Detailed Description

Feature nomenclature database querier.

This class queries the nomenclature database for features. To use this class, you create a blank instance. Then you connect to the featuresIdentified() signal. Finally, you call query with the appropriate input data. You can call query as many times as you want; featuresIdentified() will be emitted the same number of times. Finally, you can access the features with features().

Member Enumeration Documentation

IAUStatus

enum Isis::FeatureNomenclature::IAUStatus

Enumeration of approval statuses.

Enumerator
NoStatus	When this status is assigned to a feature, there will be no status displayed and the feature will not be shown if the IAU approved only checkbox is checked.
Approved	When this status is assigned to a feature, the displayed status will be "Adopted by the IAU" and the feature will always be shown.
Dropped	When this status is assigned to a feature, the displayed status will be "Dropped, disallowed" and the feature will not be shown if the IAU approved only checkbox is checked.
Unapproved	When this status is assigned to a feature, the displayed status will be "Never approved by the IAU" and the feature will not be shown if the IAU approved only checkbox checked.

Constructor & Destructor Documentation

FeatureNomenclature() [1/2]

Isis::FeatureNomenclature::FeatureNomenclature

(

)

Instantiate a feature nomenclature.

This prepares to make network requests.

FeatureNomenclature() [2/2]

Isis::FeatureNomenclature::FeatureNomenclature

(

const FeatureNomenclature &

other

)

Copy a feature nomenclature.

Data being queried currently will not be available in the copy, but ready results will be available.

Parameters

other

The feature nomenclature to copy

~FeatureNomenclature()

Isis::FeatureNomenclature::~FeatureNomenclature

(

)

Frees allocated memory.

Member Function Documentation

featureDiameterGreaterThan()

bool Isis::FeatureNomenclature::featureDiameterGreaterThan ( const FeatureNomenclature::Feature & lhs, const FeatureNomenclature::Feature & rhs )

static

Compare the diameter of two features.

This is very useful for sorting with qSort(). If lhs > rhs, then this returns true. This considers valid data

‍invalid data.

Parameters

lhs	The left hand side of the '>' operator
rhs	The right hand side of the '>' operator

Returns

lhs > rhs

features()

QList< FeatureNomenclature::Feature > Isis::FeatureNomenclature::features

(

)

const

This gives you the features found in all of the queries so far.

If all of the queries are finished, then this list will contain all of the results. The list will be empty if no queries have succeeded so far.

Returns

a cumulative list of all of the features found so far.

featuresIdentified

void Isis::FeatureNomenclature::featuresIdentified ( FeatureNomenclature * )

signal

This is emitted when a query is completed.

When emitted, the this pointer is provided.

hasResult()

bool Isis::FeatureNomenclature::hasResult

(

)

const

Test if any understandable results have been received from the nomenclature database.

Returns

True if any queries have succeeded.

operator=()

FeatureNomenclature & Isis::FeatureNomenclature::operator=

(

const FeatureNomenclature &

rhs

)

This takes on the data from rhs.

Active queries will not be copied. This is exception safe.

Parameters

rhs	The FeatureNomenclature on the right hand side of the '='

Returns

*this

References swap().

queryFeatures()

void Isis::FeatureNomenclature::queryFeatures	(	QString	target,
		Latitude	startLat,
		Longitude	startLon,
		Latitude	endLat,
		Longitude	endLon )

Makes sure the longitudinal ranges are correct.

If the range intersects with the 0 line the range is split into two ranges, the minimum to 360 and 0 to the maximum. Then it runs a query on each range.

Parameters

target	The target for which features might be present
startLat	The minimum latitude of the ground range to search
startLon	The minimum longitude of the ground range to search
endLat	The maximum latitude of the ground range to search
endLon	The maximum longitude of the ground range to search

References Isis::Longitude::to360Range().

swap()

void Isis::FeatureNomenclature::swap

(

FeatureNomenclature &

other

)

Swap the instances *this and other.

This cannot throw an exception.

Parameters

other

The FeatureNomenclature to trade data with.
