Method Details

[hide private]

init(self, args=`{}`, sourceKey=None, deltaKey=None, value=0.0)
(Constructor)

source code

Parameters:

sourceKey - the feature to be changed
deltaKey - the feature to use in computing the delta
value (float) - the coefficient for that feature
sourceKey,deltaKey (Key)

Overrides: KeyedVector.__init__

instantiate(self, table)

source code

Substitutes values for any abstract references, using the given substitution table

Parameters:

table - dictionary of key-value pairs, where the value will be substituted for any appearance of the given key in a field of this Key object

Returns: KeyedVector

Overrides: KeyedVector.instantiate

(inherited documentation)

instantiateKeys(self, table)

source code

Substitutes values for any abstract references, using the given substitution table

Parameters:

table (dictionary) - dictionary of key-value pairs, where the value will be substituted for any appearance of the given key in a field of this Key object

Overrides: KeyedVector.instantiateKeys

Extracts the distribution from the given XML element

Parameters:

element (Element) - The XML Element object specifying the vector
changeInPlace (boolean) - flag, if True, then modify this vector itself; otherwise, return a new vector

Returns:

the KeyedVector instance

Overrides: KeyedVector.parse
