This method ensures the list of methods is populated with canonical MethodInstances, or throws a MissingDependencyException.

Specified by:

canonicalMethods in interface LazyClassInitializer

canonicalFields

public void canonicalFields()

Description copied from interface: LazyClassInitializer

Initialize ct's fields. This method ensures the list of fields is populated with canonical FieldInstances, or throws a MissingDependencyException.

Specified by:

canonicalFields in interface LazyClassInitializer

initConstructors

public void initConstructors()

Description copied from interface: LazyClassInitializer

Initialize ct's constructors. This method ensures the list of fields is populated with (possibly non-canonical) ConstructorInstances, or throws a MissingDependencyException.

Specified by:

initConstructors in interface LazyClassInitializer

initMethods

public void initMethods()

Description copied from interface: LazyClassInitializer

Initialize ct's methods. This method ensures the list of fields is populated with (possibly non-canonical) MethodInstances, or throws a MissingDependencyException.

Specified by:

initMethods in interface LazyClassInitializer

initFields

public void initFields()

Description copied from interface: LazyClassInitializer

Initialize ct's fields. This method ensures the list of fields is populated with (possibly non-canonical) FieldInstances, or throws a MissingDependencyException.

Specified by:

initFields in interface LazyClassInitializer
