	[iid_is(aIID),] out nsQIResult result)

Parameters:

aClass: The class ID of the class whose factory is being requested.
aIID: The interface ID of the interface that the factory's class implements.
result: [out] The reference to return.

nsresult:

NS_OK if successful.
getClassObjectByContractID

Returns the factory object that is used as an intermediary in the creation of instances of the class represented by the contract ID string.

Syntax: 

void nsIComponentManager::getClassObjectByContractID(
	in string aContractID, 
	in nsIIDRef aIID,
	[iid_is(aIID),retval] out nsQIResult result)

Parameters:

	[iid_is(aIID),retval] out nsQIResult result)

Parameters:

aClass: The class ID of the requested class.
aDelegate: Used for aggregation.
aIID: The ID of the requested interface.
result: [out] The reference to return.

nsresult:

NS_OK if successful
createInstanceByContractID

Creates an instance of the class indicated by the contract ID string and returns the interface indicated by the interface ID.

Syntax: 

void nsIComponentManager::createInstanceByContractID(
	in string aContractID,in nsISupports aDelegate,
	in nsIIDRef aIID,
	[iid_is(aIID),retval] out nsQIResult result)

Parameters:

aContractID: The contract ID of the requested class.
