delegator	back to summary
protected SequenceIndexDelegate delegator A delegate that handles index checking and manipulation for get, set and del operations on this sequence in the form of a "pluggable behaviour". Because different types of sequence exhibit subtly different behaviour, there is scope for subclasses to customise the behaviour with their own extension of `SequenceIndexDelegate`.

PySequence	back to summary
protected PySequence(PyType type, SequenceIndexDelegate behaviour) Construct a PySequence for the given sub-type with custom index behaviour. In practice, restrictions on the construction of inner classes will mean null has to be passed and the actual delegator assigned later. Parameters type:PyType actual (Python) type of sub-class behaviour:SequenceIndexDelegate specific index behaviour (or null)

setslice back to summary

protected void setslice(int start, int stop, int step, PyObject value)

Sets the given range of elements according to Python slice assignment semantics. If the step size is one, it is a simple slice and the operation is equivalent to deleting that slice, then inserting the value at that position, regarding the value as a sequence (if possible) or as a single element if it is not a sequence. If the step size is not one, but start==stop, it is equivalent to insertion at that point. If the step size is not one, and start!=stop, the slice defines a certain number of elements to be replaced, and the value must be a sequence of exactly that many elements (or convertible to such a sequence).

Parameters

start:int: the position of the first element.
stop:int: one more than the position of the last element.
step:int: the step size.
value:PyObject: an object consistent with the slice assignment

sliceLength	back to summary
protected static final int sliceLength(int start, int stop, long step) Make step a long in case adding the start, stop and step together overflows an int.

unsupportedopMessage

Overrides org.python.core.PyObject.unsupportedopMessage.

Return sequence-specific error messages suitable for substitution. {0} is the op name. {1} is the left operand type. {2} is the right operand type.
