Constructor Detail

NestedStructure

public NestedStructure(IContainer parent,
                       IContextObj objc,
                       boolean ord,
                       boolean choice,
                       boolean ctx,
                       boolean hasobj)

Constructor.

Parameters:

parent - containing binding definition context

objc - current object context

ord - ordered content flag

choice - choice content flag

ctx - define context for structure flag

Method Detail

hasAttribute

public boolean hasAttribute()

Description copied from interface: IComponent

Check if component defines one or more attribute values of the containing element.

Returns:

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

genAttrPresentTest

public void genAttrPresentTest(ContextMethodBuilder mb)
                        throws JiBXException

Description copied from interface: IComponent

Generate code to test for attribute present. This generates code that tests if a child is present as determined by attributes of the containing start tag. It leaves 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 attributes for the containing element.

Parameters:

mb - method builder

Throws:

JiBXException - if configuration error

genAttributeUnmarshal

public void genAttributeUnmarshal(ContextMethodBuilder mb)
                           throws JiBXException

Description copied from interface: IComponent

Generate attribute unmarshalling code. This is called within the code generation for the unmarshaller of the class associated with the containing element. It needs to generate the necessary code for handling the unmarshalling operation, leaving the unmarshalled object reference on the stack.

Parameters:

mb - method builder

Throws:

JiBXException - if error in configuration

genAttributeMarshal

public void genAttributeMarshal(ContextMethodBuilder mb)
                         throws JiBXException

Description copied from interface: IComponent

Generate attribute marshalling code. This is called within the code generation for the marshaller of the class associated with the containing element. It needs to generate the necessary code for handling the marshalling operation, consuming the marshalled object reference from the stack.

Parameters:

mb - method builder

Throws:

JiBXException - if error in configuration

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 IComponent.setLinkages().

Specified by:

hasContent in interface IComponent

Overrides:

hasContent in class NestedBase

Returns:

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

genContentUnmarshal

public void genContentUnmarshal(ContextMethodBuilder mb)
                         throws JiBXException

Description copied from interface: IComponent

Generate element or text unmarshalling code. This is called within the code generation for the unmarshaller of the class associated with the containing element. It needs to generate the necessary code for handling the unmarshalling operation, leaving the unmarshalled object reference on the stack.

Parameters:

mb - method builder

Throws:

JiBXException - if error in configuration

genContentMarshal

public void genContentMarshal(ContextMethodBuilder mb)
                       throws JiBXException

Description copied from interface: IComponent

Generate element or text marshalling code. This is called within the code generation for the marshaller of the class associated with the containing element. It needs to generate the necessary code for handling the marshalling operation, consuming the marshalled object reference from the stack.

Parameters:

mb - method builder

Throws:

JiBXException - if error in configuration

getType

public java.lang.String getType()

Description copied from interface: IComponent

Get type expected by component.

Specified by:

getType in interface IComponent

Overrides:

getType in class NestedBase

Returns:

fully qualified class name of expected type

hasId

public boolean hasId()

Description copied from interface: IComponent

Check if component defines an ID value for instances of context object.

Returns:

true if ID value defined for instances, false if not

genLoadId

public void genLoadId(ContextMethodBuilder mb)
               throws JiBXException

Description copied from interface: IComponent

Generate code to load ID value of instance to stack. The generated code should assume that the top of the stack is the reference for the containing object. It must consume this and leave the actual ID value on the stack (as a String).

Parameters:

mb - method builder

Throws:

JiBXException - if configuration error

checkContentSequence

public boolean checkContentSequence(boolean text)
                             throws JiBXException

Description copied from interface: IComponent

Check sequence of content values. Validates the sequence of content items, ensuring that text values only occur immediately following a required element value (or the start tag for the enclosing element).

Parameters:

text - allow text value flag from last component

Returns:

allow text value as next content component flag

Throws:

JiBXException - if error in configuration

setLinkages

public void setLinkages()
                 throws JiBXException

Description copied from interface: IComponent

Establish and validate linkages between binding components. This is called after the basic binding structures have been set up. All linkages between components must be resolved by this method, in order to prevent problems due to the order of definitions between components. This implies that each component must in turn call the same method for each child component. None of the other method calls defined by this interface are valid until after this call.

Throws:

JiBXException - if error in configuration

print

public void print(int depth)
