Method Details

addPack

public void addPack(ResourcePack pack)

getAllNamespaces

@Environment(CLIENT)
public Set<String> getAllNamespaces()

Gets a set of all namespaces offered by the resource packs loaded by this manager.

Specified by:

getAllNamespaces in interface ResourceManager

getResource

public Resource getResource(Identifier id)
                     throws IOException

Finds and returns the corresponding resource for a resource's identifier.
Starts by scanning each resource pack from highest priority to lowest. If no resource packs were found to contain the requested entry, will throw a FileNotFoundException.

Specified by:

getResource in interface ResourceManager

Parameters:

id - the resource identifier to search for

Throws:

FileNotFoundException - if the identified resource could not be found, or could not be loaded.

IOException - if the identified resource was found but a stream to it could not be opened.

containsResource

@Environment(CLIENT)
public boolean containsResource(Identifier id)

Checks whether any of the currently-loaded resource packs contain an entry for the given id.
Starts by querying the resource pack with the highest priority to lowest until it finds one that responds to the requested identifier.

Specified by:

containsResource in interface ResourceManager

Parameters:

id - the resource identifier to search for

open

protected InputStream open(Identifier id,
ResourcePack pack)
                    throws IOException

Throws:

IOException

validate

private void validate(Identifier id)
               throws IOException

Throws:

IOException

isPathAbsolute

private boolean isPathAbsolute(Identifier id)

getAllResources

public List<Resource> getAllResources(Identifier id)

Gets all of the available resources to the corresponding resource identifier.
Resources are returned in load order, or ascending order of priority, so the last element in the returned list is what would be returned normally by getResource(net.minecraft.util.Identifier)

Specified by:

getAllResources in interface ResourceManager

Parameters:

id - the resource identifier to search for

Throws:

FileNotFoundException - if no matching resources could be found (i.e. if the list would be empty)

IOException - if resources were found, but any one of them could not be opened to be read.

findResources

public Collection<Identifier> findResources(String startingPath,
Predicate<String> pathPredicate)

Returns a sorted list of identifiers matching a path predicate.
Scanning begins in startingPath and each candidate file present under that directory will be offered up to the predicate to decide whether it should be included or not.
Elements in the returned list may not, necessarily be unique. Additional effort is advised to ensure that duplicates in the returned list are discarded before loading.

Specified by:

findResources in interface ResourceManager

Parameters:

startingPath - the starting path to begin scanning from

pathPredicate - a predicate to determine whether a path should be included or not

Returns:

the list matching identifiers

streamResourcePacks

@Environment(CLIENT)
public Stream<ResourcePack> streamResourcePacks()

Gets a stream of loaded resource packs in increasing order of priority.

Specified by:

streamResourcePacks in interface ResourceManager

getMetadataPath

static Identifier getMetadataPath(Identifier id)
