Field Detail

TAG_NAME

public static final String TAG_NAME

Name of the tag.

See Also:

Constant Field Values

ATTRIBUTE_REPEAT

public static final 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 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 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 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 ArrayList<String> ATTRIBUTE_NAMES

Supported attribute names for this node.
