Class OptionsParser

java.lang.Object

org.graalvm.compiler.options.OptionsParser

public class OptionsParser
extends Object

This class contains methods for parsing Graal options and matching them against a set of OptionDescriptors. The OptionDescriptors are loaded via a ServiceLoader.

Method Detail

getOptionsLoader

public static Iterable<OptionDescriptors> getOptionsLoader()

Gets an iterable of available OptionDescriptors.

setCachedOptionDescriptors

public static void setCachedOptionDescriptors(List<OptionDescriptors> list)

parseOptions

public static void parseOptions(org.graalvm.collections.EconomicMap<String,String> optionSettings,
                                org.graalvm.collections.EconomicMap<OptionKey<?>,Object> values,
                                Iterable<OptionDescriptors> loader)

Parses a map representing assignments of values to options.

Parameters:

optionSettings - option settings (i.e., assignments of values to options)

values - the object in which to store the parsed values

loader - source of the available OptionDescriptors

Throws:

IllegalArgumentException - if there's a problem parsing option

parseOptionSettingTo

public static void parseOptionSettingTo(String optionSetting,
                                        org.graalvm.collections.EconomicMap<String,String> dst)

Parses a given option setting string and adds the parsed key and value dst.

Parameters:

optionSetting - a string matching the pattern <name>=<value>

parseOption

public static void parseOption(String name,
                               Object uncheckedValue,
                               org.graalvm.collections.EconomicMap<OptionKey<?>,Object> values,
                               Iterable<OptionDescriptors> loader)

Parses a given option name and value.

Parameters:

name - the option name

uncheckedValue - the unchecked value for the option

values - the object in which to store the parsed option and value

loader - source of the available OptionDescriptors

Throws:

IllegalArgumentException - if there's a problem parsing option

parseOptionValue

public static Object parseOptionValue(OptionDescriptor desc,
                                      Object uncheckedValue)

Parses a given option value with a known descriptor.

stringSimilarity

public static float stringSimilarity(String str1,
                                     String str2)

Compute string similarity based on Dice's coefficient. Ported from str_similar() in globals.cpp.

collectFuzzyMatches

public static boolean collectFuzzyMatches(Iterable<OptionDescriptor> toSearch,
                                          String name,
                                          Collection<OptionDescriptor> matches)

Collects the set of options that fuzzy match a given option name. String similarity for fuzzy matching is based on Dice's coefficient.

Parameters:

toSearch - the set of option descriptors to search

name - the option name to search for

matches - the collection to which fuzzy matches of name will be added

Returns:

whether any fuzzy matches were found
