Java Architecture for XML Binding 2.3.1 · javax.xml.bind.JAXBElement

JAXB representation of an Xml Element.

This class represents information about an Xml Element from both the element declaration within a schema and the element instance value within an xml document with the following properties

element's xml tag name
value represents the element instance's atttribute(s) and content model
element declaration's declaredType (xs:element @type attribute)
scope of element declaration
boolean nil property. (element instance's xsi:nil attribute)

The declaredType and scope property are the JAXB class binding for the xml type definition.

Scope is either GlobalScope or the Java class representing the complex type definition containing the schema element declaration.

There is a property constraint that if value is null, then nil must be true. The converse is not true to enable representing a nil element with attribute(s). If nil is true, it is possible that value is non-null so it can hold the value of the attributes associated with a nil element.

JAXBElement back to summary

JAXBElement	back to summary
public JAXBElement(QName name, Class<T> declaredType, Class<T> scope, T value) Construct an xml element instance. Parameters name:QName Java binding of xml element tag name declaredType:Class<T> Java binding of xml element declaration's type scope:Class<T> Java binding of scope of xml element declaration. Passing null is the same as passing `GlobalScope.class` value:T Java instance representing xml element's value. See Also `getScope()`, `isTypeSubstituted()`

public JAXBElement(QName name, Class<T> declaredType, Class<T> scope, T value)

Construct an xml element instance.

Parameters

name:QName: Java binding of xml element tag name
declaredType:Class<T>: Java binding of xml element declaration's type
scope:Class<T>: Java binding of scope of xml element declaration. Passing null is the same as passing GlobalScope.class
value:T: Java instance representing xml element's value.

JAXBElement	back to summary
public JAXBElement(QName name, Class<T> declaredType, T value) Construct an xml element instance. This is just a convenience method for `new JAXBElement(name,declaredType,GlobalScope.class,value)`

Method Detail

getDeclaredType	back to summary
public Class<T> getDeclaredType() Returns the Java binding of the xml element declaration's type attribute.

getName	back to summary
public QName getName() Returns the xml element tag name.

getScope back to summary

getScope	back to summary
public Class<T> getScope() Returns scope of xml element declaration. Returns:Class<T> `GlobalScope.class` if this element is of global scope. See Also `isGlobalScope()`

public Class<T> getScope()

Returns scope of xml element declaration.

Returns:Class<T>: GlobalScope.class if this element is of global scope.
See Also: isGlobalScope()

getValue back to summary

getValue	back to summary
public T getValue() Return the content model and attribute values for this element. See `isNil()` for a description of a property constraint when this value is `null`

public T getValue()

Return the content model and attribute values for this element.

See isNil() for a description of a property constraint when this value is null

isGlobalScope	back to summary
public boolean isGlobalScope() Returns true iff this xml element declaration is global.

isNil back to summary

isNil	back to summary
public boolean isNil() Returns `true` iff this element instance content model is nil. This property always returns `true` when `getValue()` is null. Note that the converse is not true, when this property is `true`, `getValue()` can contain a non-null value for attribute(s). It is valid for a nil xml element to have attribute(s).

public boolean isNil()

Returns true iff this element instance content model is nil.

This property always returns true when getValue() is null. Note that the converse is not true, when this property is true, getValue() can contain a non-null value for attribute(s). It is valid for a nil xml element to have attribute(s).

isTypeSubstituted	back to summary
public boolean isTypeSubstituted() Returns true iff this xml element instance's value has a different type than xml element declaration's declared type.

setNil back to summary

setNil	back to summary
public void setNil(boolean value) Set whether this element has nil content. See Also `isNil()`

public void setNil(boolean value)

Set whether this element has nil content.

See Also: isNil()

setValue back to summary

setValue	back to summary
public void setValue(T t) Set the content model and attributes of this xml element. When this property is set to `null`, `isNil()` must by `true`. Details of constraint are described at `isNil()`. See Also `isTypeSubstituted()`

public void setValue(T t)

Set the content model and attributes of this xml element.

When this property is set to null, isNil() must by true. Details of constraint are described at isNil().
