Elegant way to distinct Path or Entry key
- by sum1stolemyname
I have an application loading CAD data (Custom format), either from the local filesystem specifing an absolute path to a drawing or from a database.
Database access is realized through a library function taking the drawings identifier as a parameter.
the identifiers have a format like ABC 01234T56-T, while my paths a typical windows Paths (eg x:\Data\cadfiles\cadfile001.bin).
I would like to write a wrapper function Taking a String as an argument which can be either a path or an identifier which calls the appropriate functions to load my data.
Like this:
Function CadLoader(nameOrPath : String):TCadData;
My Question: How can I elegantly decide wether my string is an idnetifier or a Path to a file?
Use A regexp? Or just search for '\' and ':', which are not appearing in the Identifiers?
