import haxe.macro.Type
Available on all platformsMetaAccess 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.
