Functions

fun flattenMap(inMap: Map<String, Map<String, Double>>, catChars: String): LinkedHashMap<String, Double>

Takes the double map and creates a single map by forming unique keys from the double map keys. Use a concatenation string that does not appear within the keys of the inMap and for which a unique key will be formed from the two keys.

makeMap

fun makeMap(keys: Array<String>, values: DoubleArray): LinkedHashMap<String, Double>

Creates a LinkedHashMap to preserve order. If the value is NaN, then the entry is not added to the map.

stringDoubleArrayMapToJson

fun stringDoubleArrayMapToJson(map: Map<String, DoubleArray>): String

Converts a map that has (String, Double) pairs to a JSON string

stringDoubleMapFromJson

fun stringDoubleMapFromJson(string: String): Map<String, Double>

Converts a JSON string representation to a Map with keys that are strings and values that are doubles.

stringDoubleMapToJson

fun stringDoubleMapToJson(map: Map<String, Double>): String

Converts a map that has (String, Double) pairs to a JSON string

unflattenMap

fun unflattenMap(inMap: Map<String, Double>, catChars: Char): LinkedHashMap<String, MutableMap<String, Double>>

Reverses the operation of un-flatten using the provided catChars. Assumes that the catChars will slit the keys of the map into two separate strings that can be used as keys into the returned double map. A duplicate key within the inner map will result in an exception.
