Toolkits
A toolkit is a set of SPL artifacts, which are organized into a package. Toolkits make SPL or native functions and primitive or composite operators reusable across different applications.

Installing
Use this information to install, upgrade, and uninstall the Teracloud® Streams product.
Configuring
Create a basic or an enterprise domain which is a single point for configuring and managing common resources, security, and instances.
Administering
Administer the product by using the Teracloud® Streams graphical user interface, APIs, or the streamtool command-line interface.
Developing
Develop stream applications with the Streams Processing Language (SPL), Java, and Python.

- APIs
  Application programming interfaces (APIs) provide functions that simplify applications development.
- Job configuration overlays
  You can specify or change configuration parameters when you use the submitjob or updateoperators operations. The settings control submission constraints, host constraints and locations, and operator status. Parameters are captured and updated in the configuration JSON file. When you change the values in the job configuration overlay file, the changes override any previously set values.
- Commands
  Teracloud® Streams provides a number of commands you use to perform tasks.
- Operator model
  An operator model is an XML document that describes the basic properties of a primitive operator.
- Streams Processing Language (SPL)
  Streams Processing Language (SPL) is a distributed data flow composition language that is used in Teracloud® Streams. SPL has primitive types, program structures, and definitions that are tailored for streaming data.
- Toolkits
  A toolkit is a set of SPL artifacts, which are organized into a package. Toolkits make SPL or native functions and primitive or composite operators reusable across different applications.
  - Specialized toolkit requirements and restrictions
    Several of the specialized toolkits require RPMs that are not required by the Teracloud® Streams product. There are also toolkit restrictions on some platforms.
  - Toolkits
- SPLDOC markup
  You can use SPLDOC markup in the descriptions associated with the SPL artifacts in a toolkit. The spl-make-doc command generates HTML documentation from the marked up artifacts.

Supported ASN.1/SPL Type Combinations

The ASN1Parse operator supports the ASN.1/SPL type combinations that are described in the following list.

Hint: The spl-schema-from-asn1 command line tool uses the SPL types that are marked with *), to create SPL type definitions based on the ASN.1 grammar specification. You can manually replace the generated default SPL types with other supported types.


ASN.1 Type	Supported SPL Types and Fault Behavior
BIT STRING	rstring *) with a ‘0’ or ‘1’ character for each bit
BMPString	blob rstring *)
BOOLEAN	boolean *) rstring with either "true" or "false"
ENUMERATED	Any value in the binary data block that does not fit into the specified integer type, results in a failed conversion. For example, 512 does not fit into a uint8 type that has a range from 0 to 255. enum *), any value in the binary data block that cannot be mapped to an enumeration id, results in a failed conversion int8 int16 int32 int64 rstring that is the name of the enumeration id, except if a value is encountered that has no corresponding enumeration id; in this case, a warning is emitted and the value is presented as integer uint8 uint16 uint32 uint64
GeneralizedTime	rstring with the YYYY-MM-DD HH24:MM:SS format timestamp *)
GeneralString	blob *) rstring that is a hex dump
GraphicString	blob *) rstring that is a hex dump
IA5String	blob rstring *)
INTEGER	Any value in the binary data block that does not fit into the specified integer type, results in a failed conversion. For example, 512 does not fit into a uint8 type that has a range from 0 to 255. int8 int16 int32 int64 *) rstring uint8 uint16 uint32 uint64
ISO646String	blob rstring *)
NULL	boolean *) that is true if the ASN.1 field present, else false
NumericString	blob rstring *)
ObjectDescriptor	blob rstring *)
OBJECT IDENTIFIER	rstring *)
OCTET STRING	blob *) rstring that is a hex dump
PrintableString	blob rstring *)
REAL	float64 *) float32 rstring
RELATIVE-OID	rstring *)
T61String	blob *) rstring that is a hex dump
TeletexString	blob *) rstring that is a hex dump
UniversalString	blob rstring *)
UTCTime	rstring with the YYYY-MM-DD HH24:MM:SS format timestamp *)
UTF8String	blob rstring *)
VideotexString	blob *) rstring that is a hex dump
VisibleString	blob rstring *)

SEQUENCE	tuple<...>
CHOICE	tuple<...>
