JScript 支持使用显式接口实现，但不支持声明新显式接口实现。

参数

  • isTopmostGrid
    类型：System.Boolean
    True if the specified object is in topmost grid; otherwise, false.
  • rGridMinX
    类型：System.Double
    The minimum value of X of the grid.
  • rGridMinY
    类型：System.Double
    The minimum value of Y of the grid.
  • touched
    类型：array<System.Boolean[,]
    True if the specified object is touched; otherwise, false.
  • contained
    类型：array<System.Boolean[,]
    True if the specified grid is contained; otherwise, false.
  • cCellsTouched
    类型：System.Int32%
    True if the cells of the grid is touched; otherwise, false.
  • cCellsContained
    类型：System.Int32%
    True if the specified cells of the grid id contained; otherwise, false.
  • fGeometryExceedsGrid
    类型：System.Boolean%
    True if the geometry exceeds the grid; otherwise, false.
  • fHasAmbiguousTouchedCells
    类型：System.Boolean%
    True if the grid has ambiguous touched cells; otherwise, false.

实现

ISqlSpatialGridIndexable.GetGridCoverage(Boolean, Double, Double, Double, Double, Double, Double, Int32, Int32, array<Boolean[,], array<Boolean[,], Int32%, Int32%, Boolean%, Boolean%)
