Detailed Description

template<class T, rowsize _row_size = 1, rowsize _row_max = _row_size, rowsize _align = NoAlign>
class DNDS::ArrayLayout< T, _row_size, _row_max, _align >

Compile-time layout descriptor deducing the concrete DataLayout from element type and row-size template arguments.

Serves as a base class for Array / ArrayView and as a static namespace of helpers (signature strings, compatibility checks). Carries no runtime state of its own.

Template Parameters

T	Element type.
_row_size	Row size (>=0 / DynamicSize / NonUniformSize).
_row_max	Row max (>=0 / DynamicSize / NonUniformSize; only used when `_row_size == NonUniformSize`).
_align	Alignment hint (currently only NoAlign implemented).

◆ _GetDataLayout()

template<class T , rowsize _row_size = 1, rowsize _row_max = _row_size, rowsize _align = NoAlign>

static constexpr DataLayout DNDS::ArrayLayout< T, _row_size, _row_max, _align >::_GetDataLayout ( )

inlinestaticconstexpr

Deduce the DataLayout tag from the template parameters.

Definition at line 100 of file ArrayBasic.hpp.

◆ ArraySignatureIsCompatible()

template<class T , rowsize _row_size = 1, rowsize _row_max = _row_size, rowsize _align = NoAlign>

static bool DNDS::ArrayLayout< T, _row_size, _row_max, _align >::ArraySignatureIsCompatible ( const std::string & v )

inlinestatic

Whether a stored signature can be read into this array type.

Requires matching sizeof(T) and compatible row-size constants: fixed row sizes must be equal when both sides declare them.

◆ GetArrayName()

template<class T , rowsize _row_size = 1, rowsize _row_max = _row_size, rowsize _align = NoAlign>

static std::string DNDS::ArrayLayout< T, _row_size, _row_max, _align >::GetArrayName ( )

inlinestatic

Human-readable type identifier including element typeid, sizes, and alignment.

Format: "<Layout>__<typeid>_<sizeof_T>_<rs>_<rm>_<al>". Primarily for debugging / error messages. Not stable across compilers (uses typeid(T).name()); use GetArraySignature for persisted data.

Here is the caller graph for this function:

◆ GetArraySignature()

template<class T , rowsize _row_size = 1, rowsize _row_max = _row_size, rowsize _align = NoAlign>

static std::string DNDS::ArrayLayout< T, _row_size, _row_max, _align >::GetArraySignature ( )

inlinestatic

Compiler-independent identifier used by serializers to tag an array.

Format: "<Layout>__<sizeof_T>_<rs>_<rm>_<al>", where template parameters are encoded numerically (so -1 = DynamicSize, -2 = NonUniformSize). Stable across compilers; used for compatibility checks during serialized restart.

Definition at line 152 of file ArrayBasic.hpp.

Here is the caller graph for this function:

◆ GetArraySignatureRelaxed()

template<class T , rowsize _row_size = 1, rowsize _row_max = _row_size, rowsize _align = NoAlign>

static std::string DNDS::ArrayLayout< T, _row_size, _row_max, _align >::GetArraySignatureRelaxed ( )

inlinestatic

Signature with _row_size / _row_max replaced by DynamicSize.

Used when we want two arrays to match regardless of compile-time row-size constants (e.g., compare a DynamicSize reader against a fixed-size writer file).

Definition at line 175 of file ArrayBasic.hpp.

◆ ParseArraySignatureTuple()

template<class T , rowsize _row_size = 1, rowsize _row_max = _row_size, rowsize _align = NoAlign>

static std::tuple< int, int, int, int > DNDS::ArrayLayout< T, _row_size, _row_max, _align >::ParseArraySignatureTuple ( const std::string & v )

inlinestatic

Parse a signature string into (sizeof_T, row_size, row_max, align).

Accepts both GetArrayName (6 components incl. typeid) and GetArraySignature (5 components) forms; returns the last 4 fields.
