Detailed Description

Iterators to traverse and mutate an expression tree.

As const_iterator, but can be used to modify as well as traverse nodes.

Constructor & Destructor Documentation

texpr0::iterator::iterator ( ap_texpr0_t * l )

inlineprotected

Internal use only.

texpr0::iterator::iterator ( texpr0 & e )

inline

Starts a new iterator at the root of the tree.

texpr0::iterator::iterator ( const iterator & i )

inline

Duplicates the iterator.

Member Function Documentation

texpr0::iterator texpr0::iterator::child ( ) const

inline

Constructs an iterator to the only or left sub-expression of an operator node.

Exceptions

bad_discriminant if the node is not an operator node.

ap_texpr0_t * texpr0::iterator::get_ap_texpr0_t ( )

inline

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

const ap_texpr0_t * apron::texpr0::iterator::get_ap_texpr0_t ( ) const

inline

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

coeff & texpr0::iterator::get_coeff ( ) const

inline

Returns a (modifiable) reference to the coefficient of a constant node.

Exceptions

bad_discriminant if the node is not a constant leaf.

ap_dim_t & texpr0::iterator::get_dim ( ) const

inline

Returns a (modifiable) reference to the dimension of a dimension node.

Exceptions

bad_discriminant if the node is not a dimension node.

ap_texpr_op_t & texpr0::iterator::get_op ( ) const

inline

Returns a (modifiable) reference to the operator kind of an operator node.

Returns: either AP_TEXPR_ADD, AP_TEXPR_SUB, AP_TEXPR_MUL, AP_TEXPR_DIV, AP_TEXPR_MOD, AP_TEXPR_POW AP_TEXPR_NEG, AP_TEXPR_CAST, or AP_TEXPR_SQRT.

Exceptions

bad_discriminant if the node is not an operator node.

ap_texpr_rdir_t & texpr0::iterator::get_rdir ( ) const

inline

Returns a (modifiable) reference to the rounding direction of an operator node.

Returns: either AP_RDIR_NEAREST, AP_RDIR_ZERO, AP_RDIR_UP, AP_RDIR_DOWN, or AP_RDIR_RND.

Exceptions

bad_discriminant if the node is not an operator node.

ap_texpr_rtype_t & texpr0::iterator::get_rtype ( ) const

inline

Returns a (modifiable) reference to the destination type of an operator node.

Returns: either AP_RTYPE_REAL, AP_RTYPE_INT, AP_RTYPE_SINGLE (32-bit), AP_RTYPE_DOUBLE (64-bit), AP_RTYPE_EXTENDED (80-bit), or AP_RTYPE_QUAD (128-bit).

Exceptions

bad_discriminant if the node is not an operator node.

texpr0::iterator texpr0::iterator::left ( ) const

inline

Constructs an iterator to the only of left sub-expression of an operator node.

(Identical to child()).

Exceptions

bad_discriminant if the node is not an operator node.

texpr0::iterator & texpr0::iterator::operator= ( const builder & c )

inline

Replace the sub-expression at the iterator position with a (deep) copy of c.

The iterator is still valid after substitution (it points to the sub-expression copy). However, any iterator in the discarded part becomes invalid.

texpr0::iterator & texpr0::iterator::operator= ( const iterator & i )

inline

Resets the iterator at position i.

texpr0::iterator texpr0::iterator::right ( ) const

inline

Constructs an iterator to the right sub-expression argument of a binary operator node.

Exceptions

bad_discriminant	if the node is not an operator node.
std::out_of_range	if the operator node is not binary.
