Available Data Types
Odysseus provides a wide range of data types for your processing.
Numeric Types
Double
A doubleprecision 64bit IEEE 754 floating point.
Float
A singleprecision 32bit IEEE 754 floating point.
Long
An 64bit 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 32bit signed two's complement integer. Permissible values are 2,147,483,648 to 2,147,483,647 (inclusive).
Short
An 16bit signed two's complement integer. Permissible values are 32,768 to 32,767 (inclusive).
Byte
An 8bit signed two's complement integer. Permissible values are 128 to 127 (inclusive).
Char
A single 16bit 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 ~2^{31} Unicode characters.
Date and Time Types
Date
Timestamp
Complex Types
Matrix
A nxm matrix consisting of doubleprecision 64bit IEEE 754 floating point numbers.
Vector
A vector consisting of doubleprecision 64bit 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.
