Method Detail

applyUnaryOp

public static void applyUnaryOp(GeoTimeSerie result,
                                GeoTimeSerie gts,
                                GTSOpsHelper.GTSUnaryOp op)

Apply a unary operator to the values of a GTS, resulting in another GTS. Location and elevation info are copied to the result GTS.

Parameters:

result - The resulting GTS, for each tick of gts, result[tick]=op(gts[tick]).

gts - The GTS from where to take the values from.

op - The operator to apply to the values.

handleBucketization

public static void handleBucketization(GeoTimeSerie result,
                                       GeoTimeSerie gts1,
                                       GeoTimeSerie gts2)

Set the bucketize parameters of the result GTS according to those of gts1 and gts2. If both GTSs have the same bucket span and buckets are aligned, the result covers the common buckets of gts1 and gts2. In all the other case, the result is not bucketized.

Parameters:

result - The GTS whose bucketize parameters must be set (or not).

gts1 - One of the two GTSs to get the bucketize parameters from.

gts2 - One of the two GTSs to get the bucketize parameters from.

applyBinaryOp

public static void applyBinaryOp(GeoTimeSerie result,
                                 GeoTimeSerie gts1,
                                 GeoTimeSerie gts2,
                                 GTSOpsHelper.GTSBinaryOp op)

applyBinaryOp

public static void applyBinaryOp(GeoTimeSerie result,
                                 GeoTimeSerie gts1,
                                 GeoTimeSerie gts2,
                                 GTSOpsHelper.GTSBinaryOp op,
                                 boolean copyGts1Location)

Apply a binary operator to the values of two GTSs, resulting in a single GTS. Only common ticks are considered.

Parameters:

result - GTS containing all the results. ie for each common tick to gts1 and gts2, result[tick]=op(gts1[tick], gts2[tick]).

gts1 - First GTS to take values from.

gts2 - Second GTS to take values from.

op - Operator which will compute the value to be put in result.

copyGts1Location - Whether to copy the location and elevation of gts1 to result. If false, points in result have no location and no elevation.
