Method Detail

containsKey

protected boolean containsKey(OptionKey<?> key)

newOptionMap

public static org.graalvm.collections.EconomicMap<OptionKey<?>,Object> newOptionMap()

Creates a new map suitable for using OptionKeys as keys.

getMap

public org.graalvm.collections.UnmodifiableEconomicMap<OptionKey<?>,Object> getMap()

Gets an immutable view of the key/value pairs in this object. Values read from this view should be decoded before being used.

asMap

public static org.graalvm.collections.EconomicMap<OptionKey<?>,Object> asMap(OptionKey<?> key1,
                                                                             Object value1,
                                                                             Object... extraPairs)

Parameters:

key1 - first key in map

value1 - first value in map

extraPairs - key/value pairs of the form [key1, value1, key2, value2, ...]

Returns:

a map containing the key/value pairs as entries

initMap

protected static void initMap(org.graalvm.collections.EconomicMap<OptionKey<?>,Object> map,
                              org.graalvm.collections.UnmodifiableEconomicMap<OptionKey<?>,Object> values)

get

protected <T> T get(OptionKey<T> key)

get

protected static <T> T get(org.graalvm.collections.UnmodifiableEconomicMap<OptionKey<?>,Object> values,
                           OptionKey<T> key)

encodeNull

protected static Object encodeNull(Object value)

decodeNull

public static Object decodeNull(Object value)

Decodes a value that may be the sentinel value for null in a map.

toString

public String toString()

Overrides:

toString in class Object

toString

public static String toString(org.graalvm.collections.UnmodifiableEconomicMap<OptionKey<?>,Object> values)

printHelp

public void printHelp(Iterable<OptionDescriptors> loader,
                      PrintStream out,
                      String namePrefix)

Prints a help message to out describing all options available via loader. The key/value for each option is separated by := if the option has an entry in this object otherwise = is used as the separator.

Parameters:

loader -

out -

namePrefix -
