Attribute PlayedBy
Intent
The PlayedBy attribute is a fixed-length attribute used in the attributes table of the ClassFile structure.
Location:
A role class which, or which super role class, is bound to a base class.
Content:
The name of the bound base class.
Purpose:
The OTRE does not use this attribute at the moment(?).
Format:
PlayedBy {
u2 attribute_name_index;
u4 attribute_length;
u2 base_class_name_index;
}
The items of the PlayedBy structure are as follows:
- attribute_name_index
- The constant_pool entry at that index must be a CONSTANT_Utf8_info representing the string "CallinRoleBaseBindings".
- attribute_length
- The value of the attribute_length item indicates the length of the attribute, excluding the initial six bytes.
- base_class_name_index
- The constant_pool index representing the fully qualified name of the base class, as given in the source code from which this class file was compiled.
