Interface SOAPElement

All Superinterfaces:
Element, Node, Node
All Known Subinterfaces:
Detail, DetailEntry, SOAPBody, SOAPBodyElement, SOAPEnvelope, SOAPFault, SOAPFaultElement, SOAPHeader, SOAPHeaderElement

public interface SOAPElement
extends Node, Element

An object representing an element of a SOAP message that is allowed but not specifically prescribed by a SOAP specification. This interface serves as the base interface for those objects that are specifically prescribed by a SOAP specification.

Methods in this interface that are required to return SAAJ specific objects may "silently" replace nodes in the tree as required to successfully return objects of the correct type. See getChildElements() and javax.xml.soap for details.

addChildElement

public SOAPElement addChildElement(String localName,
                                   String prefix)
                            throws SOAPException
Creates a new SOAPElement object initialized with the specified local name and prefix and adds the new element to this SOAPElement object.

Parameters:
localName - a String giving the local name for the new element
prefix - a String giving the namespace prefix for the new element
Returns:
the new SOAPElement object that was created
Throws:
SOAPException - if there is an error in creating the SOAPElement object

addChildElement

public SOAPElement addChildElement(String localName,
                                   String prefix,
                                   String uri)
                            throws SOAPException
Creates a new SOAPElement object initialized with the specified local name, prefix, and URI and adds the new element to this SOAPElement object.

Parameters:
localName - a String giving the local name for the new element
prefix - a String giving the namespace prefix for the new element
uri - a String giving the URI of the namespace to which the new element belongs
Returns:
the new SOAPElement object that was created
Throws:
SOAPException - if there is an error in creating the SOAPElement object

addChildElement

public SOAPElement addChildElement(SOAPElement element)
                            throws SOAPException
Add a SOAPElement as a child of this SOAPElement instance. The SOAPElement is expected to be created by a SOAPElementFactory. Callers should not rely on the element instance being added as is into the XML tree. Implementations could end up copying the content of the SOAPElement passed into an instance of a different SOAPElement implementation. For instance if addChildElement() is called on a SOAPHeader, element will be copied into an instance of a SOAPHeaderElement.

The fragment rooted in element is either added as a whole or not at all, if there was an error.

The fragment rooted in element cannot contain elements named "Envelope", "Header" or "Body" and in the SOAP namespace. Any namespace prefixes present in the fragment should be fully resolved using appropriate namespace declarations within the fragment itself.

Parameters:
element - the SOAPElement to be added as a new child
Returns:
an instance representing the new SOAP element that was actually added to the tree.
Throws:
SOAPException - if there was an error in adding this element as a child

removeContents

public void removeContents()
Detaches all children of this SOAPElement.

This method is useful for rolling back the construction of partially completed SOAPHeaders and SOAPBodys in preparation for sending a fault when an error condition is detected. It is also useful for recycling portions of a document within a SOAP message.

Since:
SAAJ 1.2

addTextNode

public SOAPElement addTextNode(String text)
                        throws SOAPException
Creates a new Text object initialized with the given String and adds it to this SOAPElement object.

Parameters:
text - a String object with the textual content to be added
Returns:
the SOAPElement object into which the new Text object was inserted
Throws:
SOAPException - if there is an error in creating the new Text object

addAttribute

public SOAPElement addAttribute(Name name,
                                String value)
                         throws SOAPException
Adds an attribute with the specified name and value to this SOAPElement object.

Parameters:
name - a Name object with the name of the attribute
value - a String giving the value of the attribute
Returns:
the SOAPElement object into which the attribute was inserted
Throws:

                                           String uri)
                                    throws SOAPException
Adds a namespace declaration with the specified prefix and URI to this SOAPElement object.

Parameters:
prefix - a String giving the prefix of the namespace
uri - a String giving the uri of the namespace
Returns:
the SOAPElement object into which this namespace declaration was inserted.
Throws:
SOAPException - if there is an error in creating the namespace

getAttributeValue

public String getAttributeValue(Name name)
Returns the value of the attribute with the specified name.

Parameters:
name - a Name object with the name of the attribute
Returns:
a String giving the value of the specified attribute

getAllAttributes

public Iterator getAllAttributes()

Returns:
an iterator over the names of the attributes

getNamespaceURI

public String getNamespaceURI(String prefix)
Returns the URI of the namespace that has the given prefix.

Parameters:
prefix - a String giving the prefix of the namespace for which to search
Returns:
a String with the uri of the namespace that has the given prefix

getNamespacePrefixes

public Iterator getNamespacePrefixes()

getElementName

public Name getElementName()
Returns the name of this SOAPElement object.

Returns:
a Name object with the name of this SOAPElement object

removeAttribute

public boolean removeAttribute(Name name)
Removes the attribute with the specified name.

true if the namespace declaration was removed successfully; false if it was not

getChildElements

public Iterator getChildElements()
Returns an Iterator over all the immediate child Nodes of this element. This includes javax.xml.soap.Text objects as well as SOAPElement objects.

Calling this method may cause child Element, SOAPElement and org.w3c.dom.Text nodes to be replaced by SOAPElement, SOAPHeaderElement, SOAPBodyElement or javax.xml.soap.Text nodes as appropriate for the type of this parent node. As a result the calling application must treat any existing references to these child nodes that have been obtained through DOM APIs as invalid and either discard them or refresh them with the values returned by this Iterator. This behavior can be avoided by calling the equivalent DOM APIs. See javax.xml.soap for more details.

Returns:
an iterator with the content of this SOAPElement object

getChildElements

public Iterator getChildElements(Name name)
Returns an Iterator over all the immediate child Nodes of this element with the specified name. All of these children will be SOAPElement nodes.

Calling this method may cause child Element, SOAPElement and org.w3c.dom.Text nodes to be replaced by SOAPElement, SOAPHeaderElement, SOAPBodyElement or javax.xml.soap.Text nodes as appropriate for the type of this parent node. As a result the calling application must treat any existing references to these child nodes that have been obtained through DOM APIs as invalid and either discard them or refresh them with the values returned by this Iterator. This behavior can be avoided by calling the equivalent DOM APIs. See javax.xml.soap for more details.

Parameters:
name - a Name object with the name of the child elements to be returned
Returns:
an Iterator object over all the elements in this SOAPElement object with the specified name

setEncodingStyle

public void setEncodingStyle(String encodingStyle)
                      throws SOAPException
Sets the encoding style for this SOAPElement object to one specified.
