Constructor Detail

NestedBase

public NestedBase(IContainer contain,
                  IContextObj objc,
                  boolean ord,
                  boolean flex,
                  boolean defc)

Constructor.

Parameters:

contain - containing binding definition context

objc - current object context

ord - ordered content flag

flex - flexible element handling flag

defc - define context for structure flag

Method Detail

setObjectContext

public void setObjectContext(IContextObj objc)

Set the object context.

Parameters:

objc - object context

getAttributes

public ArrayList getAttributes()

Get the attribute children of this mapping.

Returns:

list of attribute children (null if none; should not be modified)

getContents

public ArrayList getContents()

Get the content children of this mapping.

Returns:

list of content children (should not be modified)

addComponent

public void addComponent(IComponent comp)

Add child component to nested structure. All components are initially assumed to contain content. When ILinkable.setLinkages() is called the components are checked to determine whether they actually supply attribute(s), content, or both.

Parameters:

comp - child component to be added to structure

isFlexible

public boolean isFlexible()

Check if flexible unmarshalling.

Returns:

flexible flag

isContentOrdered

public boolean isContentOrdered()

Description copied from interface: IContainer

Check if content children are ordered.

Specified by:

isContentOrdered in interface IContainer

Returns:

true if ordered, false if not

hasNamespaces

public boolean hasNamespaces()

getBindingRoot

public BindingDefinition getBindingRoot()

Description copied from interface: IContainer

Get root of binding definition.

Specified by:

getBindingRoot in interface IContainer

Returns:

binding definition root

getDefinitionContext

public DefinitionContext getDefinitionContext()

Description copied from interface: IContainer

Get definition context for binding element.

Specified by:

getDefinitionContext in interface IContainer

Returns:

binding definition context

isOptional

public boolean isOptional()

Description copied from interface: IComponent

Check if component is an optional item.

Specified by:

isOptional in interface IComponent

Returns:

true if optional, false if required

hasContent

public boolean hasContent()

Description copied from interface: IComponent

Check if component defines one or more elements or text values as children of the containing element. This method is only valid after the call to ILinkable.setLinkages().

Specified by:

hasContent in interface IComponent

Returns:

true if one or more content values defined for containing element, false if not

genContentPresentTest

public void genContentPresentTest(ContextMethodBuilder mb)
                           throws org.jibx.runtime.JiBXException

Description copied from interface: IComponent

Generate code to test for content present. This generates code that tests if a required element is present, leaving the result of the test (zero if missing, nonzero if present) on the stack. This call is only valid if this component has one or more content components for the containing element.

Specified by:

genContentPresentTest in interface IComponent

Parameters:

mb - method builder

Throws:

org.jibx.runtime.JiBXException - if configuration error

getType

public String getType()

Description copied from interface: IComponent

Get type expected by component.

Specified by:

getType in interface IComponent

Returns:

fully qualified class name of expected type

getWrapperName

public NameDefinition getWrapperName()

Description copied from interface: IComponent

Get element wrapper name. If the component defines an element as the container for content, this returns the name information for that element.

Specified by:

getWrapperName in interface IComponent

Returns:

component element name, null if no wrapper element

unmarshal

public void unmarshal(org.jibx.runtime.impl.UnmarshallingContext ctx)
               throws org.jibx.runtime.JiBXException

Unmarshal common container attributes.

Parameters:

ctx - unmarshalling context information

Throws:

org.jibx.runtime.JiBXException - if error in unmarshalling

getStyleDefault

public int getStyleDefault()
