## Detailed Description

The ArraySample class is a reference to a block of memory corresponding to an array of instances of DataTypes. The array may be multi-rank, with different sizes in each dimension, but with its data ultimately stored contiguously. The class is basically just a bundle of a memory address, stored as a void*, a DataType, and a Dimension.

The ArraySample itself does not pretend to own the data referred to memory address "data". It is just a reference. For data retention mgmt, see the note on ArraySamplePtr below.

## Constructor & Destructor Documentation

## ArraySample() [1/2]

Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::ArraySample::ArraySample | ( |  | ) |

inline

Default constructor creates NULL bytes with degenerate dimensions. ...

## ArraySample() [2/2]

Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::ArraySample::ArraySample | ( | const void * | iData,
|  | const DataType & | iDataType,
|  | const Dimensions & | iDims )

inline

Explicit constructor takes bytes and dims by reference and creates its own reference to them.

## Member Function Documentation

## getData()

const void * Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::ArraySample::getData | ( |  | ) | const

inline

Using Default Copy Constructor Using Default Assignment Operator

Return the data as a raw pointer ...

## getDataType()

const DataType & Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::ArraySample::getDataType | ( |  | ) | const

inline

Return the datatype. ...

## getDimensions()

const Dimensions & Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::ArraySample::getDimensions | ( |  | ) | const

inline

Return the dimensions ...

## getKey()

ArraySample::Key Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::ArraySample::getKey | ( |  | ) | const

Compute the Key. This is a calculation.

## reset()

void Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::ArraySample::reset | ( |  | ) |

inline

Reset the array sample to an empty, invalid state. Basically the same as calling *this = ArraySample();

## size()

size_t Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::ArraySample::size | ( |  | ) | const

inline

Return the "size", which is getDimensions().numPoints() ...

## valid()

bool Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::ArraySample::valid | ( |  | ) | const

inline

Return if it is valid. An empty ArraySample is valid. however, an ArraySample that is empty and has a scalar dimension is invalid. This is how we discriminate between setting a sample of length zero (useful in particle systems) vs. indicating an invalid sample (NULL).
