Detailed Description

General Attribute class.

Constructor & Destructor Documentation

◆ Attribute() [1/2]

DD::Image::Attribute::Attribute ( const Attribute &  src)
inline

Copy constructor.

◆ Attribute() [2/2]

Attribute::Attribute ( const char *  name,
AttribType  type,
size_t  size = 0 
)

Basic constructor requires a name and type. Size is defaulted to 0.

Member Function Documentation

◆ operator=()

Attribute & Attribute::operator= ( const Attribute &  b)

Assignment operator. Empty then copy all data from 'b' into this.

References DD::Image::FLOAT_ATTRIB, DD::Image::INT_ATTRIB, DD::Image::MATRIX3_ATTRIB, DD::Image::MATRIX4_ATTRIB, name_, DD::Image::NORMAL_ATTRIB, DD::Image::POINTER_ATTRIB, DD::Image::STD_STRING_ATTRIB, DD::Image::STRING_ATTRIB, type_, DD::Image::VECTOR2_ATTRIB, DD::Image::VECTOR3_ATTRIB, and DD::Image::VECTOR4_ATTRIB.

◆ copy() [1/2]

void Attribute::copy ( int  dest,
const Attribute &  b,
int  b_start 
)

Destructively copy a single item from 'b_start' to 'dest'.

References copy().

Referenced by copy().

◆ copy() [2/2]

void Attribute::copy ( int  dest,
const Attribute &  b,
int  b_start,
int  b_end 
)

Destructively copy a range of items from 'b' to a range beginning at 'dest'.

◆ append() [1/2]

bool Attribute::append ( const Attribute &  b,
int  b_start 
)

Appends data elements from a same type Attribute onto the end of this one. Fails if both types are not the same.

References append().

Referenced by append().

◆ append() [2/2]

bool Attribute::append ( const Attribute &  b,
int  b_start,
int  b_end 
)

Appends a range of elements from a same type Attribute onto the end of this one. Fails if both types are not the same.

References add(), array(), bytes(), size(), and type_.

◆ size()

unsigned Attribute::size ( ) const

Number of data elements in list.

References DD::Image::FLOAT_ATTRIB, DD::Image::INT_ATTRIB, DD::Image::INVALID_ATTRIB, DD::Image::MATRIX3_ATTRIB, DD::Image::MATRIX4_ATTRIB, DD::Image::NORMAL_ATTRIB, DD::Image::POINTER_ATTRIB, DD::Image::STD_STRING_ATTRIB, DD::Image::STRING_ATTRIB, type_, DD::Image::VECTOR2_ATTRIB, DD::Image::VECTOR3_ATTRIB, and DD::Image::VECTOR4_ATTRIB.

Referenced by add(), DD::Image::GeometryList::add_primitive(), append(), Attribute(), copy(), DD::Image::AttribContext::copy_to_channels(), DD::Image::GeoOp::evaluate_transform(), print_info(), print_value(), reserve(), and resize().

◆ add()

void Attribute::add ( unsigned  n = 1)

Add 'n' elements to end of list.

References resize(), and size().

Referenced by DD::Image::GeometryList::add_primitive(), append(), and copy().

◆ reserve()

void Attribute::reserve ( unsigned  size)

Reserve memory in list for 'n' elements. If you already know the maximum size of the attribute, this can save a lot of overhead if you call this before adding single elements.

References DD::Image::FLOAT_ATTRIB, DD::Image::INT_ATTRIB, DD::Image::INVALID_ATTRIB, DD::Image::MATRIX3_ATTRIB, DD::Image::MATRIX4_ATTRIB, DD::Image::NORMAL_ATTRIB, DD::Image::POINTER_ATTRIB, size(), DD::Image::STD_STRING_ATTRIB, DD::Image::STRING_ATTRIB, type_, DD::Image::VECTOR2_ATTRIB, DD::Image::VECTOR3_ATTRIB, and DD::Image::VECTOR4_ATTRIB.

◆ resize()

void Attribute::resize ( size_t  size)

Expand or contract element list size to 'n' elements.
