I was wondering if someone can see why I can't seem to get my singleton
from the following function?
<cffunction
access="private"
name="getInstance"
output="false"
returntype="Object"
displayname="Get Instance"
hint="Returns an instance of the object, gets it
from the persistent scope if the class is a singleton.">
<cfscript>
var mySingletonPath = "";
// Check if this object is a singleton
if ( isSingleton() )
{
mySingletonPath =
getSingletonScope() & ".hash" & getClassPathAsHash() & ".hash" & hash(
getMetaData( this ).name );
// Check if the singleton is
instantiated
if ( NOT isDefined( mySingletonPath
) )
{
setInstanceVariable(
variableName = "initialized", value = true );
setClassVariable(
variableName = "hash" & hash( getMetaData( this ).name ), value = this,
scope = getSingletonScope() );
}
// Return the Singleton
//getClassVariable( variableName =
"hash" & hash( getMetaData( this ).name ), scope = getSingletonScope()
).dumpInstance();abort();
return getClassVariable(
variableName = "hash" & hash( getMetaData( this ).name ), scope =
getSingletonScope() );
}
setInstanceVariable( variableName =
"initialized", value = true );
// Return a new instance of this object
return this;
</cfscript>
</cffunction>
Let's say if I set a variable in the object with a value of "1",
instantiate the object, change the value to "2" save the object and
instantiate it again, and then call dumpInstance() I expect the value to
be "1" not "2".
When I uncomment the following line it outputs the expected result, i.e.
an instance variable with the value "1"
//getClassVariable( variableName = "hash" & hash( getMetaData( this
).name ), scope = getSingletonScope() ).dumpInstance();abort();
But when I later dump it from the file that instantiates the object it
outputs "2"
FormProcess = new ( "com.pacificMomentum.data.FormProcess" ).init();
FormProcess.dumpInstance();abort();
PS.
dumpInstance() is one of my own methods which dumps instance variables
BTW.
The init() method in the object returns getInstance() BTW i.e.
return getInstance();
