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.

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.

`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, 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 millis)` 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

CREATOR

Added in API level 12

Creator<UsbEndpoint> CREATOR

Public methods

describeContents

Added in API level 12

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.

getAddress

Added in API level 12

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

Added in API level 12

int getAttributes ()

Returns the endpoint's attributes field.

Returns
`int`	the endpoint's attributes

getDirection

Added in API level 12

int getDirection ()

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

Returns
`int`	the endpoint's direction

See also:

getEndpointNumber

Added in API level 12

int getEndpointNumber ()

Extracts the endpoint's endpoint number from its address

Returns
`int`	the endpoint's endpoint number

getInterval

Added in API level 12

int getInterval ()

Returns the endpoint's interval field.

Returns
`int`	the endpoint's interval

getMaxPacketSize

Added in API level 12

int getMaxPacketSize ()

Returns the endpoint's maximum packet size.

Returns
`int`	the endpoint's maximum packet size

getType

Added in API level 12

int getType ()

Returns the endpoint's type. Possible results are:

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

Returns
`int`	the endpoint's type

toString

Added in API level 12

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

Added in API level 12

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_WRITE_RETURN_VALUE`.
