Class BufferDecoder

java.lang.Object

nom.tam.util.InputDecoder

nom.tam.util.FitsDecoder

nom.tam.util.BufferDecoder

@Deprecated
public abstract class BufferDecoder
extends FitsDecoder

Deprecated.

Use FitsDecoder instead which provides a similar function but in a more consistent way and with a less misleading name. This is a rusty rail implementation for of an older abandoned class only, unsafe for general use. For reading non-FITS encoding you may also use InputDecoder as a base for implementing efficient custom decoding of binary inputs in general.

readArrayFully, readImage

Modifier and Type	Method	Description
void	readArrayFully(Object o)	Based on InputDecoder.readArray(Object), but guaranteeing a complete read of the supplied object or else an EOFException is thrown.
void	readImage(Object o)	Like InputDecoder.readArrayFully(Object) but strictly for numerical types only.

Constructor Details

BufferDecoder

@Deprecated
public BufferDecoder(BufferPointer p)

Deprecated.

Instantiates a new decoder for FITS data types.

Parameters:

p - Unused, but the position and length fields are set/reset as to pretend that half of the buffer is perpetually available for reading. However, at no point will there be any data actually in the buffer of this object, and you should by all means avoid directly loading data from the stream into this dead-end buffer, other than the hopefully untiggered existing implementation of checkBuffer(int) (and it's safest if you don't override or ever call checkBuffer(int) from your code!).
