Detailed Description

Describe an expression used by its name (as constants or variables). A single reference is made to a NamedExpression in every Expression (i.e. a NamedExpression is shared).

Member Function Documentation

◆ GetName()

const TCollection_AsciiString& Expr_NamedExpression::GetName ( ) const

◆ IsIdentical()

Standard_Boolean Expr_NamedExpression::IsIdentical ( const Handle< Expr_GeneralExpression > &  Other) const
overridevirtual

Tests if <me> and <Other> define the same expression. This method does not include any simplification before testing.

Implements Expr_GeneralExpression.

◆ IsShareable()

virtual Standard_Boolean Expr_NamedExpression::IsShareable ( ) const
overridevirtual

Tests if <me> can be shared by one or more expressions or must be copied. This method redefines to a True value the GeneralExpression method.

Reimplemented from Expr_GeneralExpression.

◆ SetName()

void Expr_NamedExpression::SetName ( const TCollection_AsciiString name)

◆ String()

TCollection_AsciiString Expr_NamedExpression::String ( ) const
overridevirtual

returns a string representing <me> in a readable way.

Implements Expr_GeneralExpression.
