Transliterator.Position

封闭类:

Transliterator
```
public static class Transliterator.Position
extends Object
```
Position structure for incremental transliteration. This data structure defines two substrings of the text being transliterated. The first region, [contextStart, contextLimit), defines what characters the transliterator will read as context. The second region, [start, limit), defines what characters will actually be transliterated. The second region should be a subset of the first.
After a transliteration operation, some of the indices in this structure will be modified. See the field descriptions for details.
contextStart <= start <= limit <= contextLimit
Note: All index values in this structure must be at code point boundaries. That is, none of them may occur between two code units of a surrogate pair. If any index does split a surrogate pair, results are unspecified.

  - contextLimit
```
public int contextLimit
```
    Ending index, exclusive, of the context to be considered for a transliteration operation. The transliterator will ignore anything at or after this index. INPUT/OUTPUT parameter: This parameter is updated to reflect changes in the length of the text, but points to the same logical position in the text.
  - contextStart
```
public int contextStart
```
    Beginning index, inclusive, of the context to be considered for a transliteration operation. The transliterator will ignore anything before this index. INPUT/OUTPUT parameter: This parameter is updated by a transliteration operation to reflect the maximum amount of antecontext needed by a transliterator.
  - limit
```
public int limit
```
    Ending index, exclusive, of the text to be transliteratd. INPUT/OUTPUT parameter: This parameter is updated to reflect changes in the length of the text, but points to the same logical position in the text.
  - start
```
public int start
```
    Beginning index, inclusive, of the text to be transliteratd. INPUT/OUTPUT parameter: This parameter is advanced past characters that have already been transliterated by a transliteration operation.

```
public void set(Transliterator.Position pos)
```
    Copies the indices of this position from another.
  - equals
```
public boolean equals(Object obj)
```
    Returns true if this Position is equal to the given object.

    参数:
    
    obj - the reference object with which to compare.
    
    返回:
    
    true if this object is the same as the obj argument; false otherwise.

    Object.hashCode(), HashMap
  - hashCode
```
public int hashCode()
```
    Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.
    The general contract of hashCode is:
    - Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
    - If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
    - It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
    As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

    返回:
    
    a hash code value for this object.

  - toString
```
public String toString()
```
    Returns a string representation of this Position.

    返回:
    
    a string representation of the object.
  - validate
```
public final void validate(int length)
```
    Check all bounds. If they are invalid, throw an exception.
    
    参数:
    
    length - the length of the string this object applies to
    
    抛出:
    
    IllegalArgumentException - if any indices are out of bounds
