Class wildex

Parses and compares wildcard expression.

public class wildex

Remarks

Used in "find" functions. For example in wnd.find to compare window name, class name and program. The "find" function creates a wildex instance (which parses the wildcard expression), then calls wildex.Match for each item (eg window) to compare some its property text.

Examples

//This version does not support wildcard expressions.
Document Find1(string name, string date) {
	return Documents.Find(x => x.Name.Eqi(name) && x.Date.Eqi(date));
}

//This version supports wildcard expressions.
//null-string arguments are not compared.
Document Find2(string name, string date) {
	wildex n = name, d = date; //null if the string is null
	return Documents.Find(x => (n == null || n.Match(x.Name)) && (d == null || d.Match(x.Date)));
}

//Example of calling such function.
//Find item whose name is "example" (case-insensitive) and date starts with "2017-".
var item = x.Find2("example", "2017-*");
