Class MBArrayStop

Object

MBArrayStop

public class MBArrayStop
extends Object

Wrapper for a "stop" in an array function (See MBFunction.isArrayFunction()), providing methods to access the stop key and stop value array, as well as a method to reduce it from an array stop to a single-value stop (for a given index).

For example, the following "stops" list contains two MBArrayStops. (for each stop, the stop value is an array).

  'stops': [
          // [stopkey, stopValueArray]
             [0,       [0,10]],
             [100,     [2,15]]
    ]
 

Used by MBFunction.splitArrayFunction() to split an array function into multiple functions, one for each dimension in the output array.

Method Detail

getStopKey

public Object getStopKey()

Get the stop key for this stop.

For example, for the following MBArrayStop: [1, [0,10]] the output of stop.getStopKey() is 1.

Returns:

stop key

getStopValueCount

public int getStopValueCount()

Returns the size of the array of stop values.

For example, for the following MBArrayStop: [0, [0,10]] the output of stop.getStopValueCount() is 2.

Returns:

the size of the array of stop values.

getStopValue

public Object getStopValue(int idx)

Returns the value from the stop value array at the provided index.

For example, for the following MBArrayStop: [0, [0,10]], the output of stop.getStopValue(1) is 10.

Parameters:

idx - The index to look up in the stop value array.

Returns:

The value from the stop value array at the provided index.

reducedToIndex

public JSONArray reducedToIndex(int idx)

Returns the JSON for a new stop derived from this stop, but reduced to a single-value stop with the value from the provided index.

For example, for the MBArrayStop [0, [0,10]], The output of stop.reducedToIndex(1) is the following new stop: [0, 10]

Parameters:

idx - The index to use as the single value for the new stop.

Returns:

A new stop, with a single stop value rather than a stop value array.
