OMInformationItem, OMSerializable

All Known Subinterfaces:

OMComment, OMDocType, OMElement, OMEntityReference, OMProcessingInstruction, OMSourcedElement, OMText, SOAPBody, SOAPEnvelope, SOAPFault, SOAPFaultClassifier, SOAPFaultCode, SOAPFaultDetail, SOAPFaultNode, SOAPFaultReason, SOAPFaultRole, SOAPFaultSubCode, SOAPFaultText, SOAPFaultValue, SOAPHeader, SOAPHeaderBlock

public interface OMNode
extends OMSerializable

Defines the base interface used by most of the XML object model within Axis.

This tree model for XML captures the idea of deferring the construction of child nodes until they are needed. The isComplete function identifies whether or not a particular node has been fully parsed. A node may not be fully parsed, for example, if all of the children of an element have not yet been parsed.

In comparison to DOM, in this model, you will not find document fragments, or entities. In addition, while OMDocument and OMAttribute exist, neither is an extension of OMNode.

Field Detail

ELEMENT_NODE

static final short ELEMENT_NODE

The node is an Element.

getType(), Constant Field Values

TEXT_NODE

static final short TEXT_NODE

The node is a Text node.

getType(), Constant Field Values

CDATA_SECTION_NODE

static final short CDATA_SECTION_NODE

Method Detail

getParent

OMContainer getParent()

Returns the parent containing node.

Returns the parent container, which may be either an OMDocument or OMElement.

Returns:

The OMContainer of the node.

getNextOMSibling

OMNode getNextOMSibling()
                 throws OMException

Returns the next sibling in document order.

Returns:

Returns the next sibling in document order.

Throws:

OMException

detach

OMNode detach()
       throws OMException

Removes a node (and all of its children) from its containing parent.

Removes a node from its parent. Please note that this will not handle the namespaces. For example, if there you have used a namespace within the detaching node and which is defined outside the detaching node, user has to handle it manually.

Returns:

The detached node. This is always the instance on which this method is invoked.

Throws:

OMException

discard

void discard()
      throws OMException

Discards a node.

Discard goes to the parser level and if the element is not completely built, then it will be completely skipped at the parser level.

Throws:

OMException

insertSiblingAfter

void insertSiblingAfter(OMNode sibling)
                 throws OMException

Inserts a new sibling after the current node. The current node must have a parent for this operation to succeed. If the node to be inserted has a parent, then it will first be detached.

Parameters:

sibling - The node that will be added after the current node.

Throws:

OMException - if the current node has no parent

insertSiblingBefore

void insertSiblingBefore(OMNode sibling)
                  throws OMException

Inserts a sibling just before the current node. The current node must have a parent for this operation to succeed. If the node to be inserted has a parent, then it will first be detached.

Parameters:

sibling - The node that will be added before the current node.

Throws:

OMException - if the current node has no parent

getType

int getType()

Returns the type of node.

Returns:

Returns one of ELEMENT_NODE, TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, DTD_NODE, PI_NODE, ENTITY_REFERENCE_NODE or SPACE_NODE.

getPreviousOMSibling

OMNode getPreviousOMSibling()

Gets the previous sibling.

Returns:

Returns node.

buildWithAttachments

void buildWithAttachments()

Builds itself with the OMText binary content. AXIOM supports two levels of deffered building. First is deffered building of AXIOM using StAX. Second level is the deffered building of attachments. AXIOM reads in the attachements from the stream only when user asks by calling getDataHandler(). build() method builds the OM without the attachments. buildAll() builds the OM together with attachement data. This becomes handy when user wants to free the input stream.
