protected DelegatingCodepointIterator(CodepointIterator internal)

Method Detail

get

protected char get()

Description copied from class: CodepointIterator

Get the next char

Specified by:

get in class CodepointIterator

get

protected char get(int index)

Description copied from class: CodepointIterator

Get the specified char

Specified by:

get in class CodepointIterator

hasNext

public boolean hasNext()

Description copied from class: CodepointIterator

True if there are codepoints remaining

Specified by:

hasNext in interface Iterator<Codepoint>

Overrides:

hasNext in class CodepointIterator

isHigh

public boolean isHigh(int index)

Description copied from class: CodepointIterator

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

Overrides:

isHigh in class CodepointIterator

isLow

public boolean isLow(int index)

Description copied from class: CodepointIterator

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

Overrides:

isLow in class CodepointIterator

limit

public int limit()

Description copied from class: CodepointIterator

Return the iterator limit

Overrides:

limit in class CodepointIterator

next

public Codepoint next()

Description copied from class: CodepointIterator

Return the next codepoint

Specified by:

next in interface Iterator<Codepoint>

Overrides:

next in class CodepointIterator

nextChars

public char[] nextChars()

Description copied from class: CodepointIterator

Return 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

Description copied from class: CodepointIterator

Peek the specified codepoint

Overrides:

peek in class CodepointIterator

peekChars

public char[] peekChars()

Description copied from class: CodepointIterator

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

Overrides:

peekChars in class CodepointIterator

position

public int position()

Description copied from class: CodepointIterator

Get the iterator position

Overrides:

position in class CodepointIterator

remaining

public int remaining()

Description copied from class: CodepointIterator

Return the remaining iterator size

Overrides:

remaining in class CodepointIterator

position

public void position(int position)

Description copied from class: CodepointIterator

Set the iterator position

Overrides:

position in class CodepointIterator
