gn:act calculateDrivingDistance

gn:act_calculateDrivingDistance

Description

Action is used to calculate driving distance between two GPS coordinates and store the result into target

In order for this action to work, an internet connection must be active because the calculations are done by OSRM server.

Action returns

void

Action signatures

Calculate driving distance

[gn:act_calculateDrivingDistance]|[target,source1,source2]

Parameter	Description
target	target into which calculated driving distance will be stored Valid targets: number
source1	source from where gps coordinate will be used for calculation Valid sources: gps
source2	source from where gps coordinate will be used for calculation Valid sources: gps

Example

@+id/deviceKm - target

@+id/gpsInput - source1

@+id/deviceGps - source2

⤷ [gn:act_calculateDrivingDistance]|[@+id/deviceKm,@+id/gpsInput,@+id/deviceGps]

Calculate driving distance with callback action

[gn:act_calculateDrivingDistance]|[target,source1,source2;;eventWidgetId,event]

Parameter	Description
target	target into which calculated driving distance will be stored Valid targets: number
source1	source from where gps coordinate will be used for calculation Valid sources: gps
source2	source from where gps coordinate will be used for calculation Valid sources: gps
eventWidgetId	target on which defined event will be executed Valid sources: number
event	event which will be fired after action is executed Valid sources: hardcoded

Example

@+id/deviceKm - target

@+id/gpsInput - source1

@+id/deviceGps - source2

@+id/onDistanceReceive - callback widget

gn:act_set - callback action

⤷ [gn:act_calculateDrivingDistance]|[@+id/deviceKm,@+id/gpsInput,@+id/deviceGps;;@+id/onDistanceReceive,gn:act_set]

Calculate driving distance and store result into rows

[gn:act_calculateDrivingDistance]|[rowsTarget,source1,source2,searchColumnName,searchColumnValueId;targetColumnName]

Parameter	Description
target	target into which calculated driving distance will be stored Valid targets: number
source1	source from where gps coordinate will be used for calculation Valid sources: gps
source2	source from where gps coordinate will be used for calculation Valid sources: gps
searchColumnName	rows column name which will be searched for specific searchColumnValue Valid sources: hardcoded
searchColumnValueId	source from which the value will be used for matching correct row by checking searchColumnName column Valid sources: any source
targetColumnName	rows column name where the calculated driving distance will be stored Valid sources: hardcoded

Example

@variable/finalDeviceList - target

@+id/gpsInput - source1

@+id/deviceGps - source2

devices_inventoryNumber - searchColumnName

@variable/deviceNumber - searchColumnValueId

device_km - targetColumnName

⤷ [gn:act_calculateDrivingDistance]|[@variable/finalDeviceList,@+id/gpsInput,@+id/deviceGps,devices_inventoryNumber;@variable/deviceNumber,device_km]

Calculate driving distance and store result into rows with callback action

[gn:act_calculateDrivingDistance]|[rowsTarget,sourceColumnName,source,searchColumnName,searchColumnValueId;numericTargetColumnName,stringTargetColumnName,stringSuffix;eventWidgetId,event]

Parameter	Description
target	target into which calculated driving distance will be stored Valid targets: number
sourceColumnName	column from where gps coordinate will be used for calculation Valid sources: gps
source	source from where gps coordinate will be used for calculation Valid sources: gps
searchColumnName	rows column name which will be searched for specific searchColumnValue Valid sources: hardcoded
searchColumnValueId	source from which the value will be used for matching correct row by checking searchColumnName column Valid sources: any source
numericTargetColumnName	rows column name where the calculated driving distance will be stored as number Valid sources: hardcoded
stringTargetColumnName	rows column name where the calculated driving distance will be stored as text Valid sources: hardcoded
stringSuffix	suffix value displayed in stringTargetColumnName Valid sources: text
eventWidgetId	target on which defined event will be executed Valid sources: number
event	event which will be fired after action is executed Valid sources: hardcoded

Example

@variable/finalDeviceList - rows with devices

devices_gps - column in finalDeviceList variable, with GPS

@+id/gpsInput - widget with GPS position

devices_km - target column, which will store result in meters, like 1200

devices_kmText - target column, which will store result in text view, like "1,2 km"

@variable/km - text variable wich contains " km" text

@+id/onDistanceArrived - callback widget

gn:act_set - callback action

⤷ [gn:act_calculateDrivingDistance]|[@variable/finalDeviceList,devices_gps,@+id/gpsInput;devices_km,devices_kmText,@variable/km;@+id/onDistanceArrived,gn:act_set]

Workflow

for each row in "@variable/calculateDrivingDistance_storeResultIntoRowsWithCallbackAction_rowsResult": - get the datatype GPS value of the column named "devicesFullInfo_gps". - asynchronously connect to our osrm server and send startPoint GPS "@variable/calculateDrivingDistance_storeResultIntoRowsWithCallbackAction_pointOne" and endPoint GPS value of column "devicesFullInfo_gps" and get the distance and store it into number datatype and then into row as column "devices_km" and store same result distance into text datatype, add suffix "@variable/calculateDrivingDistance_storeResultIntoRowsWithCallbackAction_rowsResult_km" and store it into "devices_kmText" column into row. - execute callback on widget "@+id/myCallbackBlock" for action "gn:act_set"
