Package org.python.core.buffer

## Class Base1DBuffer

- java.lang.Object
- - org.python.core.buffer.BaseBuffer
  - - org.python.core.buffer.Base1DBuffer

- All Implemented Interfaces:
    `java.lang.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.

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method | 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.

    - #### 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
