public interface RangeValueIterator
Interface for enabling iteration over sets of
The result for each iteration is the consecutive range of
Hence value(start) = value(start + 1) = .... = value(start + n) = .... = value(limit - 1). However value(start -1) != value(start) and value(limit) != value(start).
Most implementations will be created by factory methods, such as the character type iterator in UCharacter.getTypeIterator. See example below.
Example of use:RangeValueIterator iterator = UCharacter.getTypeIterator(); RangeValueIterator.Element result = new RangeValueIterator.Element(); while (iterator.next(result)) { System.out.println("Codepoint \\u" + Integer.toHexString(result.start) + " to codepoint \\u" + Integer.toHexString(result.limit - 1) + " has the character type " + result.value); }

Nested Class Summary | |
---|---|
static class | RangeValueIterator.Element
Return result wrapper for com.ibm.icu.util.RangeValueIterator.
|
Method Summary | |
---|---|
boolean | next(RangeValueIterator.Element element) Gets the next maximal result range with a common value and returns true if we are not at the end of the iteration, false otherwise. If the return boolean is a false, the contents of elements will not be updated. |
void | reset()
Resets the iterator to the beginning of the iteration. |
Gets the next maximal result range with a common value and returns true if we are not at the end of the iteration, false otherwise.
If the return boolean is a false, the contents of elements will not be updated.
Parameters: element for storing the result range and value
Returns: true if we are not at the end of the iteration, false otherwise.
