Detailed Description

template<class SymbolType>
class regexp::FormalRegExpStructure< SymbolType >

Represents formal regular expression structure. Regular expression is stored as a tree of FormalRegExpElements.

Template Parameters

SymbolType

used for the terminal alphabet

Constructor & Destructor Documentation

FormalRegExpStructure() [1/4]

template<class SymbolType >

regexp::FormalRegExpStructure< SymbolType >::FormalRegExpStructure

explicit

Creates a new instance of the expression structure. Defaultly created structure is empty expression.

FormalRegExpStructure() [2/4]

template<class SymbolType >

regexp::FormalRegExpStructure< SymbolType >::FormalRegExpStructure ( FormalRegExpElement< SymbolType > &&  structure )

explicit

Creates a new instance of the expression structure. The new instance contains structure as provided by the parameter.

Parameters

structure

the expression structure.

FormalRegExpStructure() [3/4]

template<class SymbolType >

regexp::FormalRegExpStructure< SymbolType >::FormalRegExpStructure ( const FormalRegExpElement< SymbolType > &  structure )

explicit

Creates a new instance of the expression structure. The new instance contains structure as provided by the parameter.

Parameters

structure

the expression structure.

FormalRegExpStructure() [4/4]

template<class SymbolType >

regexp::FormalRegExpStructure< SymbolType >::FormalRegExpStructure ( const UnboundedRegExpStructure< SymbolType > &  other )

explicit

Creates a new instance based on unbounded representation. The new instance contains structure converted to formal representation.

Parameters

other

the structure in unbounded representation
