Detailed Description

Represents a string identifier, designed for accessing properties by name.

Comparing two Identifier objects is very fast (an O(1) operation), but creating them can be slower than just using a String directly, so the optimal way to use them is to keep some static Identifier objects for the things you use often.

Constructor & Destructor Documentation

◆ Identifier() [1/3]

juce::Identifier::Identifier ( const char *  name)

Creates an identifier with a specified name.

Because this name may need to be used in contexts such as script variables or XML tags, it must only contain ascii letters and digits, or the underscore character.

Definition at line 52 of file juce_Identifier.cpp.

◆ Identifier() [2/3]

juce::Identifier::Identifier ( const String name)

Creates an identifier with a specified name.

Because this name may need to be used in contexts such as script variables or XML tags, it must only contain ascii letters and digits, or the underscore character.

Definition at line 45 of file juce_Identifier.cpp.

References juce::String::isNotEmpty().

◆ Identifier() [3/3]

juce::Identifier::Identifier ( String::CharPointerType  nameStart,
String::CharPointerType  nameEnd 
)

Creates an identifier with a specified name.

Because this name may need to be used in contexts such as script variables or XML tags, it must only contain ascii letters and digits, or the underscore character.

Definition at line 59 of file juce_Identifier.cpp.

Member Function Documentation

◆ operator==()

bool juce::Identifier::operator== ( const Identifier other) const
inlinenoexcept

Compares two identifiers.

This is a very fast operation.

Definition at line 82 of file juce_Identifier.h.

References juce::String::getCharPointer().

◆ operator!=()

bool juce::Identifier::operator!= ( const Identifier other) const
inlinenoexcept

Compares two identifiers.

This is a very fast operation.

Definition at line 85 of file juce_Identifier.h.

References juce::String::getCharPointer().

◆ isValidIdentifier()

bool juce::Identifier::isValidIdentifier ( const String possibleIdentifier)
staticnoexcept

Checks a given string for characters that might not be valid in an Identifier.

Since Identifiers are used as a script variables and XML attributes, they should only contain alphanumeric characters, underscores, or the '-' and ':' characters.
