Member Function Documentation

category()

Category Diades::Altarica::BinaryExpression::category ( ) const

inlinevirtual

Expression evaluation: this operation evaluates the expression with the current value associated to the variables that support the Expression. The evaluation is failing if there is a variable of the support that is still free (that is an unassigned variable).

Parameters

value

the Value resulting from the evaluation of the current Expression.

Returns

true if the operation succeeds, false otherwise.Category of an expression

the category o of the Expression. It is way to avoid the use of RTTI and gets a lighter implementation.

Implements Diades::Altarica::Expression.

Definition at line 383 of file Expression.hh.

References Diades::Altarica::Expression::valueType().

isConstant()

virtual bool Diades::Altarica::BinaryExpression::isConstant ( ) const

inlinevirtual

Returns

true if the Expression is constant

Implements Diades::Altarica::Expression.

Definition at line 385 of file Expression.hh.

left()

const Expression& Diades::Altarica::BinaryExpression::left ( ) const

inline

right()

inline

Definition at line 382 of file Expression.hh.

valid()

virtual bool Diades::Altarica::BinaryExpression::valid ( ) const

inlinevirtual

Validity of an Expression

Returns

true if the current Expression is valid.

Implements Diades::Altarica::Expression.

Definition at line 376 of file Expression.hh.

References Diades::Altarica::Expression::valid().

valueType()

virtual const Type& Diades::Altarica::BinaryExpression::valueType ( ) const

virtual

Type of the Value returned by the Expression (lazy computation)

Returns

the Type of the Value.

Implements Diades::Altarica::Expression.
