Detailed Description

String class to replace QString (work in progress).

Beside the usual string functions, a UString can be constructed from an atom. This makes the strings very small, since only the atom index is stored, and fast for comparisons and copies.

Member Function Documentation

◆ c_str()

const char * UString::c_str ( ) const

Returns the zero terminated C-String.

This is always safe to use also for empty strings.

◆ fromAtom() [1/2]

UString UString::fromAtom ( AT_Atom  atom)
static

Constructs a UString from an atom.

No dynamic heap allocations are done as only the index referencing the atom is stored.

◆ fromAtom() [2/2]

UString UString::fromAtom ( AT_AtomIndex  ati)
static

Constructs a UString from an atom index.

No dynamic heap allocations are done as only the index referencing the atom is stored.

◆ size()

unsigned UString::size ( ) const

Returns the byte size of the string.

Note for multibyte UTF-8 characters the size is larger than the codepoint count.
