hasChildNodes

public boolean hasChildNodes()

Description copied from interface: Node

Returns whether this node has any children.

Specified by:

hasChildNodes in interface Node

Returns:

true if this node has any children, false otherwise.

cloneNode

public Node cloneNode(boolean deep)

Description copied from interface: Node

Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent; ( parentNode is null.).
Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning an Attribute directly, as opposed to be cloned as part of an Element cloning operation, returns a specified attribute ( specified is true). Cloning any other type of node simply returns a copy of this node.
Note that cloning an immutable subtree results in a mutable copy, but the children of an EntityReference clone are readonly . In addition, clones of unspecified Attr nodes are specified. And, cloning Document, DocumentType, Entity, and Notation nodes is implementation dependent.

Specified by:

cloneNode in interface Node

Returns:

The duplicate node.

hasSlot

public boolean hasSlot(String name,
                       DynEnv env)

Overrides:

public Object getSlot(String name,
                      DynEnv env)

Overrides:

setSlot

public void setSlot(String name,
                    Object value,
                    DynEnv env)

Description copied from class: DynamicObject

addEventListener

public void addEventListener(String type,
                             EventListener listener,
                             boolean useCapture)

For the list of supported event types, see ThePilot.addPersistentDOMEventListener(java.lang.String, org.w3c.dom.events.EventListener, boolean)

Specified by:

addEventListener in interface EventTarget

removeEventListener

public void removeEventListener(String type,
                                EventListener listener,
                                boolean useCapture)

Description copied from interface: EventTarget

This method allows the removal of event listeners from the event target. If an EventListener is removed from an EventTarget while it is processing an event, it will not be triggered by the current actions. EventListeners can never be invoked after being removed.
Calling removeEventListener with arguments which do not identify any currently registered EventListener on the EventTarget has no effect.

Specified by:

removeEventListener in interface EventTarget

dispatchEvent

public boolean dispatchEvent(Event evt)

Description copied from interface: EventTarget

This method allows the dispatch of events into the implementations event model. Events dispatched in this manner will have the same capturing and bubbling behavior as events dispatched directly by the implementation. The target of the event is the EventTarget on which dispatchEvent is called.

Specified by:

dispatchEvent in interface EventTarget

Returns:

The return value of dispatchEvent indicates whether any of the listeners which handled the event called preventDefault. If preventDefault was called the value is false, else the value is true.

contains

public boolean contains(DNode toFind)

getDParent

protected DNode getDParent()

setInnerText

public void setInnerText(String text)

setOuterText

public void setOuterText(String text)

getOuterText

public String getOuterText()

getInnerText

public String getInnerText()

getAll

public DAllList getAll()

normalize

public void normalize()

Description copied from interface: Node

Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.In cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes.

Specified by:

normalize in interface Node

isSupported

public boolean isSupported(String feature,
                           String version)

Description copied from interface: Node

Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

Specified by:

isSupported in interface Node

Returns:

Returns true if the specified feature is supported on this node, false otherwise.

getNamespaceURI

public String getNamespaceURI()

Description copied from interface: Node

The namespace URI of this node, or null if it is unspecified.
This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.Per the Namespaces in XML Specification an attribute does not inherit its namespace from the element it is attached to. If an attribute is not explicitly given a namespace, it simply has no namespace.

Specified by:

getNamespaceURI in interface Node

getPrefix

public String getPrefix()

Description copied from interface: Node

The namespace prefix of this node, or null if it is unspecified.
Note that setting this attribute, when permitted, changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.
Note also that changing the prefix of an attribute that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespaceURI and localName do not change.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Specified by:

getPrefix in interface Node

setPrefix

public void setPrefix(String prefix)

Specified by:

setPrefix in interface Node

getLocalName

public String getLocalName()

Description copied from interface: Node

Returns the local part of the qualified name of this node.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Specified by:

getLocalName in interface Node

hasAttributes

public boolean hasAttributes()

Description copied from interface: Node

Returns whether this node (if it is an element) has any attributes.

Specified by:

hasAttributes in interface Node

Returns:

true if this node has any attributes, false otherwise.

getDynamicScopeParent

public Object getDynamicScopeParent()

Description copied from class: DynamicObject

This is only relevant to support scope chain during event handler execution. In ideal world this should always return null

Overrides:

getDynamicScopeParent in class DynamicObject

getDynamicValue

public Object getDynamicValue(String name,
                              DynEnv env)

Description copied from class: DynamicObject

Returns the `key' field or Defs.NOT_FOUND if `name' does not exist. Returns `FUNCTION_MARK' if `name' represent a function that can be invoke via execDynamicMethod. Note that returned `null' indicates that value is present but set to null.

Overrides:

getDynamicValue in class DynamicObject

setDynamicValue

public int setDynamicValue(String name,
                           Object value,
                           DynEnv env)

Description copied from class: DynamicObject

Set field `name' to `value'. Use `env' to unwrap `value' to a particular type or store it as is

Overrides:

setDynamicValue in class DynamicObject

Returns:

SETD_NOT_FOUND if fied `name' is absent, SETD_IGNORE if field exist but set is ignored SETD_OK if set opeartion was ok

execDynamicMethod

public Object execDynamicMethod(String name,
                                Object[] args,
                                DynEnv env)

Description copied from class: DynamicObject

Perform function-like actions for `name' with the given args. Returns the result or Defs.NOT_FOUND if name is not associated with function action. Should return result of env.wrapVoid() to indicate method without return value. Use `env' to unwrap `args' elements to a particular type.

Overrides:

execDynamicMethod in class DynamicObject
