Public Structure TextLineChange
public struct TextLineChange
public value class TextLineChange

type TextLineChange = struct end
JScript supports the use of structures, but not the declaration of new ones.
The TextLineChange type exposes the following members.
Methods
| Name | Description | |
|---|---|---|

Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
GetHashCode | Returns the hash code for this instance. (Inherited from ValueType.) |
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |

Remarks
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.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
