Detailed Description

Level 1 linear expression (ap_linexpr1_t wrapper).

Level 1 version of linear expressions with scalar or interval coefficients (coeff). Terms are indexed using variable names (var) instead of dimensions (ap_dim_t). Internally, a linexpr1 wraps together a linexpr0 (memory managed) and an environment (holding a reference count).

Constructor & Destructor Documentation

linexpr1::linexpr1 ( ap_linexpr1_t & p )

inlineprotected

Internal use only. Shallow copy (no copy of linexpr0 or environment).

linexpr1::linexpr1	(	const environment &	e,
		const linexpr0 &	x
	)

inline

Creates a new expression from a linexpr0 (copied) and an environment (reference count incremented) associating names to dimensions in linexpr0.

apron::linexpr1::linexpr1	(	const environment &	e,
		ap_linexpr_discr_t	lin_discr = `AP_LINEXPR_SPARSE`,
		size_t	size = `0`
	)

inline

Creates a new null expression.

e associates a variable name to each dimension.
discr whether the expression is sparse (AP_LINEXPR_SPARSE) or dense (AP_LINEXPR_DENSE).
size, for AP_LINEXPR_SPARSE expressions, is the initial number of dimensions in the underlying linexpr0 (new dimensions being added as needed); ignored for AP_LINEXPR_DENSE expressions (the size being always the size of the environment).

linexpr1::linexpr1 ( const linexpr1 & x )

inline

Makes a (deep) copy.

linexpr1::linexpr1	(	const linexpr1 &	x,
		const environment &	e
	)

inline

Makes a (deep) copy of x and extends its environment.

Exceptions

std::invalid_argument if e is not a super-environment of that of x.

linexpr1::~linexpr1 ( )

inline

Frees all space for the expression and coefficients, and decrements the reference count of the environment.

Member Function Documentation

linexpr1::iterator linexpr1::begin ( )

inline

Returns a new iterator to traverse and mutate the linear expression.

linexpr1::const_iterator apron::linexpr1::begin ( ) const

inline

Returns a new constant iterator to traverse the linear expression.

void linexpr1::extend_environment ( const environment & e )

inline

Extends the environment of the expression.

Exceptions

std::invalid_argument if e is not a super-environment of that of *this.

const ap_linexpr1_t * apron::linexpr1::get_ap_linexpr1_t ( ) const

inline

Returns a pointer to the internal APRON object stored in *this.

ap_linexpr1_t * linexpr1::get_ap_linexpr1_t ( )

inline

Returns a pointer to the internal APRON object stored in *this.

coeff & linexpr1::get_cst ( )

inline

Returns a (modifiable) reference to the constant coefficient.

const coeff & apron::linexpr1::get_cst ( ) const

inline

Returns a reference to the constant coefficient.

ap_linexpr_discr_t linexpr1::get_discr ( ) const

inline

Returns the type of underlying linexpr0.

Returns: Either AP_LINEXPR_SPARSE or AP_LINEXPR_DENSE.

environment linexpr1::get_environment ( ) const

inline

Returns the environment of the expression (with incremented reference count).

const linexpr0 & apron::linexpr1::get_linexpr0 ( ) const

inline

Returns a reference to the underlying linexpr0.

linexpr0 & linexpr1::get_linexpr0 ( )

inline

Returns a modifiable reference to the underlying linexpr0.

ap_linexpr_type_t linexpr1::get_type ( ) const

inline

Gets the type of the linear expression.

Returns: Either AP_LINEXPR_INTLINEAR (coefficients are interval), AP_LINEXPR_QUASILINEAR (coefficients are scalar except the constant one), or AP_LINEXPR_LINEAR (all coefficients are scalar).

bool linexpr1::is_integer ( ) const

inline

Whether the expression only depends on integer variables.

bool linexpr1::is_linear ( ) const

inline

Whether all coefficients are scalar.

bool linexpr1::is_quasilinear ( ) const

inline

Whether all coefficients are scalar, except maybe the constant one.

bool linexpr1::is_real ( ) const

inline

Whether the expression only depends on real variables.

void linexpr1::minimize ( )

inline

Minimizes all coefficients.

In sparse expressions, also remove zero and unused (hole) coefficients to save space.

linexpr1 & linexpr1::operator= ( const linexpr1 & x )

inline

Makes a (deep) copy.

coeff & apron::linexpr1::operator[] ( const var & v )

inline

Returns a (modifiable) reference to the coefficient corresponding to the given variable name.

Exceptions

std::invalid_argument if the variable name is not present in the environment.

const coeff & apron::linexpr1::operator[] ( const var & v ) const

inline

Returns a reference to the coefficient corresponding to the given variable name.

Exceptions

std::invalid_argument if the variable name is not present in the environment.

void linexpr1::print ( FILE * stream = stdout ) const

inline

Prints to a C stream.

size_t linexpr1::size ( ) const

inline

Returns the number of coefficients in the expression.
