MetaAccess is a wrapper for the Metadata array. It can be used to add metadata to and remove metadata from its origin.

Properties

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.

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.

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.

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.

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.
