## Fields

### CREATOR

    public static final Creator<TvInputInfo> CREATOR

## Public methods

### canRecord

    public boolean canRecord ()

Returns `true` if this TV input can record TV programs, `false` otherwise.

Returns
`boolean` |

### createSettingsIntent

    public Intent createSettingsIntent ()

This method is deprecated.
Use `createSetupIntent()` instead. Settings activity is deprecated. Use setup activity instead to provide settings.

Returns an intent to start the settings activity for this TV input.

Returns
`Intent` |

### createSetupIntent

    public Intent createSetupIntent ()

Returns an intent to start the setup activity for this TV input.

Returns
`Intent` |

### 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`

### equals

    public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The `equals` method implements an equivalence relation on non-null object references:

- It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.

The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x == y` has the value `true`).

Note that it is generally necessary to override the `hashCode` method whenever this method is overridden, so as to maintain the general contract for the `hashCode` method, which states that equal objects must have equal hash codes.

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

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

### getExtras

    public Bundle getExtras ()

Returns domain-specific extras associated with this TV input.

Returns
`Bundle` |

### getId

    public String getId ()

Returns a unique ID for this TV input. The ID is generated from the package and class name implementing the TV input service.

Returns
`String` |

### getParentId

    public String getParentId ()

Returns the parent input ID.

A TV input may have a parent input if the TV input is actually a logical representation of a device behind the hardware port represented by the parent input. For example, a HDMI CEC logical device, connected to a HDMI port, appears as another TV input. In this case, the parent input of this logical device is the HDMI port.

Applications may group inputs by parent input ID to provide an easier access to inputs sharing the same physical port. In the example of HDMI CEC, logical HDMI CEC devices behind the same HDMI port have the same parent ID, which is the ID representing the port. Thus applications can group the hardware HDMI port and the logical HDMI CEC devices behind it together using this method.

Returns
`String` | the ID of the parent input, if exists. Returns `null` if the parent input is not specified.

### getServiceInfo

    public ServiceInfo getServiceInfo ()

Returns the information of the service that implements this TV input.

Returns
`ServiceInfo` |

### getTunerCount

    public int getTunerCount ()

Returns the number of tuners this TV input has.

This method is valid only for inputs of type `TYPE_TUNER`. For inputs of other types, it returns 0.

Tuners correspond to physical/logical resources that allow reception of TV signal. Having N tuners means that the TV input is capable of receiving N different channels concurrently.

Returns
`int` |

### getType

    public int getType ()

Returns the type of this TV input.

Returns
`int` | Value is `TYPE_TUNER`, `TYPE_OTHER`, `TYPE_COMPOSITE`, `TYPE_SVIDEO`, `TYPE_SCART`, `TYPE_COMPONENT`, `TYPE_VGA`, `TYPE_DVI`, `TYPE_HDMI`, or `TYPE_DISPLAY_PORT`

### 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.

### isHidden

    public boolean isHidden (Context context)

Checks if this TV input is marked hidden by the user in the settings.

Parameters
`context` | `Context`: Supplies a `Context` used to check if this TV input is hidden.

Returns
`boolean` | `true` if the user marked this TV input hidden in settings. `false` otherwise.

### isPassthroughInput

    public boolean isPassthroughInput ()

Returns `true` if this TV input is pass-though which does not have any real channels in TvProvider. `false` otherwise.

Returns
`boolean` |

See also:

- `TvContract.buildChannelUriForPassthroughInput(String)`

### loadCustomLabel

    public CharSequence loadCustomLabel (Context context)

Loads the custom label set by user in settings.

Parameters
`context` | `Context`: Supplies a `Context` used to load the custom label.

Returns
`CharSequence` | a CharSequence containing the TV input's custom label. `null` if there is no custom label.

### loadIcon

    public Drawable loadIcon (Context context)

Loads the user-displayed icon for this TV input.

Parameters
`context` | `Context`: Supplies a `Context` used to load the icon. This value cannot be `null`.

Returns
`Drawable` | a Drawable containing the TV input's icon. If the TV input does not have an icon, application's icon is returned. If it's unavailable too, `null` is returned.

### loadLabel

    public CharSequence loadLabel (Context context)

Loads the user-displayed label for this TV input.

Parameters
`context` | `Context`: Supplies a `Context` used to load the label. This value cannot be `null`.

Returns
`CharSequence` | a CharSequence containing the TV input's label. If the TV input does not have a label, its name is returned.

### 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)

Used to package this object into a `Parcel`.

Parameters
`dest` | `Parcel`: The `Parcel` to be written. This value cannot be `null`.
`flags` | `int`: The flags used for parceling.
