Table 16–2 (Cont.) Subprograms for Querying and Validating Geometric Segments
Subprogram Description
SDO_LRS.GET_NEXT_SHAPE_PT Returns the next shape point on a geometric
segment after a specified measure value or
LRS point.
SDO_LRS.GET_NEXT_SHAPE_PT_
MEASURE
Returns the measure value of the next shape
point on a geometric segment after a specified
measure value or LRS point.
SDO_LRS.GET_PREV_SHAPE_PT Returns the previous shape point on a
geometric segment before a specified measure
value or LRS point.
SDO_LRS.GET_PREV_SHAPE_PT_
MEASURE
Returns the measure value of the previous
shape point on a geometric segment before a
specified measure value or LRS point.
SDO_LRS.IS_GEOM_SEGMENT_
Checks if an LRS segment is defined correctly.
DEFINED
SDO_LRS.IS_MEASURE_DECREASING Checks if the measure values along an LRS
segment are decreasing (that is, descending in
numerical value).
SDO_LRS.IS_MEASURE_INCREASING Checks if the measure values along an LRS
segment are increasing (that is, ascending in
numerical value).
SDO_LRS.IS_SHAPE_PT_MEASURE Checks if a specified measure value is a shape
point on a geometric segment.
SDO_LRS.MEASURE_RANGE Returns the measure range of a geometric
segment, that is, the difference between the
start measure and end measure.
SDO_LRS.MEASURE_TO_PERCENTAGE Returns the percentage (0 to 100) that a
specified measure is of the measure range of a
geometric segment.
SDO_LRS.PERCENTAGE_TO_MEASURE Returns the measure value of a specified
percentage (0 to 100) of the measure range of a
geometric segment.
SDO_LRS.LOCATE_PT Returns the point located at a specified
distance from the start of a geometric segment.
SDO_LRS.PROJECT_PT Returns the projection point of a specified
point. The projection point is on the geometric
segment.
