GetPositionAtOffset(Int32,Predicate<Tag>) Method

Returns the position at an offset of the current position, optionally not counting some positions.

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Function GetPositionAtOffset( _
   ByVal offset As System.Integer, _
   ByVal tagFilter As System.Predicate(Of Tag) _
) As C1TextPointer

public C1TextPointer GetPositionAtOffset( 
   System.int offset,
   System.Predicate<Tag> tagFilter
)

Parameters

offset: The offset.
tagFilter: A predicate that can be called to check if a Tag should count as offset. The predicate should return true iff the tag doesn't count. Can be null, which means no filter.

Return Value

A new position at the offset indicated, or null if the offset goes off the document.

Remarks

This method can be used to linearly traverse a C1Document tree.

Start and end tags in each C1TextElement count as items for the traverse, for instance if the position is in an element with children, a position at offset 1 will be the C1TextElement.ContentStart of the C1TextElement where this C1TextPointer is positioned.

If this C1TextPointer is positioned in a C1Run then it traverses the text of the C1Run.
