Values |
| NAME |
STRING |
No |
|
| SHORTDESC |
STRING |
Yes |
|
| OVERRIDE |
STRING |
Yes |
|
This attribute, if used, denotes the name to be used to denote
the field in the host language at hand. This serves essentially when
the field name conflicts with the host language's reserved words.
|
| INDICATOR |
STRING |
Yes |
|
This attribute, if used, must refer to a boolean field
defined in the enclosing element, which will be marked as TRUE
whenever the field receives a value as the result of
parsing.
|
| TYPE |
|
Yes |
INTEGER; STRING; PCHAR; REAL; ANY; BOOLEAN |
Specifies the predefined type (string, integer, etc.)
if relevant. In some cases, the attribute's type
is not one of these predefined types, and this
attribute is then omitted
|
| REFTYPE |
STRING |
Yes |
|
When an element refers to another element,
the REFTYPE attribute must be used to indicate
the type of this included element.
|
| ENUMTYPE |
STRING |
Yes |
|
When a field is denoted by an enumerated type,
ENUMTYPE holds the name of the enumeration
which must be defined within the same meta-definition file.
|
| ARRAYSIZE |
INTEGER |
Yes |
|
When a field contains a fixed-size
array of instances denoted
by another element, ARRAYSIZE can be used to
indicate the number of elements that can be stored
in the array. If this attribute is not used, a default
value for the system is used. If no such system-wide default
value is specified, a constant value is used, depending
on the target language at hand. If the field is not marked as
being an array (using the MODE attribute),
this attribute, if specified, is ignored.
|
| REGEXP |
STRING |
Yes |
|
ARRAYSIZE can be used to
specify a schema-like regular expression
which will checked against values for the
field at hand at parse time.
This feature is still under development, and might not
be available for all code generators.
