Name
IsCustomFunction
Synopsis
IsCustomFunction( )
Returns true
if the specified
Name
is that of a user-defined function.
The following example uses IsCustomFunction( )
to
determine whether Mean
is a user-defined function.
The IsDefined( )
function makes sure the name
exists before testing it with IsCustomFunction( )
.
If you attempt to evaluate a name that doesn’t exist
with IsCustomFunction( )
, ColdFusion throws an
error.
<cfscript> if(IsDefined('Mean') and IsCustomFunction(Mean)){ WriteOutput("Mean is a custom function!"); } else{ WriteOutput("Mean is not a custom function!"); } </cfscript>
