Detailed Description

Abstract interface for providing two-way metatile terrain type mappings.

The TerrainTypeMapProvider maps terrain type constant names (e.g., "TILE_TERRAIN_GRASS", "TILE_TERRAIN_WATER") to their corresponding uint8_t values and vice versa. Implementations may load these mappings from various sources such as header files or configuration. Loading and caching strategies are implementation details left to concrete implementations.

Member Function Documentation

◆ lookup() [1/2]

virtual ChainableResult< std::uint8_t > porytiles::TerrainTypeMapProvider::lookup ( const std::string & terrain_name ) const

pure virtual

Looks up the numeric value for a terrain type constant name.

This function searches for the given terrain type constant name in the provider's mapping and returns its corresponding numeric value if found.

Parameters

terrain_name The terrain type constant name (e.g., "TILE_TERRAIN_GRASS")

Returns: The numeric value if found, or an error describing why the lookup failed

Implemented in porytiles::HeaderTerrainTypeMapProvider.

◆ lookup() [2/2]

virtual ChainableResult< std::string > porytiles::TerrainTypeMapProvider::lookup ( std::uint8_t terrain_value ) const

pure virtual

Looks up the terrain type constant name for a numeric value.

This function performs a reverse lookup, searching for the terrain type constant name that corresponds to the given numeric value.
