Chapter 3: ColdFusion Functions
Note:
Use the This scope to access component metadata inside the CFC. The This scope is available
at runtime in the component body and in the CFC methods. It is used to read and write variables that
are present during the life of the component.
For more information, see “Using introspection to get information about components” in
Chapter 10, “Building and Using ColdFusion Components,” in
ColdFusion MX Developer’s
Guide
.
Example
The following example uses the
cfdump
tag to display metadata for the utilities CFC that is used
by the ColdFusion component browser. It also displays the names and data types of the fields in
the cfdocexamples database Employees table.
<!--- Create an instance of the Component Explorer utilities CFC.
and get its metadata --->
<cfscript>
componentutils = createObject("component", "cfide.componentutils.utils");
utilmetadata = getMetaData(componentutils);
</cfscript>
<h4>Metadata for the CFC component utilities</h4>
<cfdump var="#utilmetadata#">
<!--- use GetMetadata to get the names and data types of the fields in the
cfdocexamples Employees table --->
