Field Details

parent

public final CClassInfoParent parent

If this element is global, the element info is considered to be package-level, and this points to the package in which this element lives in.

For local elements, this points to the parent CClassInfo.

Constructor Details

CElementInfo

public CElementInfo(Model model,
 QName tagName,
 CClassInfoParent parent,
 TypeUse contentType,
 XmlString defaultValue,
 XSElementDecl source,
 CCustomizations customizations,
 Locator location)

Creates an element in the given parent.

When using this construction, initContentType(TypeUse, XSElementDecl, XmlString) must not be invoked.

CElementInfo

public CElementInfo(Model model,
 QName tagName,
 CClassInfoParent parent,
 String className,
 CCustomizations customizations,
 Locator location)

Creates an element with a class in the given parent.

When using this construction, the caller must use initContentType(TypeUse, XSElementDecl, XmlString) to fill in the content type later. This is to avoid a circular model construction dependency between buidling a type inside an element and element itself. To build a content type, you need to have for a parent, so we can't take it as a constructor parameter.

Method Details

initContentType

public void initContentType(TypeUse contentType,
 @Nullable
 XSElementDecl source,
 XmlString defaultValue)

getDefaultValue

public String getDefaultValue()

_package

public JPackage _package()

getContentType

public CNonElement getContentType()

Description copied from interface: ElementInfo

Short for getProperty().ref().get(0). The type of the value this element holds. Normally, this is the T of JAXBElement<T>. But if the property is adapted, this is the on-the-wire type. Or if the element has a list of values, then this field represents the type of the individual item.

Specified by:

getContentType in interface ElementInfo<NType,NClass>

See Also:

• ElementInfo.getContentInMemoryType()

getContentInMemoryType

public NType getContentInMemoryType()

Description copied from interface: ElementInfo

T of JAXBElement<T>.

This is tied to the in-memory representation.

Specified by:

getContentInMemoryType in interface ElementInfo<NType,NClass>

See Also:

• ElementInfo.getContentType()

getProperty

public CElementPropertyInfo getProperty()

Description copied from interface: ElementInfo

Gets the object that represents the value property.

Specified by:

getProperty in interface ElementInfo<NType,NClass>

Returns:

non-null.

getScope

public CClassInfo getScope()

Description copied from interface: Element

If non-null, this element is only active inside the given scope.

Specified by:

getScope in interface Element<NType,NClass>

getType

@Deprecated
public NType getType()

Deprecated.

why are you calling a method that returns this?

Description copied from interface: ElementInfo

Returns the representation for JAXBElement<contentInMemoryType>.

This returns the signature in Java and thus isn't affected by the adapter.

Specified by:

getType in interface ElementInfo<NType,NClass>

Specified by:

getType in interface TypeInfo<NType,NClass>

Returns:

always non-null.

getElementName

public QName getElementName()

Description copied from interface: Element

Gets the element name of the class.

Specified by:

getElementName in interface Element<NType,NClass>

Returns:

Always non-null.

toType

public JType toType(Outline o,
 Aspect aspect)

Description copied from interface: NType

Returns the representation of this type in code model.

This operation requires the whole model to be built, and hence it takes Outline.

Under some code generation strategy, some bean classes are considered implementation specific (such as impl.FooImpl class) These classes always have accompanying "exposed" type (such as the Foo interface).

For such Jekyll and Hyde type, the aspect parameter determines which personality is returned.

Specified by:

toType in interface CTypeInfo

Specified by:

toType in interface NType

aspect - If Aspect.IMPLEMENTATION, this method returns the implementation specific class that this type represents. If Aspect.EXPOSED, this method returns the publicly exposed type that this type represents. For ordinary classes, the aspect parameter is meaningless.

See Also:

• NType.toType(Outline, com.sun.tools.xjc.outline.Aspect)

getSqueezedName

public String getSqueezedName()

Returns the "squeezed name" of this element.

See Also:

• CClassInfo.getSqueezedName()

getSubstitutionHead

public CElementInfo getSubstitutionHead()

Description copied from interface: ElementInfo

If this element can substitute another element, return that element.

Substitutability of elements are transitive. can only substitute .

Specified by:

getSubstitutionHead in interface Element<NType,NClass>

Specified by:

getSubstitutionHead in interface ElementInfo<NType,NClass>

Returns:

null if no such element exists.

getSubstitutionMembers

public Collection<CElementInfo> getSubstitutionMembers()

Description copied from interface: ElementInfo

All the s whose ElementInfo.getSubstitutionHead() points to this object.

Specified by:

getSubstitutionMembers in interface ElementInfo<NType,NClass>

Returns:

can be empty but never null.

setSubstitutionHead

public void setSubstitutionHead(CElementInfo substitutionHead)

isBoxedType

public boolean isBoxedType()

Description copied from interface: NType

Returns true iff this type represents a class that has a unboxed form. For example, for String this is false, but for Integer this is true.

Specified by:

isBoxedType in interface NType

fullName

public String fullName()

Description copied from interface: NType

Human readable name of this type.

Specified by:

fullName in interface CClassInfoParent

Specified by:

null if the model is built from sources other than XML Schema (such as DTD.)

canBeReferencedByIDREF

@Deprecated
