Static Public Member Functions
static uint64_t	encode (const Index &a_point) noexcept
	Encode the input point into the SFC code.
static Index	decode (const uint64_t &a_code) noexcept
	Decode the 64-bit SFC code into an Index.

Detailed Description

Implementation of a nested index SFC.

The SFC is encoded by the code = i + j * N + k * N * N in 3D, where i,j,k are the block indices.

Member Function Documentation

decode()

static Index EBGeometry::SFC::Nested::decode ( const uint64_t &  a_code )

inlinestaticnoexcept

Decode the 64-bit SFC code into an Index.

Parameters

[in]

a_code

SFC code to decode. Must be a code actually produced by encode(), i.e. at most (ValidSpan+1)^3 - 1.

Returns

3D grid index corresponding to a_code.

encode()

static uint64_t EBGeometry::SFC::Nested::encode ( const Index &  a_point )

inlinestaticnoexcept

Encode the input point into the SFC code.

Parameters

[in]

a_point

3D grid index to encode. Each component must be <= ValidSpan.

Returns

64-bit nested SFC code for a_point.
