Detailed Description

A status object describing information about an expression tree. This information can for example be used to decide whether a expression tree as to be reevaluated if the value of some variables changes.

This class is not intended to be extended by clients.

AddAccessedPropertyName()

void berry::ExpressionInfo::AddAccessedPropertyName

(

const QString &

name

)

Marks that this expression access this property. It should be the fully qualified property name.

Parameters

name	the fully qualified property name

AddMisBehavingExpressionType()

void berry::ExpressionInfo::AddMisBehavingExpressionType

(

const std::type_info &

clazz

)

Adds the given class to the list of misbehaving classes.

Parameters

clazz

the class to add.

AddVariableNameAccess()

void berry::ExpressionInfo::AddVariableNameAccess

(

const QString &

name

)

(

ExpressionInfo *

other

)

Merges this reevaluation information with the given info.

Parameters

other

the information to merge with

MergeExceptDefaultVariable()

void berry::ExpressionInfo::MergeExceptDefaultVariable

(

ExpressionInfo *

other

)
