TextLineChange Structure
Provides settings for tracking changes to any text line in the buffer.
Assembly: Microsoft.VisualStudio.TextManager.Interop (in Microsoft.VisualStudio.TextManager.Interop.dll)
The TextLineChange type exposes the following members.
| Name | Description | |
|---|---|---|
 | Equals | Indicates whether this instance and a specified object are equal. (Inherited from ValueType.) |
| GetHashCode | Returns the hash code for this instance. (Inherited from ValueType.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToString | Returns the fully qualified type name of this instance. (Inherited from ValueType.) |
| Name | Description | |
|---|---|---|
| iNewEndIndex | Endpoint of the inserted text. |
| iNewEndLine | End line of the inserted text. |
| iOldEndIndex | End point of the deleted text. |
| iOldEndLine | End line of deleted text. |
| iStartIndex | Start point of the old and new text. |
| iStartLine | Start line of the old and new text. |
The TextLineChange structure completely describes a text change. For example, for a Replace operation, the structure defines two spans, as follows:
From iStartLine/iStartIndex to iNewEndLine/iNewEndIndex. This span indicates the extent of the newly inserted text in terms of the buffer's current state.
From iStartLine/iStartIndex to iOldEndLine/iOldEndIndex. This span describes the extent of the text that was deleted, in terms of the buffer's state before the change.
Therefore, the structure contains information about the shape of the region before and after the change. The TextLineChange structure does not contain the old text that was deleted.
