Class BufferResultValidator
java.lang.Object
org.locationtech.jts.operation.buffer.validate.BufferResultValidator
Validates that the result of a buffer operation
is geometrically correct, within a computed tolerance.
This is a heuristic test, and may return false positive results (I.e. it may fail to detect an invalid result.) It should never return a false negative result, however (I.e. it should never report a valid result as invalid.)
This test may be (much) more expensive than the original buffer computation.

Checks whether the geometry buffer is valid, and returns an error message if not.- Parameters:
g

-- Returns:
- an appropriate error message or null if the buffer is valid

getErrorIndicator
Gets a geometry which indicates the location and nature of a validation failure.If the failure is due to the buffer curve being too far or too close to the input, the indicator is a line segment showing the location and size of the discrepancy.
- Returns:
- a geometric error indicator or null if no error was found
