Detailed Description

An ordered collection of expressions identified by name or index.

Expression lists can be created with mi::neuraylib::IExpression_factory::create_expression_list().

Member Function Documentation

◆ add_expression()

virtual Sint32 mi::neuraylib::IExpression_list::add_expression ( const char *  name,
const IExpression *  expression 
)
pure virtual

Adds an expression at the end of the list.

Returns
- 0: Success.
  • -1: Invalid parameter (NULL pointer).
  • -2: There is already an expression mapped to name in the list.

◆ get_expression() [1/4]

template<class T>
const T * mi::neuraylib::IExpression_list::get_expression ( const char *  name) const
inline

Returns the expression for name, or NULL if there is no such expression.

The index-based overload get_expression<T>(const char*)constis faster than this name-based overload and should be preferred if the index is known.

◆ get_expression() [2/4]

virtual const IExpression * mi::neuraylib::IExpression_list::get_expression ( const char *  name) const
pure virtual

Returns the expression for name, or NULL if there is no such expression.

The index-based overload get_expression(const char*)constis faster than this name-based overload and should be preferred if the index is known.

◆ get_expression() [3/4]

template<class T>
const T * mi::neuraylib::IExpression_list::get_expression ( Size  index) const
inline

Returns the expression for index, or NULL if there is no such expression.

This index-based overload is faster than the name-based overload get_expression<T>(const char*)constand should be preferred if the index is known.

Note
Expression lists for defaults and enable-if conditions might not contain an expression for every parameter. Therefore, indices in such lists are not guaranteed to match the parameter indices.

◆ get_expression() [4/4]

virtual const IExpression * mi::neuraylib::IExpression_list::get_expression ( Size  index) const
pure virtual

Returns the expression for index, or NULL if there is no such expression.

This index-based overload is faster than the name-based overload get_expression(const char*)constand should be preferred if the index is known.

Note
Expression lists for defaults and enable-if conditions might not contain an expression for every parameter. Therefore, indices in such lists are not guaranteed to match the parameter indices.

◆ get_index()

virtual Size mi::neuraylib::IExpression_list::get_index ( const char *  name) const
pure virtual

Returns the index for the given name, or -1 if there is no such expression.

◆ get_name()

virtual const char * mi::neuraylib::IExpression_list::get_name ( Size  index) const
pure virtual

Returns the name for the given index, or NULL if there is no such expression.

◆ get_size()

virtual Size mi::neuraylib::IExpression_list::get_size ( ) const
pure virtual

Returns the number of elements.

◆ set_expression() [1/2]

virtual Sint32 mi::neuraylib::IExpression_list::set_expression ( const char *  name,
const IExpression *  expression 
)
pure virtual

Sets an expression identified by name.

The index-based overload set_expression(const char*,const IExpression*) is faster than this name-based overload and should be preferred if the index is known.

Returns
- 0: Success.
  • -1: Invalid parameter (NULL pointer).
  • -2: There is no expression mapped to name in the list.

◆ set_expression() [2/2]

virtual Sint32 mi::neuraylib::IExpression_list::set_expression ( Size  index,
const IExpression *  expression 
)
pure virtual

Sets an expression at a given index.

This index-based overload is faster than the name-based overload set_expression(const char*,const IExpression*) and should be preferred if the index is known.

Returns
- 0: Success.
  • -1: Invalid parameter (NULL pointer).
  • -2: index is out of bounds.
