Class GestureList

object --+
         |
        GestureList

Manages a list of Gesture objects in the order in which they occured. Represents a sequence of Gestures for the purposes of detecting and filtering that sequence when it occurs on an input device.

Instance Methods

[hide private]

__init__(self, device, action_codes=None, gestures=None, copy_gestures=None)
Stores a reference to the input device.

source code

boolean

__eq__(self, other)
Compares this GestureList to the one provided to see if they represent the same sequence of Gestures on the same device.

source code

integer

__hash__(self)
Builds a hash code for this GestureList based on its Gesture contents by XORing their hash values together.

source code

Gesture

getGestureAt(self, i)
Gets the Gesture stored at the given index.

source code

addGesture(self, gesture)
Adds a Gesture to the end of this GestureList.

source code

integer

getNumGestures(self)
Gets the total number of Gestures currently in this GestureList.

source code

string

asString(self)
Gets a human readable representation of all the Gestures in this GestureList determined by the AEInput device on which they are performed.

source code

AEInput.AEInput

getDevice(self)
Gets the device on which the Gestures in this GestureList are performed.

init(self, device, action_codes=None, gestures=None, copy_gestures=None)
(Constructor)

source code

Stores a reference to the input device. If action codes are specified, wraps them in Gesture objects and stores those objects. If Gestures are specified, stores those objects. If Gestures to copy are given, makes a copy of those objects and stores the copies, not the original references. If none of these is given, creates an empty list to be filled with Gestures later.

Parameters:

device (AEInput.AEInput) - Input device on which this Gesture is performed
action_codes (list of lists of integer) - List of lists of action codes that will be stored in Gesture objects in this GestureList
gestures (list of Gesture) - Gestures that this GestureList should store
copy_gestures (list of Gesture) - Gestures that this GestureList should duplicate and store

Overrides: object.__init__

eq(self, other)
(Equality operator)

source code

Compares this GestureList to the one provided to see if they represent the same sequence of Gestures on the same device. The comparison performed is order dependent since a different sequence of Gestures could represent a different input intention.

Parameters:

other (GestureList) - GestureList to compare to this one

Returns: boolean

Is this GestureList equal to the one provided?

hash(self)
(Hashing function)

source code

Builds a hash code for this GestureList based on its Gesture contents by XORing their hash values together. The hash code is used by an AEInput device to store and retrieve filters from a dictionary.

Returns: integer: Hash code for this GestureList
Overrides: object.__hash__

getGestureAt(self, i)

source code

Gets the Gesture stored at the given index. If the index is invalid, raises IndexError.

Parameters:

i (integer) - Index of the Gesture to retrieve

Returns: Gesture

Gesture retrieved from this GestureList

Raises:

IndexError - When the index is invalid

addGesture(self, gesture)

source code

Adds a Gesture to the end of this GestureList.

Parameters:

gesture (Gesture) - Gesture to add

getNumGestures(self)

source code

Gets the total number of Gestures currently in this GestureList.

Returns: integer: Gesture count

asString(self)

source code

Gets a human readable representation of all the Gestures in this GestureList determined by the AEInput device on which they are performed.

Returns: string: Text representation of all the Gestures in this GestureList

getDevice(self)

source code

Gets the device on which the Gestures in this GestureList are performed.

Returns: AEInput.AEInput: Device on which the Gestures in this GestureList are performed
