UsbEndpoint

public class UsbEndpoint
extends Object implements Parcelable

java.lang.Object
↳	android.hardware.usb.UsbEndpoint

A class representing an endpoint on a UsbInterface. Endpoints are the channels for sending and receiving data over USB. Typically bulk endpoints are used for sending non-trivial amounts of data. Interrupt endpoints are used for sending small amounts of data, typically events, separately from the main data streams. The endpoint zero is a special endpoint for control messages sent from the host to device. Isochronous endpoints are currently unsupported.

Summary

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<UsbEndpoint>`	`CREATOR`

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`int`	`getAddress()` Returns the endpoint's address field.
`int`	`getAttributes()` Returns the endpoint's attributes field.
`int`	`getDirection()` Returns the endpoint's direction.
`int`	`getEndpointNumber()` Extracts the endpoint's endpoint number from its address
`int`	`getInterval()` Returns the endpoint's interval field.
`int`	`getMaxPacketSize()` Returns the endpoint's maximum packet size.
`int`	`getType()` Returns the endpoint's type.
`String`	`toString()` Returns a string representation of the object.
`void`	`writeToParcel(Parcel parcel, 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<UsbEndpoint> 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`

getAddress

public int getAddress ()

Returns the endpoint's address field. The address is a bitfield containing both the endpoint number as well as the data direction of the endpoint. the endpoint number and direction can also be accessed via getEndpointNumber() and getDirection().

Returns
`int`	the endpoint's address

getAttributes

public int getAttributes ()

Returns the endpoint's attributes field.

Returns
`int`	the endpoint's attributes

getDirection

public int getDirection ()

Returns the endpoint's direction. Returns UsbConstants#USB_DIR_OUT if the direction is host to device, and UsbConstants#USB_DIR_IN if the direction is device to host.

Returns
`int`	the endpoint's direction

See also:

getEndpointNumber

public int getEndpointNumber ()

Extracts the endpoint's endpoint number from its address

Returns
`int`	the endpoint's endpoint number

getInterval

public int getInterval ()

Returns the endpoint's interval field.

Returns
`int`	the endpoint's interval

getMaxPacketSize

public int getMaxPacketSize ()

Returns the endpoint's maximum packet size.

Returns
`int`	the endpoint's maximum packet size

getType

public int getType ()

Returns the endpoint's type. Possible results are:

UsbConstants#USB_ENDPOINT_XFER_CONTROL (endpoint zero)
UsbConstants#USB_ENDPOINT_XFER_ISOC (isochronous endpoint)
UsbConstants#USB_ENDPOINT_XFER_BULK (bulk endpoint)
UsbConstants#USB_ENDPOINT_XFER_INT (interrupt endpoint)

Returns
`int`	the endpoint's type

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 parcel, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`parcel`	`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
