Methods

charAt(int position) → String
chunks() → Iterable<String>
concatImmutable(Rope other) → Rope: Creates a new Rope by concatenating another Rope (immutable)
copy() → Rope: Creates a deep copy of this Rope
delete(int start, int end) → void: Mutable delete - modifies this rope in place For immutable version, use deleteImmutable
deleteImmutable(int start, int end) → Rope: Creates a new Rope with text deleted between start and end (immutable)
findLineEnd(int offset) → int
findLineStart(int offset) → int
getBiDiSegmentsForLine(int lineIndex) → List<BiDiSegment>: Get BiDi segments for a specific line
getBiDiSegmentsInRange(int start, int end) → List<BiDiSegment>: Get BiDi segments within a character range
getLineAtOffset(int charOffset) → int
getLineStartOffset(int lineIndex) → int
getLineText(int lineIndex) → String
getRtlSegments() → List<(int, int)>: Get only RTL segments (useful for rendering)
getText() → String
insert(int position, String text) → void: Mutable insert - modifies this rope in place For immutable version, use insertImmutable
insertImmutable(int position, String text) → Rope: Creates a new Rope with text inserted at position (immutable)
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
splitImmutable(int position) → (Rope, Rope): Splits this rope at position, returning two new Ropes (immutable)
substring(int start, [int? end]) → String
toString() → String: A string representation of this object.
inherited
toStringWithBiDiControls() → String: Wrap text with appropriate BiDi control characters for rendering

Operators

operator ==(Object other) → bool: The equality operator.
