Structured line iterator for fixed-length line strings allowing efficient "pipelined" processing. More...
Public Member Functions | |
constructor (string data, hash< auto > spec, __7_ hash< auto > opts) | |
Instantiates the FixedLengthDataIterator object. More... | |
![]() | |
bool | checkTransition (__7_ string from, __7_ string to) |
A verification function to be called for each line. This method can be overridden to achieve a begin-to-end validation of the whole input file. More... | |
constructor (AbstractLineIterator li, hash< auto > spec, __7_ hash< auto > opts) | |
Instantiates the FixedLengthAbstractIterator object. More... | |
__7_ hash< auto > | getValue () |
Returns the current record as a hash. More... | |
bool | identifyRecord (list< auto > rec_rule, string input_line) |
Attempts to identify a single record. | |
string | identifyType (string input_line) |
Identify a fixed-length line type using identifyTypeImpl(), that may be overridden if necessary. More... | |
__7_ string | identifyTypeImpl (string input_line) |
Identify a fixed-length line type, given the raw line string. This method performs a lookup to a precalculated table based on line lengths (see constructor()). In case different criteria are needed, eg. when two line types in a spec have the same length and no unique resolving rule are specified, this method needs to be overridden, and will throw an exception, because the precalculated mapping will be empty. More... | |
bool | next () |
Moves the current line / record position to the next line / record; returns False if there are no more lines to iterate. More... | |
auto | transform (auto value, hash< auto > type) |
parses the input value based on global configuration and the current field definition | |
![]() | |
constructor (hash< auto > m_specs, __7_ hash< auto > m_opts) | |
Creates the object from the record specifications. | |
__7_ hash< string, AbstractDataField > | getRecordType () |
Returns the description of the record type, if any. | |
Additional Inherited Members | |
![]() | |
static __7_ hash< auto > | checkOptions (__7_ hash< auto > opts) |
Validate and prepare global fixed-length options. More... | |
![]() | |
hash | m_resolve_by_length |
hash of type without rule, i.e.potentially conflicting records; key = record length, value = list of no-rule type names | |
![]() | |
const | GlobalOptionMap |
Translates from global options to data provider options. | |
__7_ hash< auto > | m_opts |
Global input or output options. | |
hash< auto > | m_specs |
The record specifications. | |
Structured line iterator for fixed-length line strings allowing efficient "pipelined" processing.
|
inline |
Instantiates the FixedLengthDataIterator object.
data | The input string to process |
spec | Fixed-length line specification; see Specification Hash for more information |
