Class Rule

java.lang.Object
  org.jvoicexml.xml.AbstractXmlNode
      org.jvoicexml.xml.srgs.Rule

All Implemented Interfaces:

SrgsNode, VoiceXmlNode, XmlNode, Node

public final class Rule
extends AbstractXmlNode
implements VoiceXmlNode

A rule definition associates a legal rule expansion with a rulename. The rule definition is also responsible for defining the scope of the rule definition: whether it is local to the grammar in which it is defined or whether it may be referenced within other grammars. Finally, the rule definition may additionally include documentation comments and other pragmatics.

The rulename for each rule definition must be unique within a grammar. The same rulename may be used in multiple grammars.

Constructor Detail

Rule

public Rule()

Construct a new rule object without a node.

This is necessary for the node factory.

See Also:

VoiceXmlNodeFactory

Method Detail

getTagName

public String getTagName()

Get the name of the tag for the derived node.

Specified by:

getTagName in interface XmlNode

Returns:

name of the tag.

newInstance

public XmlNode newInstance(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.

Specified by:

newInstance in interface XmlNode

Parameters:

n - The node to encapsulate.

factory - the factroy that calls this method.

Returns:

The new instance.

See Also:

XmlNodeFactory

getId

public String getId()

Retrieve the id attribute.

Returns:

Value of the id attribute.

See Also:

ATTRIBUTE_ID

setId

public void setId(String id)

Set the id attribute.

Parameters:

id - Value of the id attribute.

See Also:

ATTRIBUTE_ID

getScope

public String getScope()

Retrieve the scope attribute.

Returns:

Value of the scope attribute.

See Also:

ATTRIBUTE_SCOPE

setScope

public void setScope(String scope)

Set the scope attribute.

Parameters:

scope - Value of the scope attribute.

See Also:

ATTRIBUTE_SCOPE

makePrivate

public void makePrivate()

. Marks this rule as private

Since:

0.7.4

makePublic

public void makePublic()

Marks this rule as public.

Since:

0.7.4

isPublic

public boolean isPublic()

Create a new text within this node.

Parameters:

text - The text to be added.

Returns:

The new created text.

canContainChild

protected boolean canContainChild(String tagName)

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

Specified by:

canContainChild in class AbstractXmlNode

Parameters:

tagName - Name of child.

Returns:

True if the sub-tag is allowed on this node.

getAttributeNames

public Collection<String> getAttributeNames()

Returns a collection of permitted attribute names for the node.

Specified by:

getAttributeNames in interface XmlNode

Overrides:
