question: attempt to match the regular expression and line position provided at construction to the physical line . concode_field_sep Pattern pattern concode_elem_sep int startPosition concode_elem_sep int physicalLine concode_field_sep String toString concode_elem_sep String readPhysicalLines
target: boolean function ( int arg0 , int arg1 , FlatFileParser . LineReader arg2 ) { String loc0 = readPhysicalLines ( arg2 , physicalLine ) ; if ( loc0 == null ) return false ; if ( startPosition >= loc0 . length ( ) ) return false ; Matcher loc1 = pattern . loc1 ( loc0 ) ; return loc1 . find ( startPosition ) ; }
