Parameters
Parameter |
Description |
|---|---|
binaryObject |
A binary object returned by ObjectSave function. |
filepath |
A string specifying the path to a file containing a serialized complex object, such as a query or CFC, or a variable that is a serializable binary representation of a complex object. This parameter must be the name of a file or an object returned by the ObjectSave function. |
Usage
This function is useful for handling dynamic data that has a relatively long period of usefulness and takes substantial time or resources to obtain. It lets you save the data in a file and use it in multiple application instances. For example, you can create a CFC that stores a query that takes long time to run and retrieves infrequently updated data. If you use the ObjectSave function to initially save the CFC as a file, you can then deserialize the CFC file on future application starts and improve application performance.
Example
<h3>Loading and saving an object.</h3>
<!--- Create the component object. --->
<cfobject component="tellTime" name="tellTimeObj">
<!--- Save the component object to a file. --->
<cfset ObjectSave(tellTimeObj, "data.out")/>
<!--- Load the component object again. --->
<cfset ObjLoaded = ObjectLoad("data.out") >
<!--- Invoke the methods from loaded objects. --->
<cfinvoke component="#ObjLoaded#" method="getLocalTime" returnvariable="localTime">
<cfinvoke component="#ObjLoaded#" method="getUTCTime" returnvariable="UTCTime">
<!--- Display the results. --->
