ULDissector Class Reference

A ULDissector is a worker that performs morphological analysis of words in a particular language. Each ULDissector contains a pointer to a language data source and a dictionary data source. The language data source provides information about the general morphological structure of the language in question, while the dictionary data source provides a list of words in the language along with their parts of speech.

Detailed Description

A ULDissector is a worker that performs morphological analysis of words in a particular language. Each ULDissector contains a pointer to a language data source and a dictionary data source. The language data source provides information about the general morphological structure of the language in question, while the dictionary data source provides a list of words in the language along with their parts of speech.

Constructor & Destructor Documentation

ULDissector::ULDissector

(

)

Default constructor.

ULDissector::ULDissector

(

const ULDissector &

other

)

Copy constructor.

ULDissector::~ULDissector ( )

virtual

Destructor.

Member Function Documentation

void ULDissector::clear

(

)

Sets this dissector to its default state.

ULError ULDissector::dissect	(	const ULString &	surfaceForm,
		ULList< ULDerivation > &	dissectionList
	)

Performs a morphological analysis of the specified surface form.

Returns

ULError::NoError or ULError::ObjectUninitialized (if one or both of the required data sources is undefined),

Parameters

[in]	surfaceForm	The word to be analyzed.
[out]	dissectionList	The list of separate analyses of the surface form. For example, if surfaceForm is "rakes" and the language is English, then dissectionList will include one ULDerivation representing the plural of the noun "rake", and another ULDerivation representing the third person singular present tense of the verb "to rake".

ULError ULDissector::dissect	(	const ULString &	surfaceForm,
		const ULPartOfSpeechCategory &	category,
		ULList< ULDerivation > &	dissectionList
	)

ULError ULDissector::dissect	(	const ULString &	surfaceForm,
		uluint32	maxDerivationLength,
		ULList< ULDerivation > &	derivationList
	)

Performs a morphological analysis of the specified surface form.

Returns

ULError::NoError or ULError::ObjectUninitialized (if one or both of the required data sources is undefined),

Parameters

[in]	surfaceForm	The word to be analyzed.
[in]	maxDerivationLength	the longest rule sequence we're willing to allow in a derivation.
[out]	derivationList	The list of separate analyses of the surface form. For example, if surfaceForm is "rakes" and the language is English, then derivationList will include one ULDerivation representing the plural of the noun "rake", and another ULDerivation representing the third person singular present tense of the verb "to rake".

ULError ULDissector::dissect	(	const ULString &	surfaceForm,
		const ULPartOfSpeechCategory &	category,
		uluint32	maxDerivationLength,
		ULList< ULDerivation > &	derivationList
	)

Performs a morphological analysis of the specified surface form under the assumption that the surface form has the specified part of speech.

Returns

ULError::NoError or ULError::ObjectUninitialized (if one or both of the required data sources is undefined),

Parameters

[in]	surfaceForm	The word to be analyzed.
[in]	category	The word to be analyzed.
[in]	maxDerivationLength	the longest rule sequence we're willing to allow in a derivation.
[out]	derivationList	The list of separate analyses of the surface form.

void ULDissector::getAvailableServices ( ULList< ULServiceDescriptor > &  serviceList )

virtual

Parameters

[out]

serviceList

Used to return a list of all the services this ULWorker can provide.

Implements ULWorker.

ULDictionaryDataSource * ULDissector::getDictionaryDataSource

(

)

Returns

a pointer to the dictionary data source used by this dissector.

ULInflector * ULDissector::getInflector

(

)

Returns

a pointer to the inflector used by this dissector.

const ULLanguage & ULDissector::getLanguage

(

)

const

Returns

the language for which this dissector performs morphological analysis.

ULLanguageDataSource * ULDissector::getLanguageDataSource

(

)

Returns

a pointer to the language data source used by this dissector.

bool ULDissector::isServiceAvailable ( const ULServiceDescriptor &  service )

virtual

Returns

true if the specified service can be performed by this ULWorker, and false otherwise.

Parameters

service

The desired service.

Implements ULWorker.

ULDissector & ULDissector::operator=

(

const ULDissector &

other

)

Assignment operator.

void ULDissector::setDictionaryDataSource

(

ULDictionaryDataSource *

dataSource

)

Assigns the dictionary data source to be used by this dissector. The ULDissector does not take responsibility for deleting the data source. That will need to happen elsewhere (typically the ULFactory will take care of it if your application uses ULFactory to instantiate data sources and workers).

Parameters

[in]

dataSource

A pointer to the desired dictionary data source.

void ULDissector::setInflector

(

ULInflector *

newInflector

)

Assigns the inflector to be used by this dissector. The ULDissector does not take responsibility for deleting the inflector. That will need to happen elsewhere (typically the ULFactory will take care of it if your application uses ULFactory to instantiate data sources and workers).

Parameters

[in]

newInflector

A pointer to the desired inflector.

void ULDissector::setLanguageDataSource

(

ULLanguageDataSource *

dataSource

)

Assigns the language data source to be used by this dissector. The ULDissector does not take responsibility for deleting the data source. That will need to happen elsewhere (typically the ULFactory will take care of it if your application uses ULFactory to instantiate data sources and workers).

Parameters

[in]

dataSource

A pointer to the desired language data source.
