Constructor Detail

XML2UttBase

public XML2UttBase(java.lang.String name,
                   MaryDataType input,
                   MaryDataType output)

Method Detail

startup

public void startup()
             throws java.lang.Exception

Description copied from interface: MaryModule

Allow the module to start up, performing whatever is necessary to become operational. After successful completion, getState() should return MODULE_RUNNING.

Specified by:

startup in interface MaryModule

Overrides:

startup in class InternalModule

Throws:

java.lang.Exception

process

public MaryData process(MaryData d)
                 throws java.lang.Exception

Description copied from class: InternalModule

Perform this module's processing on abstract "MaryData" input d. Subclasses need to make sure that the process() method is thread-safe, because in server-mode, it will be called from different threads at the same time. A sensible way to do this seems to be not to use any global or static variables, or to use them read-only.

Specified by:

process in interface MaryModule

Overrides:

process in class InternalModule

Returns:

A MaryData object of type outputType() encapsulating the processing result.

This method just returns its input. Subclasses should override this.

Throws:

java.lang.Exception

fillUtterance

protected abstract void fillUtterance(com.sun.speech.freetts.Utterance utterance,
                                      org.w3c.dom.Element sentence)

Depending on the data type, find the right information in the sentence and insert it into the utterance.

fillUtterance

protected void fillUtterance(com.sun.speech.freetts.Utterance utterance,
                             org.w3c.dom.Element sentence,
                             boolean createWordRelation,
                             boolean createSylStructRelation,
                             boolean createTargetRelation)

Depending on the data type, find the right information in the sentence and insert it into the utterance.

addOneElement

protected java.lang.String addOneElement(com.sun.speech.freetts.Utterance utterance,
                                         org.w3c.dom.Element element,
                                         boolean createWordRelation,
                                         boolean createSylStructRelation,
                                         boolean createTargetRelation)

To a given utterance in which relations have already been created appropriately, add a single boundary, t or mtu element.

Parameters:

utterance -

element -

createWordRelation -

createSylStructRelation -

createTargetRelation -

Returns:

a string containing the text in this element, or an empty string

appendTokenItem

protected com.sun.speech.freetts.Item appendTokenItem(com.sun.speech.freetts.Relation tokenRelation,
                                                      java.lang.String tokenText)

Append one item to the token relation, and return it. If tokenText is null, a "placeholder" token item will be created, in which no "name" feature is present, but to which other features can already be added. If the tail of tokenRelation is such a placeholder token, the tokenText will be set as that placeholder's name feature, and the ex-placeholder item will be returned. If the tail of tokenRelation is a placeholder and tokenText is null, no new placeholder will be created, i.e. it is not possible to create two subsequent placeholder items.

Parameters:

tokenRelation -

tokenText -

Returns:

the new item

insertWordItem

protected com.sun.speech.freetts.Item insertWordItem(com.sun.speech.freetts.Relation wordRelation,
