RemoteAccessorImpl is a UnicastRemoteObject (RMI service) which implements ucar.multiarray.RemoteAccessor using the proxy pattern. Accessor methods are forwarded to the adaptee and adaptee exceptions are wrapped in java.rmi.ServerException.

public MultiArray copyout(int[] origin, int[] shape) throws java.rmi.RemoteException
Accessor
It is easier to implement than to specify :-).
The main reason to implement this instead of using the equivalent proxy is for remote or file access.
assert(origin[ii] + shape[ii] <= lengths[ii]);
copyout
in interface RemoteAccessor
ucar.multiarray.Accessor
origin
- int array specifying the starting index.shape
- int array specifying the extents in each
dimension. This becomes the shape of the return.public void copyin(int[] origin, MultiArray source) throws java.rmi.RemoteException
Accessor
Hopefully this member can be optimized in various situations.
assert(origin[ii] + (source.getLengths())[ii]
<= (getLengths())[ii]);

in interface RemoteAccessor
ucar.multiarray.Accessor
origin
- int array specifying the starting index.source
- MultiArray with the same componentType as
this and shape smaller than
this.getLengths() - origin
public java.lang.Object toArray() throws java.rmi.RemoteException
Accessor
This method acts as bridge between array-based and MultiArray-based APIs.
This method is functionally equivalent to
Object anArray = Array.newInstance(getComponentType(), 1); int [] origin = new int[getRank()] int [] shape = getDimensions(); return toArray(anArray, origin, shape);
toArray
in interface RemoteAccessor
ucar.multiarray.Accessor
public java.lang.Object toArray(java.lang.Object dst, int[] origin, int[] shape) throws java.rmi.RemoteException
Accessor
The anArray argument should be an array. If it is large enough to contain the output, it is used and no new storage is allocated. Otherwise, new storage is allocated with the same component type as the argument, and the data is copied into it.
This method acts as bridge between array-based and MultiArray-based APIs.
This method is similar to copyout(origin, shape).toArray(), but avoids a copy operation and (potentially) an allocation.
NOTE: Implementation of type conversion is deferred until
JDK 1.2. Currently, the componentType of anArray
must be the same as this
