AddDependencies()

PCP_API void AddDependencies	(	const PcpLayerStackPtr &	layerStack,
		std::unordered_set< std::string > &&	exprVarDependencies
	)

Adds dependencies on the expression variables in exprVarDependencies from layerStack.

AppendDependencyData()

PCP_API void AppendDependencyData

(

PcpExpressionVariablesDependencyData &&

data

)

Moves dependencies in data and appends it to the dependencies in this object.

ForEachDependency()

void ForEachDependency ( const Callback &  callback ) const

inline

Runs the given callback on all of the dependencies in this object.

callback must have the signature:

void(const PcpLayerStack&, const std::unordered_set<std::string>&)

The first argument is the layer stack associated with the expression variables in the second argument.

Definition at line 85 of file expressionVariablesDependencyData.h.

GetDependenciesForLayerStack()

PCP_API const std::unordered_set< std::string > * GetDependenciesForLayerStack

(

const PcpLayerStackPtr &

layerStack

)

const

Returns the expression variable dependencies associated with layerStack.

If no such dependencies have been added, returns nullptr.

IsEmpty()

PCP_API bool IsEmpty

(

)

const

Returns true if any dependencies have been recorded, false otherwise.
