◆ constructor()

Mapper::Mapper::constructor ( hash< auto >  mapv,
*hash< auto >  opts 
)

builds the object based on a hash providing field mappings, data constraints, and optionally custom mapping logic

Example:
const DataMap = (
# output field: "id" mapper from the "Id" element of any "^attributes^" hash in the input record
"id": "^attributes^.Id",
# output field: "name": maps from an input field with the same name (no translations are made)
"name": True,
# output field: "explicit_count": maps from the input "Count" field, if any value is present then it is converted to an integer
"explicit_count": ("type": "int", "name": "Count"),
# output field: "implicit_count": runs the given code on the input record and retuns the result, the code returns the number of "Products" sub-records
"implicit_count": int sub (any ignored, hash rec) { return rec.Products.size(); },
# output field: "order_date": converts the "OrderDate" string input field to a date in the specified format
"order_date": ("name": "OrderDate", "date_format": "DD.MM.YYYY HH:mm:SS.us"),
);
Mapper mapv(DataMap);
Parameters
mapva hash providing field mappings; each hash key is the name of the output field; each value is either True (meaning no translations are done; the data is copied 1:1) or a hash describing the mapping; see Mapper Specification Format for detailed documentation for this option
optsan optional hash of options for the mapper; see Mapper Options for a description of valid mapper options
Exceptions

this method applies the mapData() method to all input records and returns the resulting list

Parameters
recsa hash of lists of input records
Returns
the mapped data as a list of output records
Exceptions
MISSING-INPUTa field marked mandatory is missing
STRING-TOO-LONGa field value exceeds the maximum value and the 'trunc' key is not set

INVALID-NUMBERthe field is marked as numeric but the input value contains non-numeric data

◆ mapAuto()

auto Mapper::Mapper::mapAuto ( auto  recs)

maps all input record(s) automatically and returns the mapped data

this method applies the mapAll() method if the input records are given as list and the mapBulk() method if the input is a hash of lists. For a simple hash (one record) it calls the mapData() method.

If NOTHING is passed, then NOTHING is returned with no mapping performed

Parameters
recsinput records (one record or more), can be represented by list or hash
Returns
the mapped data as of output records (type depends on the given records' type)
Exceptions
MISSING-INPUTa field marked mandatory is missing

Mapper 1.5.2

◆ mapBulk()

*hash<auto> Mapper::Mapper::mapBulk ( hash< auto >  rec,

maps a set of records in hash of lists format; returns mapped data in a hash of lists format

Example:
hash<auto> output = mapper.mapBulk(h);
Parameters
recthe input record or record set in case a hash of lists is passed
crecan optional simple hash of data to be added to each input row before mapping
Returns
returns a hash of lists of mapped data
Note
  • using a hash of lists in rec; note that this provides very high performance when used with data provider output that support bulk write operations
  • in case a hash of empty lists is passed, Qore::NOTHING is returned
  • 'crec' does not affect the number of output lines; in particular, if 'rec' is a batch with N rows of a column C and 'crec = {"C": "mystring"}' then the output will be as if there was 'N' rows with C = "mystring" on the input.

Parameters
recthe record to translate

◆ mapFieldIntern()

nothing Mapper::Mapper::mapFieldIntern ( reference< hash< auto >>  h,
string  key,
hash< auto >  rec,
bool  do_list,
int  list_size 
)
private

maps a single field to the target

Performs the actual mapping

Parameters
hthe hash to be updated with the mapped key/value pair; Depending on the mapper specification and the input, it can contain a bulk record (hash of lists) or a hash of both list and non-list keys (these are considered a "constants" in the output record.
keythe column name (hash key) to be mapped (target field)
recinput record - either single record of hash of lists (batch); to increase performance, the input type (single record vs. batch) is determined by the do_list parameter. In case of bulk input, all the lists are supposed to have the same length list_size
do_list- whether the input record rec is single record or bulk format (hash of lists)
list_size- size of the lists in case the input is in bulk format (all lists must have the same length, asserted inside the method).
Note
it is assumed that list_size > 0 whenever do_list is Qore::True
if do_list == Qore::True, the 'rec' can contain a mix of lists and non-list values - the non-list values are used as constants in the mapping - as if expanded to lists with all values identical.

◆ optionKeys()

returns a list of valid constructor options for this class (can be overridden in subclasses)

Returns
a list of valid constructor options for this class (can be overridden in subclasses)

See also
getCount()
