# TextSelection

`public final class TextSelection`

↳ | android.view.textclassifier.TextSelection

Information about where text selection should be.

## Summary

### Nested classes
`class` | `TextSelection.Builder` Builder used to build `TextSelection` objects.
`class` | `TextSelection.Request` A request object for generating TextSelection.

### Inherited constants
From interface `android.os.Parcelable`
`int` | `CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int` | `PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

### Fields
`public static final Creator<TextSelection>` | `CREATOR`

### Public methods
`int` | `describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`float` | `getConfidenceScore(String entity)` Returns the confidence score for the specified entity.
`String` | `getEntity(int index)` Returns the entity at the specified index.
`int` | `getEntityCount()` Returns the number of entities found in the classified text.
`Bundle` | `getExtras()` Returns the extended data.
`String` | `getId()` Returns the id, if one exists, for this object.
`int` | `getSelectionEndIndex()` Returns the end index of the text selection.
`int` | `getSelectionStartIndex()` Returns the start index of the text selection.
`TextClassification` | `getTextClassification()` Returns the text classification result of the suggested selection span.
`String` | `toString()` Returns a string representation of the object.
`void` | `writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

### Inherited methods
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.
From interface `android.os.Parcelable`
`abstract int` | `describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void` | `writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

## Fields

### CREATOR

    public static final Creator<TextSelection> CREATOR

## Public methods

### describeContents

    public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of `writeToParcel(android.os.Parcel, int)`, the return value of this method must include the `CONTENTS_FILE_DESCRIPTOR` bit.

Returns
`int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

### getConfidenceScore

    public float getConfidenceScore (String entity)

Returns the confidence score for the specified entity. The value ranges from 0 (low confidence) to 1 (high confidence). 0 indicates that the entity was not found for the classified text.

Parameters
`entity` | `String`: Value is `TextClassifier.TYPE_UNKNOWN`, `TextClassifier.TYPE_OTHER`, `TextClassifier.TYPE_EMAIL`, `TextClassifier.TYPE_PHONE`, `TextClassifier.TYPE_ADDRESS`, `TextClassifier.TYPE_URL`, `TextClassifier.TYPE_DATE`, `TextClassifier.TYPE_DATE_TIME`, `TextClassifier.TYPE_FLIGHT_NUMBER`, or android.view.textclassifier.TextClassifier.TYPE_DICTIONARY

Returns
`float` | Value is between 0.0 and 1.0 inclusive

### getEntity

    public String getEntity (int index)

Returns the entity at the specified index. Entities are ordered from high confidence to low confidence.

Parameters
`index` | `int`

Returns
`String` | This value cannot be `null`. Value is `TextClassifier.TYPE_UNKNOWN`, `TextClassifier.TYPE_OTHER`, `TextClassifier.TYPE_EMAIL`, `TextClassifier.TYPE_PHONE`, `TextClassifier.TYPE_ADDRESS`, `TextClassifier.TYPE_URL`, `TextClassifier.TYPE_DATE`, `TextClassifier.TYPE_DATE_TIME`, `TextClassifier.TYPE_FLIGHT_NUMBER`, or android.view.textclassifier.TextClassifier.TYPE_DICTIONARY

Throws
`IndexOutOfBoundsException` | if the specified index is out of range.

See also:

- `for the number of entities available.`

### getEntityCount

    public int getEntityCount ()

Returns the number of entities found in the classified text.

Returns
`int` | Value is 0 or greater

### getExtras

    public Bundle getExtras ()

Returns the extended data.

NOTE: Do not modify this bundle.

Returns
`Bundle` | This value cannot be `null`.

### getId

    public String getId ()

Returns the id, if one exists, for this object.

Returns
`String` | This value may be `null`.

### getSelectionEndIndex

    public int getSelectionEndIndex ()

Returns the end index of the text selection.

Returns
`int` |

### getSelectionStartIndex

    public int getSelectionStartIndex ()

Returns the start index of the text selection.

Returns
`int` |

### getTextClassification

    public TextClassification getTextClassification ()

Returns the text classification result of the suggested selection span. Enables the text classification by calling `TextSelection.Request.Builder#setIncludeTextClassification(boolean)`. If the text classifier does not support it, a `null` is returned.

Returns
`TextClassification` |

See also:

- `TextSelection.Request.Builder.setIncludeTextClassification(boolean)`

### toString

    public String toString ()

Returns a string representation of the object. In general, the `toString` method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The `toString` method for class `Object` returns a string consisting of the name of the class of which the object is an instance, the at-sign character ``@`', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

>      getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String` | a string representation of the object.

### writeToParcel

    public void writeToParcel (Parcel dest,
                    int flags)

Flatten this object in to a Parcel.

Parameters
`dest` | `Parcel`: The Parcel in which the object should be written.
`flags` | `int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
