Método EditPoint2.LessThan

Retornará se o valor de AbsoluteCharOffset chamado do objeto de EditPoint é menor que o do objeto determinado de TextPoint .

Namespace:  EnvDTE80
Assembly:  EnvDTE80 (em EnvDTE80.dll)

Sintaxe

'Declaração
Function LessThan ( _
    Point As TextPoint _
) As Boolean

bool LessThan(
    TextPoint Point
)

bool LessThan(
    [InAttribute] TextPoint^ Point
)

abstract LessThan : 
        Point:TextPoint -> bool

function LessThan(
    Point : TextPoint
) : boolean

Parâmetros

• Point
  Tipo: TextPoint

  Necessário. TextPoint a ser comparado com o objeto de ponto de chamada.

Valor de retorno

Tipo: Boolean
true se Point tem um valor da propriedade maior de AbsoluteCharOffset da propriedade de AbsoluteCharOffset do objeto de ponto de chamada; caso contrário, false.

Comentários

LessThan gerencie ArgumentException se Point não estiver no mesmo documento que o objeto de ponto de chamada. Com o objeto de VirtualPoint , LessThan compara as posições virtuais se o argumento for VirtualPoint. Se não compara as posições físicos.
