The magic bad value for data.
|
Object |
getMapped()
Returns a single primitive array holding all the pixel data of
this array.
|
OrderedNDShape |
getShape()
Returns an object representing the shape (origin and dimensions)
and pixel sequence of this object.
|
Type |
getType()
Returns the primitive type of the data held by this object.

public boolean canMap()
ArrayImpl
Will only be called after an open call, and before any close call.
public Object getMapped()
ArrayImpl
Will only be called if canMap returns true, and only after an open call and before any close call.
public AccessImpl getAccess() throws IOException
ArrayImpl
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.
