Member Function Documentation

◆ Next()

size_t OSXStringIterator::Next ( IterType  what)
overridevirtual

Advance the cursor by one iteration unit.

Returns
New cursor position (in bytes) or END if the cursor is already at the end of the string.

Implements StringIterator.

Definition at line 448 of file string_osx.cpp.

References StringIterator::ITER_CHARACTER, and StringIterator::ITER_WORD.

◆ Prev()

size_t OSXStringIterator::Prev ( IterType  what)
overridevirtual

Move the cursor back by one iteration unit.

Returns
New cursor position (in bytes) or END if the cursor is already at the start of the string.

Implements StringIterator.

Definition at line 462 of file string_osx.cpp.

References StringIterator::ITER_CHARACTER, and StringIterator::ITER_WORD.

◆ SetCurPosition()

size_t OSXStringIterator::SetCurPosition ( size_t  pos)
overridevirtual

Change the current string cursor.

Parameters
posNew cursor position.
Returns
Actual new cursor position at the next valid character boundary.
Precondition
pos has to be inside the current string.

Implements StringIterator.

Definition at line 430 of file string_osx.cpp.

◆ SetString()

void OSXStringIterator::SetString ( const char *  s)
overridevirtual

Set a new iteration string.

Must also be called if the string contents changed. The cursor is reset to the start of the string.

Parameters
sNew string.

< UTF-16 copy of the string.

Implements StringIterator.
