Constructor & Destructor Documentation

Int8() [1/3]

libdap::Int8::Int8

(

const string &

n

)

The Int8 constructor accepts the name of the variable to be created.

Note

This type is available in DAP4 only. See http://docs.opendap.org/index.php/DAP4:_Specification_Volume_1#Atomic_Types

Parameters

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

Definition at line 68 of file Int8.cc.

Int8() [2/3]

libdap::Int8::Int8	(	const string &	n,
		const string &	d )

The Int8 server-side constructor accepts the name of the variable and the dataset name from which this instance is created. This is a signed 8-bit integer and was added for DAP4; Byte and UInt8 are unsigned 8-bit integers.

Note

This integer type cannot be used with DAP2; it is only present in DAP4. See http://docs.opendap.org/index.php/DAP4:_Specification_Volume_1#Atomic_Types.

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

deserialize()

void libdap::Int8::deserialize ( D4StreamUnMarshaller & um, DMR & dmr )

override

Definition at line 113 of file Int8.cc.

dump()

void libdap::Int8::dump ( ostream & strm ) const

override

dumps information about this object

Displays the pointer value of this instance and information about this instance.

Parameters

strm	C++ i/o stream to dump the information to

Returns

void

Definition at line 225 of file Int8.cc.

is_dap4_projected()

bool libdap::Int8::is_dap4_projected ( std::vector< std::string > & inventory )

override

When send_p() is true a description of the instance is added to the inventory and true is returned.

Parameters

inventory

is a value-result parameter

Returns

True when send_p() is true, false otherwise

print_val()

void libdap::Int8::print_val ( ostream & out, string space = "", bool print_decl_p = true )

override

Definition at line 124 of file Int8.cc.

ptr_duplicate()

BaseType * libdap::Int8::ptr_duplicate ( )

override

Definition at line 86 of file Int8.cc.

serialize()

void libdap::Int8::serialize ( D4StreamMarshaller & m, DMR & dmr, bool filter = false )

override

Serialize an Int8.

Parameters

m
dmr	Unused
eval	Unused
filter	Unused

Exceptions

Error

is thrown if the value needs to be read and that operation fails.

Definition at line 106 of file Int8.cc.

set_value()

bool libdap::Int8::set_value ( dods_int8 val )

virtual

Definition at line 117 of file Int8.cc.

transform_to_dap2()

std::vector< BaseType * > * libdap::Int8::transform_to_dap2 ( AttrTable * parent_attr_table )

override

DAP4 to DAP2 transform.

Return a DAP2 'copy' of the variable. In this case, since Int8 doesn't have a natural representation in DAP2 we are going to just call it a Byte . Why? Because SIZE.

Parameters

root	The root group that should hold this new variable. Add Group-level stuff here (e.g., D4Dimensions).
container	Add the new variable to this container.

Returns

A pointer to the transformed variable
