sparklyr (version 1.7.8)

jarray: Instantiate a Java array with a specific element type.

Description

Given a list of Java object references, instantiate an Array[T] containing the same list of references, where T is a non-primitive type that is more specific than java.lang.Object.

Usage

jarray(sc, x, element_type)

Arguments

sc

A spark_connection.

x

A list of Java object references.

element_type

A valid Java class name representing the generic type parameter of the Java array to be instantiated. Each element of x must refer to a Java object that is assignable to element_type.

Examples

sc <- spark_connect(master = "spark://HOST:PORT")

string_arr <- jarray(sc, letters, element_type = "java.lang.String")
# string_arr is now a reference to an array of type String[]
