Constructor & Destructor Documentation

StringPairArray() [1/2]

juce::StringPairArray::StringPairArray

(

bool

ignoreCaseWhenComparingKeys = true

)

Creates an empty array

StringPairArray() [2/2]

juce::StringPairArray::StringPairArray

(

const StringPairArray &

other

)

Creates a copy of another array

~StringPairArray()

juce::StringPairArray::~StringPairArray ( )

default

Destructor.

Member Function Documentation

addArray()

void juce::StringPairArray::addArray

(

const StringPairArray &

other

)

Adds the items from another array to this one. This is equivalent to using set() to add each of the pairs from the other array.

addMap()

void juce::StringPairArray::addMap

(

const std::map< String, String > &

mapToAdd

)

Adds the contents of a map to this StringPairArray.

addMapImpl()

template<typename Map>

void juce::StringPairArray::addMapImpl ( const Map & mapToAdd )

private

addUnorderedMap()

void juce::StringPairArray::addUnorderedMap

(

const std::unordered_map< String, String > &

mapToAdd

)

Adds the contents of an unordered map to this StringPairArray.

clear()

void juce::StringPairArray::clear

(

)

Removes all elements from the array.

containsKey()

bool juce::StringPairArray::containsKey ( StringRef key ) const

noexcept

Returns true if the given key exists.

getAllKeys()

const StringArray & juce::StringPairArray::getAllKeys ( ) const

inlinenoexcept

Returns a list of all keys in the array.

getAllValues()

const StringArray & juce::StringPairArray::getAllValues ( ) const

inlinenoexcept

Returns a list of all values in the array.

getDescription()

String juce::StringPairArray::getDescription

(

)

const

Returns a descriptive string containing the items. This is handy for dumping the contents of an array.

getIgnoresCase()

bool juce::StringPairArray::getIgnoresCase ( ) const

noexcept

Indicates whether a case-insensitive search is used when looking up a key string.

getValue()

String juce::StringPairArray::getValue	(	StringRef	key,
		const String &	defaultReturnValue ) const

Finds the value corresponding to a key string. If no such key is found, this will just return the value provided as a default.

operator[]

minimiseStorageOverheads()

void juce::StringPairArray::minimiseStorageOverheads

(

)

Reduces the amount of storage being used by the array.

Arrays typically allocate slightly more storage than they need, and after removing elements, they may have quite a lot of unused space allocated. This method will reduce the amount of allocated storage to a minimum.

operator!=()

bool juce::StringPairArray::operator!=

(

const StringPairArray &

other

)

const

Compares two arrays. Comparisons are case-sensitive.

Returns

false if the other array contains exactly the same strings with the same keys

operator=()

StringPairArray & juce::StringPairArray::operator=

(

const StringPairArray &

other

)

Copies the contents of another string array into this one

operator==()

bool juce::StringPairArray::operator==

(

const StringPairArray &

other

)

const

Compares two arrays. Comparisons are case-sensitive.

Returns

true only if the other array contains exactly the same strings with the same keys

operator[]()

const String & juce::StringPairArray::operator[]

(

StringRef

key

)

const

Finds the value corresponding to a key string.

If no such key is found, this will just return an empty string. To check whether a given key actually exists (because it might actually be paired with an empty string), use the getAllKeys() method to obtain a list.

Obviously the reference returned shouldn't be stored for later use, as the string it refers to may disappear when the array changes.

getValue

remove() [1/2]

void juce::StringPairArray::remove

(

int

index

)

Removes a string from the array based on its index. If the index is out-of-range, no action will be taken.

remove() [2/2]

void juce::StringPairArray::remove

(

StringRef

key

)

Removes a string from the array based on its key. If the key isn't found, nothing will happen.

set()

void juce::StringPairArray::set	(	const String &	key,
		const String &	value )

Adds or amends a key/value pair. If a value already exists with this key, its value will be overwritten, otherwise the key/value pair will be added to the array.

setIgnoresCase()

void juce::StringPairArray::setIgnoresCase

(

bool

shouldIgnoreCase

)

Indicates whether to use a case-insensitive search when looking up a key string.

size()

int juce::StringPairArray::size ( ) const

inlinenoexcept

Returns the number of strings in the array
