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 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 12

 public static final Creator<UsbEndpoint> CREATOR

Public methods

describeContents

Added in API level 12

 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

Added in API level 12

 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

Added in API level 12

 public int getAttributes ()

Returns the endpoint's attributes field.

Returns
`int`	the endpoint's attributes

getDirection

Added in API level 12

 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

Added in API level 12

 public int getEndpointNumber ()

Extracts the endpoint's endpoint number from its address

Returns
`int`	the endpoint's endpoint number

getInterval

Added in API level 12

 public int getInterval ()

Returns the endpoint's interval field.

Returns
`int`	the endpoint's interval

getMaxPacketSize

Added in API level 12

 public int getMaxPacketSize ()

Returns the endpoint's maximum packet size.

Returns
`int`	the endpoint's maximum packet size

getType

Added in API level 12

 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

Added in API level 12

 public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.

writeToParcel

Added in API level 12

 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. 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 `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
