For delete operations, the InsertionLength is 0. For insert operations that have no selection of text to be replaced, the DeletionLength is 0.

Properties

DeletionEndOffset

The offset at which the deletion ended.

int DeletionEndOffset { get; }

int

DeletionEndPosition

bool:

true if any text was deleted; otherwise, false.

HasInsertion

Indicates whether the operation inserted any text.

bool HasInsertion { get; }

Property Value

IsIgnoredForTranslation

Indicates whether the operation is a simple replace such as a character casing update that should be ignored for translation.

bool IsIgnoredForTranslation { get; }

Property Value

bool:

true if the operation is a simple replace such as a character casing update that should be ignored for translation; otherwise, false.

LengthDelta

The net change in length to the document after performing the operation.

int LengthDelta { get; }

int

Remarks

This value is the InsertionLength minus the DeletionLength.

LinesDeleted

The number of document lines deleted after performing the operation.

int LinesDeleted { get; }

Property Value
