Class CodePointMap.StringIterator

java.lang.Object

org.graalvm.shadowed.com.ibm.icu.util.CodePointMap.StringIterator

Enclosing class:

CodePointMap

public class CodePointMap.StringIterator
extends Object

Iterates over code points of a string and fetches map values. This does not implement java.util.Iterator.

 void onString(CodePointMap map, CharSequence s, int start) {
     CodePointMap.StringIterator iter = map.stringIterator(s, start);
     while (iter.next()) {
         int end = iter.getIndex();  // code point from between start and end
         useValue(s, start, end, iter.getCodePoint(), iter.getValue());
         start = end;
     }
 }
 

This class is not intended for public subclassing.

Method Summary

Modifier and Type	Method and Description
int	getCodePoint()
int	getIndex()
int	getValue()
boolean	next() Reads the next code point, post-increments the string index, and gets a value from the map.
boolean	previous() Reads the previous code point, pre-decrements the string index, and gets a value from the map.
void	reset(CharSequence s, int sIndex) Resets the iterator to a new string and/or a new string index.

Method Detail

reset

public void reset(CharSequence s,
                  int sIndex)

Resets the iterator to a new string and/or a new string index.

Parameters:

s - string to iterate over

sIndex - string index where the iteration will start

next

public boolean next()

Reads the next code point, post-increments the string index, and gets a value from the map. Sets an implementation-defined error value if the code point is an unpaired surrogate.

Returns:

true if the string index was not yet at the end of the string; otherwise the iterator did not advance

previous

public boolean previous()

Reads the previous code point, pre-decrements the string index, and gets a value from the map. Sets an implementation-defined error value if the code point is an unpaired surrogate.

Returns:

true if the string index was not yet at the start of the string; otherwise the iterator did not advance

getIndex

public final int getIndex()

Returns:

the string index

getCodePoint

public final int getCodePoint()

Returns:

the code point

getValue

public final int getValue()

Returns:

the map value, or an implementation-defined error value if the code point is an unpaired surrogate
