Detailed Description

Holds a set of named var objects.

This can be used as a basic structure to hold a set of var object, which can be retrieved by using their identifier.

Constructor & Destructor Documentation

NamedValueSet() [1/4]

NamedValueSet::NamedValueSet ( )

(

const NamedValueSet &

)

NamedValueSet() [3/4]

NamedValueSet::NamedValueSet ( NamedValueSet && )

noexcept

NamedValueSet() [4/4]

NamedValueSet::NamedValueSet

~NamedValueSet()

NamedValueSet::~NamedValueSet ( )

noexcept

Destructor.

Member Function Documentation

operator=() [1/2]

NamedValueSet & NamedValueSet::operator=

(

const NamedValueSet &

)

operator=() [2/2]

NamedValueSet & NamedValueSet::operator= ( NamedValueSet && )

noexcept

operator==()

bool NamedValueSet::operator== ( const NamedValueSet & ) const

noexcept

Two NamedValueSets are considered equal if they contain all the same key/value pairs, regardless of the order.

operator!=()

bool NamedValueSet::operator!= ( const NamedValueSet & ) const

noexcept

begin()

const NamedValueSet::NamedValue * NamedValueSet::begin ( ) const

noexcept

end()

const NamedValueSet::NamedValue * NamedValueSet::end ( ) const

noexcept

size()

int NamedValueSet::size ( ) const

noexcept

Returns the total number of values that the set contains.

isEmpty()

bool NamedValueSet::isEmpty ( ) const

noexcept

Returns true if the set is empty.

operator[]()

const var & NamedValueSet::operator[] ( const Identifier & name ) const

noexcept

Returns the value of a named item.

If the name isn't found, this will return a void variant.

getWithDefault()

var NamedValueSet::getWithDefault	(	const Identifier &	name,
		const var &	defaultReturnValue ) const

Tries to return the named value, but if no such value is found, this will instead return the supplied default value.

set() [1/2]

bool NamedValueSet::set	(	const Identifier &	name,
		const var &	newValue )

Changes or adds a named value.

Returns

true if a value was changed or added; false if the value was already set the value passed-in.

set() [2/2]

bool NamedValueSet::set	(	const Identifier &	name,
		var &&	newValue )

Changes or adds a named value.

Returns

true if a value was changed or added; false if the value was already set the value passed-in.

contains()

bool NamedValueSet::contains ( const Identifier & name ) const

noexcept

Returns true if the set contains an item with the specified name.

remove()

bool NamedValueSet::remove

(

const Identifier &

name

)

Removes a value from the set.

Returns

true if a value was removed; false if there was no value with the name that was given.

getName()

Identifier NamedValueSet::getName ( int index ) const

noexcept

Returns the name of the value at a given index.

The index must be between 0 and size() - 1.

getVarPointer() [1/2]

var * NamedValueSet::getVarPointer ( const Identifier & name )

noexcept

Returns a pointer to the var that holds a named value, or null if there is no value with this name.

Do not use this method unless you really need access to the internal var object for some reason - for normal reading and writing always prefer operator[]() and set(). Also note that the pointer returned may become invalid as soon as any subsequent methods are called on the NamedValueSet.

getVarPointer() [2/2]

const var * NamedValueSet::getVarPointer ( const Identifier & name ) const

noexcept

Returns a pointer to the var that holds a named value, or null if there is no value with this name.

Do not use this method unless you really need access to the internal var object for some reason - for normal reading and writing always prefer operator[]() and set(). Also note that the pointer returned may become invalid as soon as any subsequent methods are called on the NamedValueSet.

getValueAt()

const var & NamedValueSet::getValueAt ( int index ) const

noexcept

Returns the value of the item at a given index.

The index must be between 0 and size() - 1.

getVarPointerAt() [1/2]

var * NamedValueSet::getVarPointerAt ( int index )

noexcept

Returns the value of the item at a given index.

The index must be between 0 and size() - 1, or this will return a nullptr Also note that the pointer returned may become invalid as soon as any subsequent methods are called on the NamedValueSet.

getVarPointerAt() [2/2]

const var * NamedValueSet::getVarPointerAt ( int index ) const

noexcept

Returns the value of the item at a given index.

The index must be between 0 and size() - 1, or this will return a nullptr Also note that the pointer returned may become invalid as soon as any subsequent methods are called on the NamedValueSet.

indexOf()

int NamedValueSet::indexOf ( const Identifier & name ) const

noexcept

Returns the index of the given name, or -1 if it's not found.

clear()

void NamedValueSet::clear

(

)

Removes all values.

setFromXmlAttributes()

void NamedValueSet::setFromXmlAttributes

(

const XmlElement &

xml

)

Sets properties to the values of all of an XML element's attributes.

copyToXmlAttributes()

void NamedValueSet::copyToXmlAttributes

(

XmlElement &

xml

)

const

Sets attributes in an XML element corresponding to each of this object's properties.
