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 timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

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

Added in API level 28

public static final Creator<TextSelection> CREATOR

Public methods

describeContents

Added in API level 28

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(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

Added in API level 26

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

Parameters
`entity`	`String`: Value is one of the following: `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` `TextClassifier.TYPE_OTP` `TextClassifier.TYPE_SMS_RETRIEVER_OTP` `TextClassifier.TYPE_SMS_WEB_OTP`

entity

String: Value is one of the following:

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

getEntity

Added in API level 26

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

Returns
`String`	This value cannot be `null`. Value is one of the following: `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` `TextClassifier.TYPE_OTP` `TextClassifier.TYPE_SMS_RETRIEVER_OTP` `TextClassifier.TYPE_SMS_WEB_OTP`

String

This value cannot be null.
Value is one of the following:

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

See also:

for the number of entities available.

getEntityCount

Added in API level 26

public int getEntityCount ()

Returns the number of entities found in the classified text.

Returns
`int`	Value is 0 or greater

getExtras

Added in API level 29

public Bundle getExtras ()

Returns the extended data.

NOTE: Do not modify this bundle.

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

getId

Added in API level 28

public String getId ()

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

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

getSelectionEndIndex

Added in API level 26

public int getSelectionEndIndex ()

Returns the end index of the text selection.

Returns
`int`

getSelectionStartIndex

Added in API level 26

public int getSelectionStartIndex ()

Returns the start index of the text selection.

Returns
`int`

getTextClassification

Added in API level 31

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

Added in API level 26

public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.

writeToParcel

Added in API level 28

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. This value cannot be `null`.
`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 the following: `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`
