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::NamedValueSet

(

)

Creates an empty set.

NamedValueSet::NamedValueSet

(

const NamedValueSet &

other

)

Creates a copy of another set.

NamedValueSet::~NamedValueSet

(

)

Destructor.

Member Function Documentation

NamedValueSet& NamedValueSet::operator=

(

const NamedValueSet &

other

)

Replaces this set with a copy of another set.

bool NamedValueSet::operator==

(

const NamedValueSet &

other

)

const

bool NamedValueSet::operator!=

(

const NamedValueSet &

other

)

const

int NamedValueSet::size

(

)

const

Returns the total number of values that the set contains.

const var& NamedValueSet::operator[]

(

const Identifier &

name

)

const

Returns the value of a named item.

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

getProperty

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.

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 the value passed-in.

bool NamedValueSet::contains

(

const Identifier &

name

)

const

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

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.

const Identifier NamedValueSet::getName

(

int

index

)

const

Returns the name of the value at a given index.

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

const var& NamedValueSet::getValueAt

(

int

index

)

const

Returns the value of the item at a given index.

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

void NamedValueSet::clear

(

)

Removes all values.

var* NamedValueSet::getVarPointer

(

const Identifier &

name

)

const

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().

void NamedValueSet::setFromXmlAttributes

(

const XmlElement &

xml

)

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

void NamedValueSet::copyToXmlAttributes

(

XmlElement &

xml

)

const

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