Interface ClassFile.AttributeMapperOption

public static sealed interface ClassFile.AttributeMapperOption extends ClassFile.Option
The option describing user-defined attributes for parsing class files. The default does not recognize any user-defined attribute.

An AttributeMapperOption contains a function that maps an attribute name to a user attribute mapper. The function may return null if it does not recognize an attribute name. The returned mapper must ensure its name() is equivalent to the stringValue() of the input Utf8Entry.

The mapping function in this attribute has lower priority than mappers in Attributes, so it is impossible to override built-in attributes with this option. If an attribute is not recognized by any mapper in Attributes and is not assigned a mapper, or recognized, by this option, that attribute will be modeled by an UnknownAttribute.
