StringCharacterIterator

public final class StringCharacterIterator
extends Object implements CharacterIterator

java.lang.Object

Inherited methods

From class java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

From interface java.text.CharacterIterator

`abstract Object`	`clone()` Create a copy of this iterator
`abstract char`	`current()` Gets the character at the current position (as returned by getIndex()).
`abstract char`	`first()` Sets the position to getBeginIndex() and returns the character at that position.
`abstract int`	`getBeginIndex()` Returns the start index of the text.
`abstract int`	`getEndIndex()` Returns the end index of the text.
`abstract int`	`getIndex()` Returns the current index.
`abstract char`	`last()` Sets the position to getEndIndex()-1 (getEndIndex() if the text is empty) and returns the character at that position.
`abstract char`	`next()` Increments the iterator's index by one and returns the character at the new index.
`abstract char`	`previous()` Decrements the iterator's index by one and returns the character at the new index.
`abstract char`	`setIndex(int position)` Sets the position to the specified position in the text and returns that character.
