Since the cache is empty, we make a request and save the data to the cache exp: (Date.now() + msToExpire) = 17:00 + 30 min = 17:30. I have added IFeatureClass.Search (queryFilter, true) to search the feature again by FID and save in a cursor then use the 'feature.getValue' to read the attribute. More than 14.3 million 211 connections to help were made in 2017. I have modified the program and successfully read the feature attribute 'POSTCODE'. And let's imagine that the msToExpire = 30 min. 211 is a universally respected and growing national model. And in the next call of this function you compare exp from your save element with current time Date.now().įor example the cache is empty, and you call getOrSetCache at 17:00. fields to the feature class using arcpyUse an insert cursor to populate the 1. If this element is not in the cache, you make a request and after receive data, you save in to ls, and set time to expire as date.now() + msToExpire. Esri ArcGIS Pro display configuration Thank you for your feedback. When you call getOrSetCache, you pass msToExpire to arguments. This code works, but I couldn't understand how, is there any other better way to cache with expiration date? Solution These easy-to-create and flexible cursor structures are in-memory collections of records that can be constrained through the use of filters applied through the QueryFilter and. My question is more about how it manages to save in cache with an expiration date, and when the date expires, make the request again ArcObjects cursor structures provide you with the ability to query, insert, update, and delete records from FeatureClasses and Tables. The older version of InsertCursor arcpy.InsertCursor() will allow you to add data to a geometric network and maintain a decent level of performance.Guys I have this code that saves my products in cache, I would like to better understand how it works, getItemById(id) )) That solution does work, however it's much slower. a geodatabase using a cursor (recycling or non recycling), the spatial reference of the feature, as returned by NextFeature, is guaranteed to be in the spatial reference that you specified in the query filter. The solution suggested by ESRI is to insert the data into an empty feature class then append the feature class to the geometric network. There is currently a bug (Bug NIM102778) on file with ESRI over this issue. The answer suggested here does not solve the issue if your are trying to use the da.InsertCursor to add data in a Geometric Network. "SystemError: error return without exception set" Because VBA support in ArcGIS is ending after version 10.0, VBA ArcObjects programmers are encouraged to migrate their scripts to other languages. ArcMap and ArcCatalog snippets support running both inside the applications and in a standalone session. Google suggested this answer for the following arcpy.da.InsertCursor error: PYTHONARCOBJECTS.ZIP (22K)- Using ArcObjects in Python. With arcpy.da.InsertCursor(targetFC,fieldnames) as iCur: With arcpy.da.SearchCursor(sourceFC,fieldnames) as sCur: Out_fields = įieldnames = ' for field in fields if field.name not in out_fields] Passing an ICursor to ArcObjects ITableSort. I have added IFeatureClass.Search (queryFilter, true) to search the feature again by FID and save in a cursor then use the feature.getValue to read the attribute. Ive read another post on GIS SE on the same subject that warned against doing this. I have modified the program and successfully read the feature attribute POSTCODE. Update the existing Row in the database corresponding to the current position of the cursor. ![]() Advance the position of the cursor by one and return the Row object at that position. The object ID of the new Row, if there is one, is returned. If you havent inserted your image yet, place the cursor where you want it. Insert a new Row into the database using the property values in the input buffer. # List all field names except the OID field and geometry fields Im trying to pass a cursor (from a querydef with a prefixclause of DISTINCT) to itablesort.cursor. Refer to ArcGIS Pro: Georeferencing a raster entering x,y coordinates for. As long as your source and target FC's have the same number of fields and have the same geometry type, this should work: # Get field objects from source FC More info : Once TrackPan has been called in response to a mouse down event, and the user continues to hold down the right mouse button (for +-1.5 seconds) then ArcObjects will enter a different panning mode which automatically displays the relevant mouse panning cursor depending on the mouse movement.
