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 Details

    • 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
