Member Enumeration Documentation

ncType

enum netCDF::NcType::ncType

inherited

List of netCDF types that can be represented.

The enumeration list contains the complete set of netCDF variable types. In addition, the type NC_TYPE is included. This enables the user to instantiate a netCDF type object without explcitly needing to know it precise type.

Enumerator
nc_BYTE	signed 1 byte integer
nc_CHAR	ISO/ASCII character.
nc_SHORT	signed 2 byte integer
nc_INT	signed 4 byte integer
nc_FLOAT	single precision floating point number
nc_DOUBLE	double precision floating point number
nc_UBYTE	unsigned 1 byte int
nc_USHORT	unsigned 2-byte int
nc_UINT	unsigned 4-byte int
nc_INT64	signed 8-byte int
nc_UINT64	unsigned 8-byte int
nc_STRING	string
nc_VLEN	"NcVlen type"
nc_OPAQUE	"NcOpaque type"
nc_ENUM	"NcEnum type"
nc_COMPOUND	"NcCompound type"

Constructor & Destructor Documentation

NcVlenType() [1/4]

NcVlenType::NcVlenType

(

)

Constructor generates a null object.

Definition at line 52 of file ncVlenType.cpp.

NcVlenType() [2/4]

netCDF::NcVlenType::NcVlenType	(	const NcGroup &	grp,
		const std::string &	name
	)

Constructor.

The vlen Type must already exist in the netCDF file. New netCDF vlen types can be added using NcGroup::addNcVlenType();

Parameters

grp	The parent group where this type is defined.
name	Name of new type.

NcVlenType() [3/4]

NcVlenType::NcVlenType

(

const NcType &

ncType

)

Constructor.

Constructs from the base type NcType object. Will throw an exception if the NcType is not the base of a Vlen type.

Parameters

ncType

A Nctype object.

Definition at line 62 of file ncVlenType.cpp.

NcVlenType() [4/4]

NcVlenType::NcVlenType

(

const NcVlenType &

rhs

)

The copy constructor.

Definition at line 45 of file ncVlenType.cpp.

~NcVlenType()

netCDF::NcVlenType::~NcVlenType ( )

inline

Definition at line 49 of file ncVlenType.h.

Member Function Documentation

getBaseType()

NcType NcVlenType::getBaseType

(

)

const

Returns the base type.

Definition at line 70 of file ncVlenType.cpp.

getId()

nc_type netCDF::NcType::getId ( ) const

inlineinherited

The netCDF Id of this type.

Definition at line 88 of file ncType.h.

getName()

string NcType::getName ( ) const

inherited

The name of this type.

For atomic types, the CDL type names are returned. These are as follows:

• NcByte String returned is "byte".
• NcUbyte String returned is "ubyte".
• NcChar String returned is "char".
• NcShort String returned is "short".
• NcUshort String returned is "ushort".
• NcInt String returned is "int".
• NcUint String returned is "uint".
• NcInt64 String returned is "int64".
• NcUint64 String returned is "uint64".
• NcFloat String returned is "float".
• NcDouble String returned is "double".
• NcString String returned is "string".

Definition at line 94 of file ncType.cpp.

getParentGroup()

NcGroup NcType::getParentGroup ( ) const

inherited

Gets parent group.

For an atomic type, returns a Null object.

Definition at line 89 of file ncType.cpp.

getSize()

size_t NcType::getSize ( ) const

inherited

The size in bytes.

This function will work on any type, including atomic and any user defined type, whether compound, opaque, enumeration, or variable length array.

Definition at line 108 of file ncType.cpp.

getTypeClass()

NcType::ncType NcType::getTypeClass ( ) const

inherited

The type class returned as enumeration type.

Valid for all types, whether atomic or user-defined. User-defined types are returned as one of the following enumeration types: nc_VLEN, nc_OPAQUE, nc_ENUM, or nc_COMPOUND.

Definition at line 116 of file ncType.cpp.

getTypeClassName()

string NcType::getTypeClassName ( ) const

inherited

Return a string containing the name of the enumerated type.

(ie one of the following strings: "nc_BYTE", "nc_CHAR", "nc_SHORT", "nc_INT", "nc_FLOAT", "nc_DOUBLE", "nc_UBYTE", "nc_USHORT", "nc_UINT", "nc_INT64", "nc_UINT64", "nc_STRING", "nc_VLEN", "nc_OPAQUE", "nc_ENUM", "nc_COMPOUND"

Definition at line 144 of file ncType.cpp.

isNull()

bool netCDF::NcType::isNull ( ) const

inlineinherited

Returns true if this object is null (i.e.

it has no contents); otherwise returns false.

Definition at line 133 of file ncType.h.

operator!=()

bool NcType::operator!= ( const NcType &  rhs ) const

inherited

!= operator

Definition at line 83 of file ncType.cpp.

operator=() [1/2]

NcVlenType & NcVlenType::operator=

(

const NcType &

rhs

)

Assignment operator.

This assigns from the base type NcType object. Will throw an exception if the NcType is not the base of a Vlen type.

Definition at line 33 of file ncVlenType.cpp.

operator=() [2/2]

NcVlenType & NcVlenType::operator=

(

const NcVlenType &

rhs
