Method Detail

genIfPresentTest

public void genIfPresentTest(UnmarshalBuilder mb)
                      throws org.jibx.runtime.JiBXException

Generate test if present code. This generates code that tests if the child is present, leaving the result of the test (zero if missing, nonzero if present) on the stack.

Parameters:

mb - unmarshal method builder

Throws:

org.jibx.runtime.JiBXException - if configuration error

getPropertyName

public String getPropertyName()

Get property name. If the child has an associated property this returns the name of that property.

Returns:

name for child property

isImplicit

public boolean isImplicit()

Check if implicit.

Returns:

true if implicit, false if not

switchProperty

public void switchProperty()

Switch property from "this" to "implicit".

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

hasAttribute

public boolean hasAttribute()

Description copied from interface: IComponent

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

Specified by:

Returns:

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

genAttrPresentTest

public void genAttrPresentTest(ContextMethodBuilder mb)
                        throws org.jibx.runtime.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.

Specified by:

genAttrPresentTest in interface IComponent

Parameters:

mb - method builder

Throws:

org.jibx.runtime.JiBXException - if configuration error

genAttributeUnmarshal

public void genAttributeUnmarshal(ContextMethodBuilder mb)
                           throws org.jibx.runtime.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.

Specified by:

genAttributeUnmarshal in interface IComponent

Parameters:

mb - method builder

Throws:

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

genAttributeMarshal

public void genAttributeMarshal(ContextMethodBuilder mb)
                         throws org.jibx.runtime.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.

Specified by:

genAttributeMarshal in interface IComponent

Parameters:

mb - method builder

Throws:

org.jibx.runtime.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 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

genContentUnmarshal

public void genContentUnmarshal(ContextMethodBuilder mb)
                         throws org.jibx.runtime.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.

Specified by:

genContentUnmarshal in interface IComponent

Parameters:

mb - method builder

Throws:

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

genContentMarshal

public void genContentMarshal(ContextMethodBuilder mb)
                       throws org.jibx.runtime.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.

Specified by:

genContentMarshal in interface IComponent

Parameters:

mb - method builder

Throws:

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

genNewInstance

public void genNewInstance(ContextMethodBuilder mb)

Description copied from interface: IComponent

Generate code to create new instance of object. 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 creating an instance of the object to be unmarshalled, leaving the object reference on the stack.

Specified by:

genNewInstance in interface IComponent

Parameters:

mb - method builder

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

hasId

public boolean hasId()

Description copied from interface: IComponent

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

Specified by:

hasId in interface IComponent

Returns:

true if ID value defined for instances, false if not

public void genLoadId(ContextMethodBuilder mub)
               throws org.jibx.runtime.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).

Specified by:

genLoadId in interface IComponent

Parameters:

mub - method builder

Throws:

org.jibx.runtime.JiBXException - if configuration error

getWrapperName

Specified by:

getWrapperName in interface IComponent

Returns:

component element name, null if no wrapper element

setLinkages

public void setLinkages()
                 throws org.jibx.runtime.JiBXException

Description copied from interface: ILinkable

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.

Specified by:

setLinkages in interface ILinkable

Throws:

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

print

public void print(int depth)

Specified by:

print in interface IComponent
