public final class Option
extends AbstractXmlNode

Specify an option in a <field>.

When a simple set of alternatives is all that is needed to specify the legal input values for a field, it may be more convenient to use an option list than a grammar. An option list is represented by a set of <option> elements contained in a <field> element. Each <option> element contains PCDATA that is used to generate a speech grammar.

Field Detail

TAG_NAME

public static final String TAG_NAME

Name of the tag.

Constant Field Values

ATTRIBUTE_DTMF

public static final String ATTRIBUTE_DTMF

An optional DTMF sequence for this option. It is equivalent to a simple DTMF <grammar> and DTMF properties apply to recognition of the sequence. Unlike DTMF grammars, whitespace is optional: dtmf="123#" is equivalent to dtmf="1 2 3 #". If unspecified, no DTMF sequence is associated with this option so it cannot be matched using DTMF.

See Also:

Constant Field Values

ATTRIBUTE_ACCEPT

public static final String ATTRIBUTE_ACCEPT

When set to "exact" (the default), the text of the option element defines the exact phrase to be recognized. When set to "approximate", the text of the option element defines an approximate recognition phrase.

See Also:

Constant Field Values

ATTRIBUTE_VALUE

public static final String ATTRIBUTE_VALUE

The string to assign to the field's form item variable when a user selects this option, whether by speech or DTMF. The default assignment is the CDATA content of the <option> element with leading and trailing white space removed. If this does not exist, then the DTMF sequence is used instead. If neither CDATA content nor a dtmf sequence is specified, then the default assignment is undefined and the field's form item variable is not filled.

Constant Field Values

ATTRIBUTE_NAMES

protected static final ArrayList<String> ATTRIBUTE_NAMES

Supported attribute names for this node.
