SDFloat64.public SDFloat64(String n)
SDFloat64 with name n.n - the name of the variable.public void printDecl(PrintWriter os, String space, boolean print_semi, boolean constrained)
printDecl in class BaseTypeos - The PrintWriter on which to print the
declaration.space - Each line of the declaration will begin with the
characters in this string. Usually used for leading spaces.print_semi - a boolean value indicating whether to print a
semicolon at the end of the declaration.constrained - a boolean value indicating whether to print
the declartion dependent on the projection information. This
is only used by Server side code.DDSpublic void printVal(PrintWriter os, String space, boolean print_decl_p)
printVal() for this type:
All the various versions of printVal() will only
print a value, or a value with declaration, if the variable is
in the projection.
isProject() for a particular variable returns
true then printVal() will print a value
(or a declaration and a value).
isProject() for a particular variable returns
false then printVal() is basically a No-Op.
printVal in class DFloat64os - 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),

setSynthesized in interface ServerMethodsstate - If true then the variable is considered a
synthetic variable and no part of OPeNDAP will ever try to read it from a
file, otherwise if false the variable is considered a

read() method. By default this property is false.isSynthesized(),

This does not send the entire class as the Java Serializable
interface does, rather it sends only the binary data values. Other software
is responsible for sending variable type information (see DDS).
Writes data to a DataOutputStream. This method is used
on the server side of the OPeNDAP client/server connection, and possibly
by GUI clients which need to download OPeNDAP data, manipulate it, and
then re-save it as a binary file.serialize in interface ServerMethodssink - a DataOutputStream to write to.dataset - a String indicated which dataset to read
