Class IntegerParser

java.lang.Object

io.spokestack.spokestack.nlu.tensorflow.parsers.IntegerParser

All Implemented Interfaces:

SlotParser

public final class IntegerParser
extends Object
implements SlotParser

This parser converts string representations of integers into integers. These strings may be digits or cardinal or ordinal number names. Strict hyphenation of two-digit numbers is optional.

Only positive values are recognized.

A "range" property is expected in the slot's metadata; this property represents a half-open interval of (start, end] for the range of values the parser should accept. Regardless of the end of the interval, the maximum value that will be parsed is Java's Integer.MAX_VALUE; values greater than this will result in an exception.
