Constructor Detail

DByte

public DByte()

Constructs a new DByte.

DByte

public DByte(String n)

Constructs a new DByte with name n.

Parameters:

n - the name of the variable.

Method Detail

getValue

public final byte getValue()

Get the current value as a byte.

Returns:

the current value.

setValue

public final void setValue(byte newVal)

Set the current value.

Parameters:

newVal - the new value.

newPrimitiveVector

public PrimitiveVector newPrimitiveVector()

Constructs a new BytePrimitiveVector.

Overrides:

newPrimitiveVector in class BaseType

Returns:

a new BytePrimitiveVector.

getTypeName

public String getTypeName()

Returns the OPeNDAP type name of the class instance as a String.

Specified by:

getTypeName in class BaseType

Returns:

the OPeNDAP type name of the class instance as a String.

printVal

public void printVal(PrintWriter os,
            String space,
            boolean print_decl_p)

Prints the value of the variable, with its declaration. This function is primarily intended for debugging OPeNDAP applications and text-based clients such as geturl.

Specified by:

printVal in class BaseType

Parameters:

os - the PrintWriter on which to print the value.

space - this value is passed to the printDecl method, and controls the leading spaces of the output.

print_decl_p - a boolean value controlling whether the variable declaration is printed as well as the value.

BaseType.printVal(PrintWriter, String, boolean)

deserialize

public void deserialize(DataInputStream source,
               ServerVersion sv,
               StatusUI statusUI)
                 throws IOException,
                        EOFException

Reads data from a DataInputStream. This method is only used on the client side of the OPeNDAP client/server connection.

Specified by:

deserialize in interface ClientIO

Parameters:

source - a DataInputStream to read from.

sv - the ServerVersion returned by the server.

statusUI - the StatusUI object to use for GUI updates and user cancellation notification (may be null).

Throws:

EOFException - if EOF is found before the variable is completely deserialized.

IOException - thrown on any other InputStream exception.

See Also:

ClientIO.deserialize(DataInputStream, ServerVersion, StatusUI)

externalize

public void externalize(DataOutputStream sink)
                 throws IOException

Writes data to a DataOutputStream. This method is used primarily by GUI clients which need to download OPeNDAP data, manipulate it, and then re-save it as a binary file.

Specified by:

externalize in interface ClientIO

Parameters:

sink - a DataOutputStream to write to.

Throws:

IOException - thrown on any OutputStream exception.
