If you don’t know the class of attribute until runtime, use addattrib.
int addpointattrib(int geohandle, string name, <type>defvalue)
int addpointattrib(int geohandle, string name, <type>defvalue[])
Adds a point attribute to the given geometry.
int addpointattrib(int geohandle, string name, <type>defvalue, string typeinfo)
int addpointattrib(int geohandle, string name, <type>defvalue[], string typeinfo)
Adds a point attribute with the given transformation info. See attribtypeinfo for more details.
geohandle
A handle to the geometry to write to. Currently the only valid value is 0
or geoself, which means the current geometry in a node. (This argument may be used in the future to allow writing to other geometries.)
name
The name of the attribute to create.
defvalue
The default value for the attribute and determines the type of attribute to create. String and array attributes cannot have defaults, so only the type is used in those cases.
geohandle
on success, or -1
on failure.
-
If an attribute of the same name already exists, the function will try to convert it to the new type.
