Field Detail

TAG_NAME

public static final java.lang.String TAG_NAME

Name of the tag.

See Also:

Constant Field Values

ATTRIBUTE_REPEAT

public static final java.lang.String ATTRIBUTE_REPEAT

Defines a legal rule expansion as being another sub-expansion that is optional, that is repeated zero or more times, that is repeated one or more times, or that is repeated some range of times.

See Also:

Constant Field Values

ATTRIBUTE_REPEAT_PROB

public static final java.lang.String ATTRIBUTE_REPEAT_PROB

Any repeat operator may specify an optional repeat probability. The value indicates the probability of successive repetition of the repeated expansion.

See Also:

Constant Field Values

ATTRIBUTE_WEIGHT

public static final java.lang.String ATTRIBUTE_WEIGHT

A weight may be optionally provided for any number of alternatives in an alternative expansion. Weights are simple positive floating point values without exponentials. Legal formats are "n", "n.", ".n" and "n.n" where "n" is a sequence of one or many digits. A weight is nominally a multiplying factor in the likelihood domain of a speech recognition search. A weight of 1.0 is equivalent to providing no weight at all. A weight greater than "1.0" positively biases the alternative and a weight less than "1.0" negatively biases the alternative.

See Also:

Constant Field Values

ATTRIBUTE_XML_LANG

public static final java.lang.String ATTRIBUTE_XML_LANG

The language identifier for the grammar. If omitted, the value is inherited down from the document hierarchy.

See Also:

Constant Field Values

ATTRIBUTE_NAMES

protected static final java.util.ArrayList<java.lang.String> ATTRIBUTE_NAMES

Supported attribute names for this node.

Constructor Detail

Item

public Item()

Construct a new item object without a node.

This is necessary for the node factory.

See Also:

SrgsNodeFactory

Method Detail

getTagName

public java.lang.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(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.

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
