Method Detail

asGVectorOrNull

public static GVector asGVectorOrNull(Object value)

asGVector

public static GVector asGVector(Object value)

asSequenceOrNull

public static List asSequenceOrNull(Object value)

asIntSequenceOrNull

public static IntSequence asIntSequenceOrNull(Object value)

coerceToSequence

public static List coerceToSequence(Object value)

getAt

public static Object getAt(List seq,
                           int index)

getSize

public static int getSize(Object values)

getIterator

public static Iterator getIterator(Object object)

Get an Iterator for a "sequence-like" object. This handles Iterables, CharSequences, and Java arrays. A CharSequences is treated as a sequence of (20-bit) code-points, not 16-bit char values.

subList

public static Object subList(Object base,
                             int fromIndex,
                             int toIndex)

indirectIndexed

public static List indirectIndexed(List lst,
                                   IntSequence indexes)

drop

public static Object drop(Object base,
                          int count)

drop

public static Object drop(Object base,
                          int fromStart,
                          int fromEnd)

copySimple

public static SimpleVector copySimple(SimpleVector base,
                                      int start,
                                      int end,
                                      boolean writable)

Do a logical substring operation with sharing. Requires base.isVerySimple() || base.isSubRange(). Note also that if base is an FString, the indexes count 16-bit code units.

copy

public static SimpleVector copy(SimpleVector base,
                                int start,
                                int end,
                                boolean writable)

copy

public static SimpleVector copy(List base,
                                Range.IntRange range,
                                boolean writable)

copyInPlaceIsSafe

public static boolean copyInPlaceIsSafe(Object src,
                                        Object dst)

replace

public static void replace(List lst,
                           int fromStart,
                           int fromEnd,
                           List values)

writeUInt

public static void writeUInt(int value,
                             Consumer out)

writeULong

public static void writeULong(long value,
                              Consumer out)
