public final class StringCharacterIterator
extends Object
implements CharacterIterator
StringCharacterIterator implements the CharacterIterater protocol for a String. The StringCharacterIterator class iterates over the entire String.
Examples:
Traverse the text from start to finish
public void traverseForward(CharacterIterator iter) {
for (char c = iter.first(); c != CharacterIterator.DONE; c = iter.next()) {
processChar(c);
}
}
Traverse the text backwards, from end to start
public void traverseBackward(CharacterIterator iter) {
for (char c = iter.last(); c != CharacterIterator.DONE; c = iter.prev()) {
processChar(c);
}
}
Traverse both forward and backward from a given position in the text.
public void traverseOut(CharacterIterator iter, int pos) {
for (char c = iter.setIndex(pos);
c != CharacterIterator.DONE && notBoundary(c);
c = iter.next()) {}
int end = iter.getIndex();
for (char c = iter.setIndex(pos);
c != CharacterIterator.DONE && notBoundary(c);
c = iter.prev()) {}
int start = iter.getIndex();
processSection(iter.getText.subString(start,end);
}
