Using the GetMetaData function

The CFML GetMetaData function returns a structure containing all the metadata of a CFC instance. This structure contains substantially more data about the CFC than cfdump shows, and includes the following information:

All attributes to the component tag, including any metadata-only attributes, plus the component path.
An array of structures containing full information on each method (function) in the component. This information includes all attributes, including metadata-only function and parameter attributes.
Within each function structure, a Parameters element containing an array of parameters specified by cfargument tags. Information on each parameter includes any metadata-only attributes.
Information about any properties that are specified using the cfproperty tag

For information on how to specify CFC metadata, including how to use component tags and how to specify metadata-only attributes, see Documenting CFCs.

Personally I think the tag would have more value if it returned a named array with methods/properties/etc. instead of an indexed array.. To get at any info you need to loop over the whole array to get at the info you are after.

For example;
getMetaData(obj).functions["myFunction"]
Is easier and quicker to access than
loop over getMetaData(obj)
if getMetaData(obj).functions[ i ] IS "myFunction"
do this and that...
