Detailed Description

A DbProfile is a container for access parameters to a database.

This class provides a utility for (keyword) parameter management to access a database system. Profiles can be used to specify all parameters necessary to apply to programatic interfaces to database software such as Qt's SQL Module class, QSqlDatabase.

Using QSqlDatabase as an example, keywords such as User, Host, Port, and Dbname can be stored in this object and retrieved easily.

It can be easily adapted to any database software API by externally managing the contents of a configuration file. See DbAccess for additional details on how this scheme can be utilized.

◆ DbProfile() [3/4]

Isis::DbProfile::DbProfile	(	const DbProfile &	prof1,
		const DbProfile &	prof2,
		const QString &	name = `""`
	)

Creates a profile from the merging of two a DbProfiles.

This constructor will create a new DbProfile from two existing DbProfiles. Its intended use is for the merging of keys in an ordered fashion. It is useful when a higher level class inherits this class and a specific implementations calls for the keys to come from both the parent and the child DbProfile.

It should be noted that this is a convenient way to merge high level database access parameters with individual profile access where the last keys take precedence over the first. Thus, in the case where the same keys exist in both the first and second profiles, keys in the second profile take precedence. This is great for defining general database parameters in the top level database configure section and having individual profiles redefine certain access parameters.

Parameters

name	Name of new profile
prof1	First profile to merge
prof2	Second profile to merge

◆ DbProfile() [4/4]

Isis::DbProfile::DbProfile ( PvlContainer & pvl )

Creates a DbProfile from a Pvl entity.

This constructor will create a DbProfile by reading keywords from a Pvl container. Pvl Containers can be an Object or a Group, or simply a list of keywords. This PvlContainer is expected to point to the appropriate keywords that the caller has pre-established by normal Isis Pvl methods.

Parameters

pvl	Pvl container of keywords to make a DbProfile from

Member Function Documentation

◆ add()

void Isis::DbProfile::add	(	const QString &	key,
		const QString &	value = `""`
	)

Adds a keyword and value pair to the profile.

This method adds a keyword and value pair to the profile if it doesn't exist. If the keyword already exists,it appends the value to the existing keyword.

Parameters

key	Keyword to add or ammend
value	Value to add to the keyword

References Isis::CollectorMap< K, T, ComparePolicy, RemovalPolicy, CopyPolicy >::add(), Isis::PvlKeyword::addValue(), Isis::CollectorMap< K, T, ComparePolicy, RemovalPolicy, CopyPolicy >::exists(), Isis::CollectorMap< K, T, ComparePolicy, RemovalPolicy, CopyPolicy >::get(), key(), and value().

◆ count()

int Isis::DbProfile::count ( const QString & key ) const

Report number of values in keyword.

This method will return the number of values in the specified keyword. If the keyword does not exist, 0 is returned.

Parameters

key	Name of key to get value count for

Returns: int Number values in key, or 0 if the key does not exist

References Isis::CollectorMap< K, T, ComparePolicy, RemovalPolicy, CopyPolicy >::exists(), Isis::CollectorMap< K, T, ComparePolicy, RemovalPolicy, CopyPolicy >::get(), key(), and Isis::PvlKeyword::size().

Referenced by Isis::PhotometricFunction::ConfKey(), and Isis::ConfKey().

◆ exists()

bool Isis::DbProfile::exists ( const QString & key ) const

inline

Checks for the existance of a keyword.

Parameters

key	Name of keyword to check

Returns: bool True if it exists, false if it doesn't

References Isis::CollectorMap< K, T, ComparePolicy, RemovalPolicy, CopyPolicy >::exists(), and key().

◆ getKeyList()

const KeyList& Isis::DbProfile::getKeyList ( ) const

inlineprotected

Returns a reference to the key list.

Direct access to the keyword container allows class developers some additional flexibility whilst maintaining integrity through the public interface.

Returns: const KeyList& Reference to keyword list

◆ isValid()

bool Isis::DbProfile::isValid ( ) const

inline

Reports if this is a valid profile.

A valid profile is simply defined to contain keys. If there are no keys defined for the profile, it is deemed invalid.

Returns: bool True if the profile is valid, therefore containing keys

References size().

Referenced by Isis::Database::init().

◆ key()

QString Isis::DbProfile::key ( int nth ) const

inline

Returns the nth key in the profile.

This method returns the name of the nth keyword in the profile so one can iterate through all existing keys. Note that database passwords could be vulnerable to exposure via this method.

Keywords in the profile are sorted in alphabetical order and not in the order in which they are read.

Parameters

nth	Specifies the nth key in the profile

Returns: QString Name of nth keyword in the profile.

Exceptions

Out-of-range exception if the nth keyword does not exist

◆ loadkeys()

void Isis::DbProfile::loadkeys ( PvlContainer & pvl )

protected

Loads DbProfile keys from the given Pvl construct.

This method iterates through all keywords in the Pvl container and loads them into this property.

Parameters

pvl	Container of keywords that will be loaded

◆ Name()

QString Isis::DbProfile::Name ( ) const

inline

Returns the name of this property.

QString Isis::DbProfile::operator()	(	const QString &	key,
		int	nth = `0`
	)		const

Returns the specified value for the given keyword.

This method returns a value from the specified keyword. If the keyword or the specified value does not exist, an exception is thrown.

Parameters

key	Name of keyword to return value for.
nth	Specifies the nth value in the keyword

Returns: QString The requested value in the keyword

◆ remove()

void Isis::DbProfile::remove ( const QString & key )

Removes a keyword from the profile.

Parameters

◆ replace()

void Isis::DbProfile::replace	(	const QString &	key,
		const QString &	value = `""`
	)

Adds a keyword and value pair to the profile.

This method adds a keyword and value pair to the profile if it doesn't exist.

If the keyword already exists, it is deleted and replaced with this new keyword and value.

Parameters

key	Keyword to replace
