Using Core Functions
Scalar functions that can be applied with Using the DeriveFields Operator to Compute New Fields are contained in the com.pervasive.dataflow.functions package. The functions are grouped into categories. Each category is contained within a single Java class. Each class contains a set of static methods for creating scalar functions.
Each category and its available functions are outlined below. Unless otherwise noted, the equivalent function in RushScript will match the scalar function.
Arithmetic Functions
The Arithmetic category provides functions for doing basic arithmetic functions.
Conditional Functions
The Conditionals category provides functions that apply logic for conditionally selecting input values.
Constant Reference Functions
The ConstantReference category contains two functions: constant and nullValue.
Conversion Functions
The Conversions category provides a set of functions for converting the types of input data values.
Date and Time Functions
The DateTime category provides functions for dealing with date, time, and timestamp values.
Field Reference Functions
The FieldReference category provides functions for accessing named fields within input data. These functions can be used in places where a function is required but a simple field value access is wanted.
Formatting Functions
The Formatting category provides implementations of common formatting functions.
Math Functions
The Math category provides implementations of common math functions.
Predicate Functions
The Predicates category provides implementations of common boolean and logical functions.
Statistics Functions
The Statistics category provides implementations of common statistical functions.
String Functions
The Strings category provides common String manipulation functions.
