Available Data Types

Odysseus provides a wide range of data types for your processing.

Numeric Types

Double

A double-precision 64-bit IEEE 754 floating point.

Float

A single-precision 32-bit IEEE 754 floating point.

Long

An 64-bit signed two's complement integer. Permissible values are -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 (inclusive).

Integer

An 32-bit signed two's complement integer. Permissible values are -2,147,483,648 to 2,147,483,647 (inclusive).

Short

An 16-bit signed two's complement integer. Permissible values are -32,768 to 32,767 (inclusive).

Byte

An 8-bit signed two's complement integer. Permissible values are -128 to 127 (inclusive).

Char

A single 16-bit Unicode character. Permissible values are '\u0000' (or 0) to '\uffff' (or 65,535 inclusive).

Boolean

A boolean with the two possible values: true and false.

String Types

String

A sequence of characters. A string can contain up to ~2³¹ Unicode characters.

Date and Time Types

Date

Timestamp

Complex Types

Matrix

A nxm matrix consisting of double-precision 64-bit IEEE 754 floating point numbers.

Vector

A vector consisting of double-precision 64-bit IEEE 754 floating point numbers.

List

A list of objects.

The type of objects in the list has to be defined in the schema definition [['timestamp.unixtimestamp', 'List(Integer)']] and can be accessed in expressions: 'timestamp.unixtimestamp[0] = 1162304033'

Optional Data Types

The following data types are not part of the Odysseus Core and may be restricted.

Spatial Data Types (Spatial Feature)

The spatial data types are based on the "Well-known text" (WKA) format.

SpatialGeometry

A spatial geometry

SpatialGeometryCollection

A spatial geometry collection

SpatialCoordinate

A spatial coordinate with attributes x, y, and z.

SpatialCoordinateSequence

A spatial coordinate sequence

SpatialPolarCoordinate

A spatial polar coordinate with attributes r, and a

SpatialPoint

A spatial point width attributes coordinate and srid.

An example for a data input in this format could be:

POINT(7.129585 53.648660);SRID=4326

or just

POINT(7.129585 53.648660)

SpatialMultiPoint

A spatial multi point.

SpatialLineString

A spatial line string with attributes points and srid.
