The problems handler returns a character vector of parse errors and can be used to validate input of any type for which wk_handle() is defined.

wk_problems(handleable, ...)

wk_problems_handler()

Arguments

handleable

A geometry vector (e.g., wkb(), wkt(), xy(), rct(), or sf::st_sfc()) for which wk_handle() is defined.

...

Passed to the wk_handle() method.

Value

A character vector of parsing errors. NA signifies that there was no parsing error.

Examples

wk_problems(new_wk_wkt(c("POINT EMTPY", "POINT (20 30)")))
#> [1] "Expected '(' or 'EMPTY' but found 'EMTPY' (:6)" #> [2] NA
wk_handle( new_wk_wkt(c("POINT EMTPY", "POINT (20 30)")), wk_problems_handler() )
#> [1] "Expected '(' or 'EMPTY' but found 'EMTPY' (:6)" #> [2] NA
