SPL standard and specialized toolkits > spl 1.3.0 > spl

The SPL standard toolkit defines several types in the composite operator spl::Sys. These types are used in the config specifications and the built-in functions. Two additional composite operators define types that are used by specific built-in functions: spl::Log and spl::Trace.

Types

• Log.Level: This type, when it is used with the appLog function, species the logging level.
• Sys.CongestionPolicy: CongestionPolicy is used for the config threadedPort clause.
• Sys.Kind: This enum is used when custom metrics are created.
• Sys.LogLevel: The Log level for message logging.
• Sys.OperatorInputPortMetricName: This enum is used when input port metrics are accessed.
• Sys.OperatorOutputPortMetricName: This enum is used when output port metrics are accessed.
• Sys.PEConnection: This tuple type gets connection information for a processing element output port.
• Sys.PEConnections: This type is a list of PEConnection tuple types.
• Sys.PartitionEvictionKind: This enum is used to specify the partition eviction policy for a window.
• Sys.PartitionEvictionSelection: This enum is used to specify the method for evicting a partition from a window.
• Sys.PoolSharingMode: This enum is used with SPL config specifications.
• Sys.Punctuation: Punctuation types returned by currentPunct().
• Sys.TimestampFormat: This enum is used to specify the format used for the toTimestamp built-in function.
• Sys.tm: tm is used for the time and gmtime built-in functions.
• Trace.Level: This type, when it is used with the appTrc function, specifies the tracing level.
