Chapter 7 - Basic Types

7.1 - Purpose top

Provide basic building blocks to construct new, more complex user types in the form of Software Entities stored in entity files.

7.2 - Usage top

A <basic-type> can be specified in one of two ways:

<plain-basic-type>

<imported-type>

An <imported-type> is defined as follows:

   <entity-reference>.<field-identifier>

7.3 - Description top

A <plain-basic-type> is one of the type identifiers defined in the following table.

Table 1 - Basic types in Sisendel

Type id Description Notes

bool Boolean value -

enum Enumerated value Enumeration values must be defined in section DEFS

float Floating point number Lower and upper bound of validity range may optionally be defined in section DEFS

function Computational object Function parameters and return value(s) must be defined in section DEFS

int8 Signed 8-bit integer number -

int16 Signed 16-bit integer number -

int32 Signed 32-bit integer number -

int64 Signed 64-bit integer number -

range Range of integer values Lower and upper bound of range must be defined in section DEFS

string String of characters Length of string must be specified, may be dynamic

thing Generic object Can be used as a placeholder for complex or multimedia objects, such as documents, sound files, and videoclips (or smell, taste and tactile files in the future).

time Time value -

uint8 Unsigned 8-bit integer number -

uint16 Unsigned 16-bit integer number -

uint32 Unsigned 32-bit integer number -

uint64 Unsigned 64-bit integer number -

unique_id Unique identifier -

Fields whose type is an <imported-type> allow to centralize and share common field type definitions across two or more Software Entities.

The field identifier of the <imported-type> is the <field-identifier> of a field defined by the entity referred to by the <entity-reference>.

An <optional-cardinality> may be specified for fields of any basic type, except for fields of type function.
