Member Function Documentation

contains_and()

virtual bool wmtk::components::image_simulation::expression_parser::Expression::contains_and ( ) const

inlinevirtual

Checks if the expression contains a logical AND operation.

Reimplemented in wmtk::components::image_simulation::expression_parser::NotExpr, wmtk::components::image_simulation::expression_parser::AndExpr, and wmtk::components::image_simulation::expression_parser::OrExpr.

contains_not()

virtual bool wmtk::components::image_simulation::expression_parser::Expression::contains_not ( ) const

inlinevirtual

Checks if the expression contains a logical NOT operation.

Reimplemented in wmtk::components::image_simulation::expression_parser::NotExpr, wmtk::components::image_simulation::expression_parser::AndExpr, and wmtk::components::image_simulation::expression_parser::OrExpr.

contains_or()

virtual bool wmtk::components::image_simulation::expression_parser::Expression::contains_or ( ) const

inlinevirtual

Checks if the expression contains a logical OR operation.

Reimplemented in wmtk::components::image_simulation::expression_parser::NotExpr, wmtk::components::image_simulation::expression_parser::AndExpr, and wmtk::components::image_simulation::expression_parser::OrExpr.

eval()

virtual bool wmtk::components::image_simulation::expression_parser::Expression::eval ( const CellTag &  tags ) const

pure virtual

Evaluates the expression against a given set of tags.

Parameters

tags	The tags evaluated against the boolean expression.

Returns

true If the expression is satisfied by the provided tags.

false Otherwise.

Implemented in wmtk::components::image_simulation::expression_parser::TagExpr, wmtk::components::image_simulation::expression_parser::EmptyExpr, wmtk::components::image_simulation::expression_parser::NotExpr, wmtk::components::image_simulation::expression_parser::AndExpr, and wmtk::components::image_simulation::expression_parser::OrExpr.

tags_involved()

virtual CellTag wmtk::components::image_simulation::expression_parser::Expression::tags_involved ( ) const

pure virtual

Returns the set of tags involved in this expression.

This is useful for intent operations to determine which tags are relevant for the operation.

Returns

CellTag The set of tags involved in this expression.

Implemented in wmtk::components::image_simulation::expression_parser::TagExpr, wmtk::components::image_simulation::expression_parser::EmptyExpr, wmtk::components::image_simulation::expression_parser::NotExpr, wmtk::components::image_simulation::expression_parser::AndExpr, and wmtk::components::image_simulation::expression_parser::OrExpr.

to_string()

virtual std::string wmtk::components::image_simulation::expression_parser::Expression::to_string ( ) const

pure virtual

Converts the expression to its string representation. Mainly for debugging purposes.

Returns

std::string The string representation of the expression.

Implemented in wmtk::components::image_simulation::expression_parser::TagExpr, wmtk::components::image_simulation::expression_parser::EmptyExpr, wmtk::components::image_simulation::expression_parser::NotExpr, wmtk::components::image_simulation::expression_parser::AndExpr, and wmtk::components::image_simulation::expression_parser::OrExpr.
