Class Base1DBuffer

java.lang.Object

org.python.core.buffer.BaseBuffer

org.python.core.buffer.Base1DBuffer

All Implemented Interfaces:

AutoCloseable, BufferProtocol, PyBUF, PyBuffer

Direct Known Subclasses:

BaseArrayBuffer, BaseNIOBuffer

public abstract class Base1DBuffer
extends BaseBuffer

Base implementation of the Buffer API appropriate to 1-dimensional arrays, of any item size, independent of the storage implementation. The description of BaseBuffer mostly applies.

Method Summary

Modifier and Type	Method and Description
int	getLen() The total number of bytes represented by the view, which will be the product of the elements of the shape array, and the item size in bytes.
boolean	isContiguous(char order) Enquire whether the array is represented contiguously in the backing storage, according to C or Fortran ordering.

Method Detail

getLen

public int getLen()

Description copied from interface: PyBUF

The total number of bytes represented by the view, which will be the product of the elements of the shape array, and the item size in bytes.

Specified by:

getLen in interface PyBUF

Overrides:

getLen in class BaseBuffer

Returns:

the total number of bytes represented.

isContiguous

public boolean isContiguous(char order)

Enquire whether the array is represented contiguously in the backing storage, according to C or Fortran ordering. A one-dimensional contiguous array is both.

Specialised in BaseArrayBuffer to one dimension.

Specified by:

isContiguous in interface PyBUF

Overrides:

isContiguous in class BaseBuffer

Parameters:

order - 'C', 'F' or 'A', as the storage order is C, Fortran or either.

Returns:

true iff the array is stored contiguously in the order specified
