NAME
XML::Compile::Schema::BuiltInTypes - Define handling of built-in data-types
INHERITANCE
XML::Compile::Schema::BuiltInTypes
is a ExporterSYNOPSIS
# Not for end-users
use XML::Compile::Schema::BuiltInTypes qw/%builtin_types/;DESCRIPTION
Different schema specifications specify different available types, but there is a lot over overlap. The XML::Compile::Schema::Specs module defines the availability, but here the types are implemented.
This implementation certainly does not try to be minimal in size: using the restriction rules and inheritance structure defined in the schema specification would be too slow.
FUNCTIONS
The functions named in this chapter are all used at compile-time by the translator. At that moment, they will be placed in the kind-of opcode tree which will process the data at run-time. You cannot call these functions yourself.
Any
anySimpleType
anyType
Both any*Type built-ins can contain any kind of data. Perl decides how to represent the passed values.
Ungrouped types
boolean
Contains true, false, 1 (is true), or 0 (is false). Unchecked, the actual value is used. Otherwise, 0 and 1 are preferred for the hash value and true and false in XML.
Big Integers
Schema's define integer types which are derived from the decimal type. These values can grow enormously large, and therefore can only be handled correctly using Math::BigInt. When the translator is built with the sloppy_integers option, this will simplify (speed-up) the produced code considerably: all integers then shall be between -2G and +2G.
integer
An integer with an undertermined, but maximally huge number of digits.
long
A little bit shorter than an integer, but still up-to 19 digits.
negativeInteger
nonNegativeInteger
nonPositiveInteger
positiveInteger
unsignedInt
Just too long to fit in Perl's ints.
unsignedLong
Value up-to 20 digits.
Integers
byte
Signed 8-bits value.
int
precissionDecimal
PARTIAL IMPLEMENTATION. Special values INF and NaN not handled.
short
Signed 16-bits value.
unsigned(Short)
unsigned 16-bits value.
unsignedByte
Unsigned 8-bits value.
Floating-point
PARTIAL IMPLEMENTATION: INF, NaN not handled. The float is not limited in size, but mapped on double.
decimal
Decimals are painful: they can be very large, much larger than Perl's internal floats. The value is therefore kept as string. Use Math::BigFloat when you need calculations. You can also pass such object here.
double
A floating-point value.
float
A small floating-point value.
Binary
base64Binary
In the hash, it will be kept as binary data. In XML, it will be base64 encoded.
hexBinary
In the hash, it will be kept as binary data. In XML, it will be hex encoded, two hex digits per byte.
Dates
date
A day, represented in localtime as YYYY-MM-DD or YYYY-MM-DD[-+]HH:mm. When a decimal value is passed, it is interpreted as time value in UTC, and will be formatted as required. When reading, the date string will not be parsed.
dateTime
A moment, represented in localtime as "date T time tz", where date is YYYY-MM-DD, time is HH:MM:SS and optional, and time-zone tz is either -HH:mm, +HH:mm, or Z for UTC.
When a decimal value is passed, it is interpreted as time value in UTC, and will be formatted as required. When reading, the date string will not be parsed.
gDay
Format ---12 or ---12+09:00 (12 days, optional time-zone)
gMonth
Format --09 or --09+07:00 (9 months, optional time-zone)
gMonthDay
Format --09-12 or --09-12+07:00 (9 months 12 days, optional time-zone)
gYear
Format 2006 or 2006+07:00 (year 2006, optional time-zone)
gYearMonth
Format 2006-11 or 2006-11+07:00 (november 2006, optional time-zone)
Duration
dayTimeDuration
Format -PnDTnHnMnS, where optional starting - means negative. The P is obligatory, and the T indicates start of a time part. All other n[DHMS] are optional.
duration
Format -PnYnMnDTnHnMnS, where optional starting - means negative. The P is obligatory, and the T indicates start of a time part. All other n[YMDHMS] are optional.
yearMonthDuration
Format -PnYnMn, where optional starting - means negative. The P is obligatory, the n[YM] are optional.
Strings
ID(, IDREF, IDREFS)
A label, reference to a label, or set of references.
PARTIAL IMPLEMENTATION: the validity of used characters is not checked.
NCName(, ENTITY, ENTITIES)
A name which contains no colons (a non-colonized name).
Name
language
An RFC3066 language indicator.
normalizedString
String where all sequence of white-spaces (including new-lines) are interpreted as one blank. Blanks at beginning and the end of the string are ignored.
string
(Usually utf8) string.
token(, NMTOKEN, NMTOKENS)
URI
NOTATION
NOT IMPLEMENTED, so treated as string.
QName
A qualified type name: a type name with optional prefix. The prefix notation prefix:type will be translated into the {$ns}type notation.
For writers, this translation can only happen when the $ns is also in use on some other place in the message: the name-space declaration can not be added at run-time. In other cases, you will get a run-time error. Play with XML::Compile::Schema::compile(output_namespaces), predefining evenything what may be used, setting the used count to 1.
anyURI
You may pass a string or, for instance, an URI object which will be stringified into an URI. When read, the data will not automatically be translated into an URI object: it may not be used that way.
only in 1999 and 2000/10 schemas
binary
Perl strings can contain any byte, also nul-strings, so can contain any sequence of bits. Limited to byte length.
timeDuration
'Old' name for duration().
uriReference
Probably the same rules as anyURI().
$builtin_types{century} = { period => 'P100Y' } $builtin_types{recurringDate} = { duration => 'P24H', period => 'P1Y' } $builtin_types{recurringDay} = { duration => 'P24H', period => 'P1M' } $builtin_types{timeInstant} = { duration => 'P0Y', period => 'P0Y' } $builtin_types{timePeriod} = { duration => 'P0Y' } $builtin_types{year} = { period => 'P1Y' } $builtin_types{recurringDuration} = ??
