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.

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

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.

void berry::ExpressionInfo::AddVariableNameAccess

(

const QString &

name

)

Marks the given variable as accessed.

Parameters

name	the accessed variable

QSet< QString > berry::ExpressionInfo::GetAccessedPropertyNames

(

)

const

Returns the set of accessed properties.

Returns

the set of accessed properties, or an empty array

Definition at line 65 of file berryExpressionInfo.cpp.

QSet< QString > berry::ExpressionInfo::GetAccessedVariableNames

const

Returns the set off accessed variables.

Returns

the set off accessed variables

QSet< QString > berry::ExpressionInfo::GetMisbehavingExpressionTypes

(

)

const

Returns the set of expression types which don't implement the new (} method. If one expression didn't implement the method the expression tree no optimizations can be done. Returns null if all expressions implement the method. the set of expression types which don't implement the computeReevaluationInfo method.

Definition at line 30 of file berryExpressionInfo.cpp.

bool berry::ExpressionInfo::HasSystemPropertyAccess

(

)

const

Returns true if the system property is accessed by the expression tree.

Returns

whether the system property is accessed or not

Definition at line 42 of file berryExpressionInfo.cpp.

void berry::ExpressionInfo::MarkDefaultVariableAccessed

(

)

Marks the default variable as accessed.

Definition at line 36 of file berryExpressionInfo.cpp.

void berry::ExpressionInfo::MarkSystemPropertyAccessed

(

)

Marks the system property as accessed.

Definition at line 48 of file berryExpressionInfo.cpp.

void berry::ExpressionInfo::Merge

(

ExpressionInfo *

other

)

Merges this reevaluation information with the given info.

Parameters

other

the information to merge with

Definition at line 88 of file berryExpressionInfo.cpp.

void berry::ExpressionInfo::MergeExceptDefaultVariable
