Constructor Detail

• ConvertArrayImpl

  public ConvertArrayImpl(NDArray nda,
                          Converter conv)

  Constructs a new ArrayImpl from an underlying NDArray and a supplied converter object.

  Parameters:

  nda - the base NDArray which supplies the pixels to be converted

  conv - a Converter object which operates on the pixels of nda. Its base type (type1) must match the type of nda.

  Throws:

  java.lang.IllegalArgumentException - if conv.getType1() is not equal to nda.getType().

Method Detail

• getType

  public Type getType()

  Description copied from interface: ArrayImpl
  Returns the primitive type of the data held by this object. The return value must not change over the lifetime of the object.

  Specified by:

  getType in interface ArrayImpl

  Overrides:

  getType in class WrapperArrayImpl

  Returns:

  an object representing the type of data held.

• getBadValue

  public java.lang.Number getBadValue()

  Description copied from interface: ArrayImpl
  The magic bad value for data. The returned type should be one of the primitive wrapper types, Byte, Short, Integer, Float, Double as appropriate for the type of this array. It may be null if there is no bad value. The return value must not change over the lifetime of the object.

  Specified by:

  getBadValue in interface ArrayImpl

  Overrides:

  getBadValue in class WrapperArrayImpl

  Returns:

  the bad value

• getAccess

  public AccessImpl getAccess()
                       throws java.io.IOException

  Description copied from interface: ArrayImpl
  Returns an object which can access the pixels of this ArrayImpl. Each call to this method returns a new and independent AccessImpl, with an offset initialised to 0 (the start of the array data).

  This method will only be called after the sole call to open and before the sole call to close.

  This method will only be called more than once if the multipleAccess method returns true.

  It is the responsibility of the caller to close the returned AccessImpl when it is no longer required; this enables resources it may hold to be released.

  Specified by:

  getAccess in interface ArrayImpl

  Overrides:

  getAccess in class WrapperArrayImpl

  Returns:

  an accessor for the pixel data

  Throws:

  java.io.IOException - if there is an IO error
