Detailed Description

We need to have something that allows one plugin stack to access another plugin stack, so this represents a instantiation of each plugin stack. It also keeps common state: user credentials, security context, and run-time parameters (see set)

Note

Assume a StackInstance (and every instantiated interface under it) is NOT thread-safe. This means, a StackInstance must be used by only one thread at the same time.

Constructor & Destructor Documentation

StackInstance()

dmlite::StackInstance::StackInstance

(

PluginManager *

pm

)

Member Function Documentation

contains()

bool dmlite::StackInstance::contains	(	const std::string &	key	)
throw	(

Checks if the stack instance contains a value associated with the given key.

erase()

void dmlite::StackInstance::erase

(

const std::string &

key

)

Erase a key,value pair from.

Parameters

key	The key of the pair to be erased.

eraseAll()

throw	(
	)

set()

void dmlite::StackInstance::set	(	const std::string &	key,
		const boost::any &	value
	)

Set a key-value pair associated with this context. This can be used to pass advanced parameters to and from the plugins.

Parameters

key	The key.
value	The value.

setSecurityContext()

void dmlite::StackInstance::setSecurityContext

(

const SecurityContext &

ctx
