- All Known Subinterfaces:
TagResolver.Single,TagResolver.WithoutArguments
A resolver can handle anywhere from a single tag, to a dynamically generated set of tags, returning a tag based on the provided name and arguments.

Method Details
-
builder
Create a new builder for a tag resolver.- Returns:
- the tag resolver builder
- Since:
- 4.10.0
-
standard
Get the tag resolver that resolves allstandard tags.This is the default resolver used by parsers.
- Returns:
- the default resolver
- Since:
- 4.10.0
-
empty
An empty tag resolver that will returnnullfor all resolve attempts.- Returns:
- the tag resolver
- Since:
- 4.10.0
-
resolver
static @NotNull TagResolver.Single resolver(@TagPattern @NotNull @NotNull String name, @NotNull @NotNull Tag tag) A tag resolver that will resolve a single tag by a case-insensitive key.- Parameters:
name- the name of the tag to resolvetag- the tag logic to return- Returns:
- a new tag resolver
- Since:
- 4.10.0
-
resolver
@NotNull static @NotNull TagResolver resolver(@TagPattern @NotNull @NotNull String name, @NotNull @NotNull BiFunction<ArgumentQueue, Context, Tag> handler) Create a tag resolver that only responds to a single tag name, and whose value does not depend on that name.- Parameters:
name- the name to respond tohandler- the tag handler, may throwParsingExceptionif provided arguments are in an invalid format- Returns:
- a resolver that creates tags using the provided handler
- Since:
- 4.10.0
-
resolver
@NotNull static @NotNull TagResolver resolver(@NotNull @NotNull Set<String> names, @NotNull @NotNull BiFunction<ArgumentQueue, Context, Tag> handler) Create a tag resolver that only responds to certain tag names, and whose value does not depend on that name.- Parameters:
names- the names to respond tohandler- the tag handler, may throwParsingExceptionif provided arguments are in an invalid format- Returns:
- a resolver that creates tags using the provided handler
- Since:
- 4.10.0
-
resolver
Constructs a tag resolver capable of resolving from multiple sources.The last specified resolver takes priority.
- Parameters:
resolvers- the tag resolvers- Returns:
- the tag resolver
- Since:
- 4.10.0
-
resolver
@NotNull static @NotNull TagResolver resolver(@NotNull @NotNull Iterable<? extends TagResolver> resolvers) Constructs a tag resolver capable of resolving from multiple sources.The last specified resolver takes priority.
The provided iterable is copied. This means changes to the iterable will not reflect in the returned resolver.
- Parameters:
resolvers- the tag resolvers- Returns:
- the tag resolver
- Since:
- 4.10.0
-
caching
Constructs a tag resolver capable of caching resolved tags.The resolver can return
nullto indicate it cannot resolve a placeholder. Once a string to replacement mapping has been created, it will be cached to avoid the cost of recreating the replacement.Due to the complexity of handling lookups for tags with arguments, the built-in cache does not support anything but tags without arguments.
- Parameters:
resolver- the resolver- Returns:
- the caching tag resolver
- Since:
- 4.10.0
-
toTagResolver
A collector that will combine a stream of resolvers into one joined resolver.- Returns:
- a collector for tag resolvers
- Since:
- 4.10.0
-
resolve
@Nullable @Nullable Tag resolve(@TagPattern @NotNull @NotNull String name, @NotNull @NotNull ArgumentQueue arguments, @NotNull @NotNull Context ctx) throws ParsingException Gets a tag from this resolver based on the current state.- Parameters:
name- the tag namearguments- the arguments passed to the tagctx- the parse context- Returns:
- a possible tag
- Throws:
ParsingException- if the provided arguments are invalid- Since:
- 4.10.0
-
has
Get whether this resolver handles tags with a certain name.This does not allow validating arguments.
- Parameters:
name- the tag name- Returns:
- whether this resolver has a tag with this name
- Since:
- 4.10.0
