All Implemented Interfaces:

VoiceXmlNode, XmlNode, org.w3c.dom.Node

public final class Initial
extends AbstractXmlNode

Declares initial logic upon entry into a (mixed initiative) form.

In a typical mixed initiative form, an <initial> element is visited when the user is initially being prompted for form-wide information, and has not yet entered into the directed mode where each field is visited individually. Like input items, it has prompts, catches, and event counters. Unlike input items, <initial> has no grammars, and no <filled> action.

Form, Filled

Constructor Detail

Initial

public Initial()

Construct a new initial object without a node.

This is necessary for the node factory.

See Also:

VoiceXmlNodeFactory

Method Detail

getTagName

public java.lang.String getTagName()

Get the name of the tag for the derived node.

Returns:

name of the tag.

newInstance

public XmlNode newInstance(org.w3c.dom.Node n,
                           XmlNodeFactory<? extends XmlNode> factory)

Create a new instance for the given node.

Each XmlNode can serve as a prototype in a XmlNodeFactory to produce a collection of child nodes. Factories can then use the prototype pattern to produce new nodes.

Parameters:

n - The node to encapsulate.

factory - the factroy that calls this method.

Returns:

The new instance.

See Also:

XmlNodeFactory

getName

public java.lang.String getName()

Returns:

Value of the name attribute.

See Also:

ATTRIBUTE_NAME

setName

public void setName(java.lang.String name)

Set the name attribute.

Parameters:

name - Value of the name attribute.

See Also:

getExpr

public java.lang.String getExpr()

Retrieve the expr attribute.

Returns:

Value of the expr attribute.

See Also:

ATTRIBUTE_EXPR

setExpr

public void setExpr(java.lang.String expr)

Set the expr attribute.

Parameters:

expr - Value of the expr attribute.

See Also:

ATTRIBUTE_EXPR

getCond

public java.lang.String getCond()

Retrieve the cond attribute.

Returns:

Value of the cond attribute.

See Also:

ATTRIBUTE_COND

canContainChild

protected boolean canContainChild(java.lang.String tagName)

Can the specified sub-tag be contained within this node?

Specified by:

canContainChild in class AbstractXmlNode

Parameters:
