MetaAccess is a wrapper for the Metadata array. It can be used to add
metadata to and remove metadata from its origin.
Fields
remove(name:String):Void
Removes all name metadata entries from the origin of this
MetaAccess.
This method might clear several metadata entries of the same name.
If a Metadata array is obtained through a call to get, a subsequent
call to remove has no effect on that array.
If name is null, compilation fails with an error.
has(name:String):Bool
Tells if the origin of this MetaAccess has a name metadata entry.
If name is null, compilation fails with an error.
get():Metadata
Return the wrapped Metadata array.
Modifying this array has no effect on the origin of this MetaAccess.
The add and remove methods can be used for that.
extract(name:String):Array<MetadataEntry>
Extract metadata entries by given name.
If there's no metadata with such name, empty array [] is returned.
If name is null, compilation fails with an error.
add(name:String, params:Array<Expr>, pos:Position):Void
Adds the metadata specified by name, params and pos to the origin
of this MetaAccess.
Metadata names are not unique during compilation, so this method never overwrites a previous metadata.
If a Metadata array is obtained through a call to get, a subsequent
call to add has no effect on that array.
If any argument is null, compilation fails with an error.
