Member Function Documentation

◆ checkContainsOnly()

cres_qresult< void > ValueHash::checkContainsOnly ( const Uri & _uri ) const

Check that the list only contains value of type _uri. It returns success if that is true. It returns a failure with an error message in case a value has a different type in the list.

◆ clear()

void ValueHash::clear ( )

Clear the hash.

◆ contains() [1/3]

bool ValueHash::contains ( const QString & _key ) const

Returns: if the value is contained in the hash.

◆ contains() [2/3]

template<typename _T_ >

bool knowCore::ValueHash::contains ( const QString & _key ) const

Returns: if the value is contained in the hash and is of type _T_.

◆ contains() [3/3]

bool ValueHash::contains	(	const QString &	_key,
		const knowCore::Uri &	_datatype ) const

Returns: if the value is contained in the hash and has the given _datatype.

◆ ensureContains() [1/2]

template<typename _T_ >

cres_qresult< void > knowCore::ValueHash::ensureContains ( const QString & _key ) const

Returns: if the value is contained in the hash and is of type _T_.

◆ ensureContains() [2/2]

cres_qresult< void > ValueHash::ensureContains	(	const QString &	_key,
		const knowCore::Uri &	_datatype ) const

Returns: if the value is contained in the hash and has the given _datatype.

◆ hash() [1/2]

template<typename _T_ >

cres_qresult< QHash< QString, _T_ > > knowCore::ValueHash::hash ( ) const

inline

Returns

attempt to return as a hash of a specific type

T if they are convertible to
T

◆ hash() [2/2]

QHash< QString, Value > ValueHash::hash ( ) const

Returns: the underlying QHash<QString, Value>

◆ insert() [1/8]

ValueHash & ValueHash::insert ( const knowCore::ValueHash & _value )

Merge a QVariantHash into the hash.

◆ insert() [2/8]

cres_qresult< void > ValueHash::insert ( const QJsonObject & _value )

Attempt to insert the content of a QJsonObject to the hash.

◆ insert() [3/8]

template<typename _T_ >

ValueHash & knowCore::ValueHash::insert	(	const QString &	_key,
		const _T_ &	_value )

inline

Add a value to the hash with the given key.

◆ insert() [4/8]

template<typename _T_ , typename... _TOther_>

ValueHash & knowCore::ValueHash::insert	(	const QString &	_key,
		const _T_ &	_value,
		const QString &	_key_n,
		const _TOther_ &...	_other )

inline

Add a set of keys/values to the hash.

◆ insert() [5/8]

ValueHash & ValueHash::insert	(	const QString &	_key,
		const knowCore::Value &	_value )

Add a value to the hash with the given key.

◆ insert() [6/8]

cres_qresult< void > ValueHash::insert	(	const QString &	_key,
		const QVariant &	_value )

Add a value from variant. This can potentially trigger a failure that is detected at create.

◆ insert() [7/8]

cres_qresult< void > ValueHash::insert ( const QVariantHash & _value )

Merge a QVariantHash into the hash.

◆ insert() [8/8]

cres_qresult< void > ValueHash::insert ( const QVariantMap & _value )

Merge a QVariantMap into the hash.

◆ keys()

QStringList ValueHash::keys ( ) const

Returns: the list of keys

◆ map() [1/2]

template<typename _T_ >

cres_qresult< QMap< QString, _T_ > > knowCore::ValueHash::map ( ) const

inline

Returns

attempt to return as a map of a specific type

T if they are convertible to
T

◆ map() [2/2]

QMap< QString, Value > knowCore::ValueHash::map ( ) const

inline

Returns: convert the underlying hash into a QMap<QString, Value>

◆ operator Value()

knowCore::ValueHash::operator Value ( ) const

inline

Allow direct casting to Value.

◆ remove()

ValueHash & ValueHash::remove ( const QString & _key )

Remove the _key.

◆ size()

int ValueHash::size ( ) const

Returns: the number of elements in the hash

◆ toVariantHash()

QVariantHash ValueHash::toVariantHash ( ) const

Returns: a variant hash representation

◆ toVariantMap()

QVariantMap ValueHash::toVariantMap ( ) const

Returns: a variant map representation

◆ value() [1/3]

Value ValueHash::value ( const QString & _key ) const

Returns

the value for the given

_key or an empty value

◆ value() [2/3]

template<typename _T_ >

cres_qresult< _T_ > knowCore::ValueHash::value ( const QString & _key ) const

inline

Returns

attempt to return the value for the given

_key if convertible to
T

◆ value() [3/3]

template<typename _T_ >

cres_qresult< _T_ > knowCore::ValueHash::value	(	const QString &	_key,
		const _T_ &	_default ) const

inline

Returns

attempt to return the value for the given

_key if convertible to
T
