Detailed Description

An element handler converts an IConfigurationElement into a corresponding expression object.

The class should be subclassed by clients wishing to provide an element handler for special expressions.

berry::ElementHandler::berryObjectMacro

(

ElementHandler

)

Create() [1/2]

virtual SmartPointer<Expression> berry::ElementHandler::Create ( ExpressionConverter *  converter, Poco::XML::Element *  element  )

virtual

Creates the corresponding expression for the given DOM element. This is an optional operation that is only required if the handler supports conversion of DOM elements.

Parameters

converter	the expression converter used to initiate the conversion process
element	the DOM element to convert

Returns

the corresponding expression

Exceptions

CoreException

if the conversion failed

Since

3.3

Create() [2/2]

virtual SmartPointer<Expression> berry::ElementHandler::Create ( ExpressionConverter *  converter, SmartPointer< IConfigurationElement >  config  )

pure virtual

Creates the corresponding expression for the given configuration element.

Parameters

converter	the expression converter used to initiate the conversion process
config	the configuration element to convert

Returns

the corresponding expression

Exceptions

CoreException

if the conversion failed

GetDefault()

static ElementHandler::Pointer berry::ElementHandler::GetDefault ( )

static

The default element handler which can cope with all XML expression elements defined by the common expression language.

Returns

the default element handler

ProcessChildren() [1/2]

virtual void berry::ElementHandler::ProcessChildren ( ExpressionConverter *  converter, Poco::XML::Element *  element, SmartPointer< CompositeExpression >  expression  )

protectedvirtual

Converts the children of the given DOM element and adds them to the given composite expression.

Note this is an internal method and should not be called by clients.

Parameters

converter	the converter used to do the actual conversion
element	the DOM element for which the children are to be processed
expression	the composite expression representing the result of the conversion

Exceptions

CoreException

if the conversion failed

Since

3.3

ProcessChildren() [2/2]

virtual void berry::ElementHandler::ProcessChildren ( ExpressionConverter *  converter, SmartPointer< IConfigurationElement >  element, SmartPointer< CompositeExpression >  expression  )

protectedvirtual

Converts the children of the given configuration element and adds them to the given composite expression.

Note this is an internal method and should not be called by clients.

Parameters

converter	the converter used to do the actual conversion
element	the configuration element for which the children are to be processed
expression	the composite expression representing the result of the conversion

Exceptions

CoreException

if the conversion failed
