Examples of BufferedDataOutputStream

net.ivoa.util.BufferedDataOutputStream
This class is intended for high performance I/O in scientific applications. It combines the functionality of the BufferedOutputStream and the DataOutputStream as well as more efficient handling of arrays. This minimizes the number of method calls that are required to write data. Informal tests of this method show that it can be as much as 10 times faster than using a DataOutputStream layered on a BufferedOutputStream for writing large arrays. The performance gain on scalars or small arrays will be less but there should probably never be substantial degradation of performance.
Note that there is substantial duplication of code to minimize method invocations. However simple output methods were used where empirical tests seemed to indicate that the simpler method did not cost any time. It seems likely that most of these variations will be washed out across different compilers and users who wish to tune the method for their particular system may wish to compare the the implementation of write(int[], int, int) with write(float[], int, int).
Testing and timing for this class is peformed in the net.ivoa.util.test.BufferedFileTester class.
