Transliterator.Position

public static class Transliterator.Position
extends Object

java.lang.Object
↳	android.icu.text.Transliterator.Position

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.

Summary

Fields
`public int`	`contextLimit` Ending index, exclusive, of the context to be considered for a transliteration operation.

`public int`	`limit` Ending index, exclusive, of the text to be transliteratd.
`public int`	`start` Beginning index, inclusive, of the text to be transliteratd.

Public constructors
`Position()` Constructs a Position object with start, limit, contextStart, and contextLimit all equal to zero.
`Position(int contextStart, int contextLimit, int start)` Constructs a Position object with the given start, contextStart, and contextLimit.
`Position(int contextStart, int contextLimit, int start, int limit)` Constructs a Position object with the given start, limit, contextStart, and contextLimit.
`Position(Transliterator.Position pos)` Constructs a Position object that is a copy of another.

Public methods
`boolean`	`equals(Object obj)` Returns true if this Position is equal to the given object.
`int`	`hashCode()` Returns a hash code value for the object.

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 timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Fields

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 constructors

Position

public Position ()

Constructs a Position object with start, limit, contextStart, and contextLimit all equal to zero.

Position

public Position (int contextStart, 
                int contextLimit, 
                int start)

Constructs a Position object with the given start, contextStart, and contextLimit. The limit is set to the contextLimit.

Parameters
`contextStart`	`int`
`contextLimit`	`int`
`start`	`int`

Position

public Position (int contextStart, 
                int contextLimit, 
                int start, 
                int limit)

Constructs a Position object with the given start, limit, contextStart, and contextLimit.

Parameters
`contextStart`	`int`
`contextLimit`	`int`
`start`	`int`
`limit`	`int`

Position

public Position (Transliterator.Position pos)

Constructs a Position object that is a copy of another.

Parameters
`pos`	`Transliterator.Position`

Public methods

equals

public boolean equals (Object obj)

Returns true if this Position is equal to the given object.

Parameters
`obj`	`Object`: the reference object with which to compare.

Returns
`boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

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 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.)

Returns
`int`	a hash code value for this object.

set

public void set (Transliterator.Position pos)

Copies the indices of this position from another.

Parameters
`pos`	`Transliterator.Position`

toString

public String toString ()

Returns a string representation of this Position.

Returns
`String`	a string representation of the object.

validate

public final void validate (int length)

Check all bounds. If they are invalid, throw an exception.

Parameters
`length`	`int`: the length of the string this object applies to

Throws
`IllegalArgumentException`	if any indices are out of bounds
