Constructor & Destructor Documentation

Float64() [1/3]

libdap::Float64::Float64

(

const string &

n

)

The Float64 constructor requires only the name of the variable to be created. The name may be omitted, which will create a nameless variable. This may be adequate for some applications.

Parameters

n	A string containing the name of the variable to be created.

Definition at line 84 of file Float64.cc.

Float64() [2/3]

libdap::Float64::Float64	(	const string &	n,
		const string &	d )

The Float64 server-side constructor accepts the name of the variable and the dataset name from which this instance is created.

Parameters

n	A string containing the name of the variable to be created.
d	A string containing the name of the dataset from which this variable is created

serialize() [2/2]

void libdap::Float64::serialize ( D4StreamMarshaller & m, DMR & dmr, bool filter = false )

override

Serialize an Int8.

Parameters

m
dmr	Unused
eval	Unused

Exceptions

Error

value()

dods_float64 libdap::Float64::value ( ) const

virtual

Return the value of the Float64 held by this instance. This is more convenient than the general interface provided by buf2val, but its use requires a downcase from BaseType to Float64.

Returns

The dods_float32 value.
