Method Detail

hasNext

boolean hasNext()

Specified by:

hasNext in interface Iterator<Codepoint>

Returns:

true if there are codepoints remaining

lastPosition

@CheckForSigned
int lastPosition()

Returns:

the final index position

nextChars

@Nullable
char[] nextChars()

Returns:

the next chars. If the codepoint is not supplemental, the char array will have a single member. If the codepoint is supplemental, the char array will have two members, representing the high and low surrogate chars

peekChars

@Nullable
char[] peekChars()

Returns:

Peek the next chars in the iterator. If the codepoint is not supplemental, the char array will have a single member. If the codepoint is supplemental, the char array will have two members, representing the high and low surrogate chars

next

@Nullable
Codepoint next()

Specified by:

next in interface Iterator<Codepoint>

Returns:

the next codepoint

peek

@Nullable
Codepoint peek()

Returns:

Peek the next codepoint

peek

@Nullable
Codepoint peek(@Nonnegative
                      int index)

Returns:

Peek the specified codepoint

position

void position(@Nonnegative
            int n)

Set the iterator position

position

@Nonnegative
int position()

Returns:

the iterator position

limit

@Nonnegative
int limit()

Returns:

the iterator limit

remaining

@Nonnegative
int remaining()

Returns:

the remaining iterator size

isHigh

boolean isHigh(@Nonnegative
             int index)

Returns:

true if the char at the specified index is a high surrogate

isLow

boolean isLow(@Nonnegative
            int index)

Returns:

true if the char at the specified index is a low surrogate

restrict

@Nonnull
CodepointIteratorRestricted restrict(@Nonnull
                                           ICodepointFilter aFilter)

restrict

@Nonnull

                                           ICodepointFilter aFilter,
                                           boolean bScanning)

restrict

@Nonnull
CodepointIteratorRestricted restrict(@Nonnull
                                           ICodepointFilter aFilter,
                                           boolean bScanning,
                                           boolean bInvert)
