Detailed Description

A default implementation of an evaluation context.

Clients may instantiate this default context. The class is not intended to be subclassed by clients.

Since: 3.0

Definition at line 41 of file berryEvaluationContext.h.

Constructor & Destructor Documentation

berry::EvaluationContext::EvaluationContext	(	IEvaluationContext *	parent,
		const Object::ConstPointer &	defaultVariable
	)

Create a new evaluation context with the given parent and default variable.

Parameters

parent	the parent context. Can be `null`.
defaultVariable	the default variable

Definition at line 21 of file berryEvaluationContext.cpp.

berry::EvaluationContext::EvaluationContext	(	IEvaluationContext *	parent,
		const Object::ConstPointer &	defaultVariable,
		const std::vector< IVariableResolver * > &	resolvers
	)

Create a new evaluation context with the given parent and default variable.

Parameters

parent	the parent context. Can be `null`.
defaultVariable	the default variable
resolvers	an array of `IVariableResolvers` to resolve additional variables.

See also: #resolveVariable(String, Object[])

Member Function Documentation

void berry::EvaluationContext::AddVariable	(	const QString &	name,
		const Object::ConstPointer &	value
	)

overridevirtual

Adds a new named variable to this context. If a variable with the name already exists the new one overrides the existing one.

Parameters

name	the variable's name
value	the variable's value

Implements berry::IEvaluationContext.

Definition at line 74 of file berryEvaluationContext.cpp.

References berry::SmartPointer< TObjectType >::IsNotNull().

bool berry::EvaluationContext::GetAllowPluginActivation ( ) const

overridevirtual

Returns whether this evaluation context supports plug-in activation. If not set via setAllowPluginActivation(boolean) the parent value is returned. If no parent is set false is returned.

Returns: whether plug-in activation is supported or not

Since: 3.2

Implements berry::IEvaluationContext.

Definition at line 60 of file berryEvaluationContext.cpp.

References berry::IEvaluationContext::GetAllowPluginActivation().

Object::ConstPointer berry::EvaluationContext::GetDefaultVariable ( ) const

overridevirtual

Returns the default variable.

Returns: the default variable or null if no default variable is managed.

Implements berry::IEvaluationContext.

Definition at line 50 of file berryEvaluationContext.cpp.

IEvaluationContext * berry::EvaluationContext::GetParent ( ) const

overridevirtual

Returns the parent context or null if this is the root of the evaluation context hierarchy.

Returns: the parent evaluation context or null

Implements berry::IEvaluationContext.

Definition at line 38 of file berryEvaluationContext.cpp.

IEvaluationContext * berry::EvaluationContext::GetRoot ( ) const

overridevirtual

Returns the root evaluation context.

Returns: the root evaluation context

Implements berry::IEvaluationContext.

Definition at line 43 of file berryEvaluationContext.cpp.

References berry::IEvaluationContext::GetRoot().

Object::ConstPointer berry::EvaluationContext::GetVariable ( const QString & name ) const

overridevirtual

Returns the variable managed under the given name.

Parameters

name	the variable's name

Returns: the variable's value or null if the content doesn't manage a variable with the given name

Implements berry::IEvaluationContext.

Definition at line 93 of file berryEvaluationContext.cpp.

References berry::IEvaluationContext::GetVariable().

Object::ConstPointer berry::EvaluationContext::RemoveVariable ( const QString & name )

overridevirtual

Removes the variable managed under the given name from this evaluation context.

Parameters

name	the variable's name

Returns: the currently stored value or null if the variable doesn't exist

Implements berry::IEvaluationContext.

Definition at line 83 of file berryEvaluationContext.cpp.

Object::ConstPointer berry::EvaluationContext::ResolveVariable	(	const QString &	name,
		const QList< Object::Pointer > &	args
	)		const

overridevirtual

Resolves a variable for the given name and arguments. This method can be used to dynamically resolve variable such as plug-in descriptors, resources, etc. The method is used by the resolve expression.

Parameters

name	the variable to resolve
args	an object array of arguments used to resolve the variable

Returns: the variable's value or null if no variable can be resolved for the given name and arguments

Exceptions

CoreException if an errors occurs while resolving the variable

Implements berry::IEvaluationContext.

Definition at line 115 of file berryEvaluationContext.cpp.

References berry::IVariableResolver::Resolve(), and berry::IEvaluationContext::ResolveVariable().

void berry::EvaluationContext::SetAllowPluginActivation ( bool value )

overridevirtual

Specifies whether this evaluation context allows activation of plug-ins for testers used in the expression tree. To actual trigger the plug-in loading this flag has to be set to true and the actual test expression must have the attribute forcePluginActivation set to true as well.

Parameters

value whether this evaluation context allows plug-in activation

Since: 3.2

Implements berry::IEvaluationContext.
