Detailed Description

template<typename E>
class extended_regular_expression::ere_expression< E >

The one of classes implementing following regular expression grammar:

extended_reg_exp => ere_branch '|' extended_reg_exp | extended_reg_exp
ere_branch => ere_expression ere_branch | ere_expression
ere_expression => ere_expression_and_dups | one_char_or_coll_elem_ere | '^' | '$' | '('extended_reg_exp')'
ere_expression_and_dups => ere_expression_no_dup ere_dups
ere_expression_no_dup => one_char_or_coll_elem_ere | '^' | '$' | '('extended_reg_exp')'
ere_dups => ere_dupl_symbol ere_dups | ere_dupl_symbol
ere_dupl_symbol => '*' | '+' | '?' | '{' number '}] | '{' number ',' '}' | '{' number ',' number '}'
one_char_or_coll_elem_ere => 'all except special chars' | '\' special_chars '.' | bracket_expr
special_chars => '.' | '[' | '\' | '(' | ')' | '*' | '+' | '?' | '{' | '}' | '|' | '^' | '$'
