Constructor Detail

BinaryReader

public BinaryReader(String name)
             throws IOException

Open the named file.

The first few bytes will be read to verify that the file starts with the appropriate MAGIC_STR characters and that this class can read the format version used by the file.

Parameters:

name - Name of file to be read.

Throws:

IOException - If the file cannot be opened.

BinaryReader

public BinaryReader(File ref)
             throws IOException

Open the referenced file.

The first few bytes will be read to verify that the file starts with the appropriate MAGIC_STR characters and that this class can read the format version used by the file.

Parameters:

ref - File to be read.

Throws:

IOException - If the file cannot be opened.

BinaryReader

public BinaryReader(InputStream stream)
             throws IOException

Prepare to read a binary object from the specified stream.

The first few bytes will be read to verify that the stream starts with the appropriate MAGIC_STR characters and that this class can read the format version used by the file.

Parameters:

stream - Stream to read.

Throws:

IOException - If the file cannot be opened.

BinaryReader

public BinaryReader(RandomAccessFile raf)
             throws IOException

Prepare to read a binary object from the specified stream.

The first few bytes will be read to verify that the stream starts with the appropriate MAGIC_STR characters and that this class can read the format version used by the file.

Parameters:

raf - File to read.

Throws:

IOException - If the file cannot be opened.

BinaryReader

public BinaryReader(ucar.netcdf.RandomAccessFile raf)
             throws IOException

Prepare to read a binary object from the specified stream.

The first few bytes will be read to verify that the stream starts with the appropriate MAGIC_STR characters and that this class can read the format version used by the file.

Parameters:

raf - File to read.

Throws:

IOException - If the file cannot be opened.
