The IFilterCriteria interface provides programmatic access to a single filter condition.

Namespace:  Opalis.QuickIntegrationKit
Assembly:  Opalis.QuickIntegrationKit(in Opalis.QuickIntegrationKit.dll) Version: 3.0.0.0 (3.1.0.1)

Syntax

Visual Basic (Declaration) 
Public 
Interface 
IFilterCriteria

IFilterCriteria

Remarks

The IFilterCriteria interface will typically be used by those OpalisObject classes that require customized querying solutions beyond the filtering support provided by IOpalisRequest.

Examples

CopyC#
public SelectQuery
GetSelectQueryFrom(IOpalisRequest request)
{
	StringBuilder conditions = 
new StringBuilder();

foreach (IFilterCriteria
filter 
in request.Filters)
	{
	
if (conditions.Length != 
0)	 
			conditions.Append(
" AND "); 

		conditions.Append(filter.Name);

	
switch (filter.Relation)
		{
		 
case Relation.EqualTo:
				conditions.Append(
"=");
			
break;

		
case Relation.NotEqualTo:
				conditions.Append(
"<>");

		
// ...
	}

		conditions.AppendFormat(
"'{0}'",
filter.Value.AsString);
}


string className =
request.Inputs[
"Class Name"].AsString;

return
SelectQuery(className, conditions);
}
