Constructor Detail

DelegatingCodepointIterator

protected DelegatingCodepointIterator(@Nonnull
                                      AbstractCodepointIterator aInternal)

Method Detail

getInternalIterator

@Nonnull
public AbstractCodepointIterator getInternalIterator()

get

protected char get()

get

protected char get(int index)

hasNext

public boolean hasNext()

Specified by:

hasNext in interface ICodepointIterator

Specified by:

hasNext in interface Iterator<Codepoint>

Returns:

true if there are codepoints remaining

lastPosition

public int lastPosition()

Specified by:

lastPosition in interface ICodepointIterator

Returns:

the final index position

isHigh

public boolean isHigh(int index)

Specified by:

isHigh in interface ICodepointIterator

Parameters:

index - index

Returns:

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

isLow

public boolean isLow(int index)

Specified by:

isLow in interface ICodepointIterator

Parameters:

index - index

Returns:

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

limit

public int limit()

Specified by:

limit in interface ICodepointIterator

Returns:

the iterator limit

next

@Nullable
public Codepoint next()

Specified by:

next in interface ICodepointIterator

Specified by:

next in interface Iterator<Codepoint>

Returns:

the next codepoint

nextChars

@Nullable
public char[] nextChars()

Specified by:

nextChars in interface ICodepointIterator

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

peek

@Nullable
public Codepoint peek()

Specified by:

peek in interface ICodepointIterator

Returns:

Peek the next codepoint

peek

@Nullable
public Codepoint peek(int index)

Specified by:

peek in interface ICodepointIterator

Parameters:

index - index

Returns:

Peek the specified codepoint

peekChars

@Nullable
public char[] peekChars()

Specified by:

peekChars in interface ICodepointIterator

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

position

public int position()

Specified by:

position in interface ICodepointIterator

Returns:

the iterator position

remaining

public int remaining()

Specified by:

remaining in interface ICodepointIterator

Returns:

the remaining iterator size

position

public void position(int position)

Description copied from interface: ICodepointIterator

Set the iterator position

Specified by:

position in interface ICodepointIterator

Parameters:

position - new position

remove

public void remove()

Specified by:

remove in interface Iterator<Codepoint>
