IsNotMap
IsNotMap(variable_name)Returns true if the specified variable does not
map to an object of type Structure, Query, XML Document Object, COM,
CORBA, Java, ColdFusion Component, or web service. This is an
undocumented function in ColdFusion MX. Here’s an
example that attempts to evaluate both a simple value and an object:
<cfset x=1> <cfobject type="Java" action="Create" name="FileReader" class="java.io.FileReader"> <cfoutput> Does x not map to an object? #IsNotMap(x)#<br> Does FileReader not map to an object? #IsNotMap(FileReader)# </cfoutput>
