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.
