Member Function Documentation

getStart()

int CDPL.Math.Slice.getStart

(

)

Returns

getStride()

int CDPL.Math.Slice.getStride

(

)

Returns

getSize()

int CDPL.Math.Slice.getSize

(

)

Returns

isEmpty()

bool CDPL.Math.Slice.isEmpty

(

)

Returns

getIndex()

int CDPL.Math.Slice.getIndex

(

int

i

)

Parameters

i

Returns

assign()

ast.Slice CDPL.Math.Slice.assign

(

ast.Slice

s

)

Replaces the current state of self with a copy of the state of the Slice instance s.

Parameters

s	The Slice instance to copy.

Returns

self

swap()

None CDPL.Math.Slice.swap

(

ast.Slice

s

)

Parameters

s

getObjectID()

int CDPL.Math.Slice.getObjectID

(

)

Returns the numeric identifier (ID) of the wrapped C++ class instance.

Different Python Slice instances may reference the same underlying C++ class instance. The commonly used Python expression a is not b thus cannot tell reliably whether the two Slice instances a and b reference different C++ objects. The numeric identifier returned by this method allows to correctly implement such an identity test via the simple expression a.getObjectID() != b.getObjectID().

Returns

The numeric ID of the internally referenced C++ class instance.

__eq__()

bool CDPL.Math.Slice.__eq__

(

ast.Slice

s

)

Returns the result of the comparison operation self == s.

Parameters

s	The Slice instance to be compared with.

Returns

The result of the comparison operation.

__ne__()

bool CDPL.Math.Slice.__ne__

(

ast.Slice

s

)

Returns the result of the comparison operation self != s.

Parameters

s	The Slice instance to be compared with.

Returns

The result of the comparison operation.

__call__()

int CDPL.Math.Slice.__call__

(

int

i

)

Parameters

i

Returns

__getitem__()

int CDPL.Math.Slice.__getitem__

(

int

i

)

Parameters

i
