Member Function Documentation

Load()

bool Deki::AssetLookupTable::Load ( const uint8_t * data, size_t size )

static

Load the asset lookup table from memory.

The data must remain valid for the lifetime of lookups. Typically loaded from SD card or flash memory.

Parameters

data	Pointer to binary table data
size	Size of data in bytes

Returns

true on success

Unload()

void Deki::AssetLookupTable::Unload ( )

static

Unload the lookup table.

IsLoaded()

bool Deki::AssetLookupTable::IsLoaded ( )

inlinestatic

Check if table is loaded.

Lookup()

const char * Deki::AssetLookupTable::Lookup ( uint32_t hash )

static

Look up GUID by hash (binary search).

Parameters

hash	FNV-1a hash of "path:type" key

Returns

GUID string or nullptr if not found

Hash()

uint32_t Deki::AssetLookupTable::Hash ( const char * path, const char * type )

static

Compute FNV-1a hash of a path:type key.

Parameters

path	Asset path (e.g., "scenes/Demo")
type	Asset type name (e.g., "Scene")

Returns

Hash value

HashString()

uint32_t Deki::AssetLookupTable::HashString ( const char * str )

static

Compute FNV-1a hash of a string.

Parameters

str	String to hash

Returns

Hash value

GetEntryCount()

uint32_t Deki::AssetLookupTable::GetEntryCount ( )

inlinestatic

Get entry count.

ContainsGuid()

bool Deki::AssetLookupTable::ContainsGuid ( const char * guid )

static

Check if a GUID exists in the table.

Parameters

guid	GUID string to find

Returns

true if GUID exists as a value in any entry

O(n) scan - acceptable for asset loading (not per-frame)
