IsReadOnly(Span)
Determines whether a text modification or deletion would be prohibited at span due to an IReadOnlyRegion

- span
- Span
The span to check.
Returns
true if the entire span could be deleted or replaced, otherwise false.
Exceptions
span is null.
The End property of span is greater than CurrentSnapshot.Length.
TakeThreadOwnership() has previously been called, and this call is being made from a different thread.
Applies to
IsReadOnly(Int32)
Determines whether a text insertion would be prohibited at position due to an IReadOnlyRegion.

- position
- Int32
The position of the proposed text insertion.
Returns
true if an IReadOnlyRegion would prohibit insertions at this position, otherwise false.
Exceptions
position is negative or greater than CurrentSnapshot.Length.
TakeThreadOwnership() has previously been called, and this call is being made from a different thread.
Applies to
IsReadOnly(Span, Boolean)

- span
- Span
The span to check.
- isEdit
- Boolean
true if this check is part of an edit. false for a query without side effects.
Returns
true if the entire span could be deleted or replaced, false otherwise.
Exceptions
span is null.
The End property of span is greater than CurrentSnapshot.Length.
