public final class StringCharacterIterator

extends Object

implements CharacterIterator

StringCharacterIterator implements the CharacterIterater protocol for a String. The StringCharacterIterator class iterates over the entire String.

StringCharacterIterator(String text, int pos)
Constructs an iterator with the specified initial index.

StringCharacterIterator(String text, int begin, int end, int pos)
Constructs an iterator over the given range of the given string, with the index set at the specified position.

Constructor Detail

StringCharacterIterator

public StringCharacterIterator(String text)

Constructs an iterator with an initial index of 0.

StringCharacterIterator

public StringCharacterIterator(String text,
                               int pos)

Constructs an iterator with the specified initial index.

Parameters:

text - The String to be iterated over

pos - Initial iterator position

StringCharacterIterator

public StringCharacterIterator(String text,
                               int begin,
                               int end,
                               int pos)

Constructs an iterator over the given range of the given string, with the index set at the specified position.

Parameters:

text - The String to be iterated over

begin - Index of the first character

end - Index of the character following the last character

pos - Initial iterator position

Method Detail

setText

public void setText(String text)

Reset this iterator to point to a new string. This package-visible method is used by other java.text classes that want to avoid allocating new StringCharacterIterator objects every time their setText method is called.

Parameters:

text - The String to be iterated over

first

public char first()

Implements CharacterIterator.first() for String.

Specified by:

first in interface CharacterIterator

last

public char last()

Implements CharacterIterator.last() for String.

Specified by:

last in interface CharacterIterator

See Also:

CharacterIterator.last()

setIndex

public char setIndex(int p)

Implements CharacterIterator.setIndex() for String.

Specified by:

setIndex in interface CharacterIterator

See Also:

CharacterIterator.setIndex(int)

current

public char current()

Implements CharacterIterator.current() for String.

Specified by:

current in interface CharacterIterator

See Also:

CharacterIterator.current()

next

public char next()

Implements CharacterIterator.next() for String.

Specified by:

next in interface CharacterIterator

See Also:

CharacterIterator.next()

previous

public char previous()

Implements CharacterIterator.previous() for String.

Specified by:

previous in interface CharacterIterator

See Also:

CharacterIterator.previous()

getBeginIndex

public int getBeginIndex()

Implements CharacterIterator.getBeginIndex() for String.

Specified by:

getBeginIndex in interface CharacterIterator

public int getEndIndex()

Implements CharacterIterator.getEndIndex() for String.

Specified by:

getEndIndex in interface CharacterIterator

See Also:

CharacterIterator.getEndIndex()

getIndex

public int getIndex()

Implements CharacterIterator.getIndex() for String.

Specified by:

getIndex in interface CharacterIterator

See Also:

CharacterIterator.getIndex()

equals

public boolean equals(Object obj)

Compares the equality of two StringCharacterIterator objects.

Parameters:

obj - the StringCharacterIterator object to be compared with.

Returns:

true if the given obj is the same as this StringCharacterIterator object; false otherwise.

Overrides:

equals in class Object

hashCode

public int hashCode()

Computes a hashcode for this iterator.

Returns:

A hash code

Overrides:

hashCode in class Object

clone

public Object clone()

Creates a copy of this iterator.

Specified by:

clone in interface CharacterIterator

Returns:

A copy of this

Overrides:

clone in class Object
