Set the wrapped component.- Parameters:
comp
- wrapped component
-
isOptional
public boolean isOptional()
Description copied from interface:IComponent
Check if component is an optional item.- Specified by:
isOptional
in interfaceIComponent
- 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:
hasAttribute
in interfaceIComponent
- 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.- Specified by:
genAttrPresentTest
in interfaceIComponent
- 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.- Specified by:
genAttributeUnmarshal
in interfaceIComponent
- 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.- Specified by:
genAttributeMarshal
in interfaceIComponent
- 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 toILinkable.setLinkages()
.- Specified by:
hasContent
in interfaceIComponent
- Returns:
true
if one or more content values defined for containing element,false
if not
-
genContentPresentTest
public void genContentPresentTest(ContextMethodBuilder mb) throws 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 interfaceIComponent
- Parameters:
mb
- method builder- Throws:
JiBXException
- if configuration error
-
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.- Specified by:
genContentUnmarshal
in interfaceIComponent
- 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.- Specified by:
genContentMarshal
in interfaceIComponent
- Parameters:
mb
- method builder- Throws:
JiBXException
- if error in configuration
-
genNewInstance
public void genNewInstance(ContextMethodBuilder mb) throws JiBXException
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 interfaceIComponent
- 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 interfaceIComponent
- 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 interfaceIComponent
- 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 aString
).- Specified by:
genLoadId
in interfaceIComponent
- Parameters:
mb
- method builder- Throws:
JiBXException
- if configuration error
-
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 interfaceIComponent
- Returns:
- component element name,
null
if no wrapper element
-
setLinkages
public void setLinkages() throws 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 interfaceILinkable
- Throws:
JiBXException
- if error in configuration
-
print
public void print(int depth)
- Specified by:
print
in interfaceIComponent
