public final class ExceptionsAttribute_info
extends Attribute_info

The Exceptions attribute is a variable-length attribute used in the attributes table of a Method_info structure. The Exceptions attribute indicates which checked exceptions a method may throw. There must be exactly one Exceptions attribute in each method_info structure.

The Exceptions attribute has the following format:

 Exceptions_attribute {
          u2 attribute_name_index;
          u4 attribute_length;
          u2 number_of_exceptions;
          u2 exception_index_table[number_of_exceptions];
  }
 

The value of the number_of_exceptions item indicates the number of entries in the exception_index_table.

Each nonzero value in the exception_index_table array must be a valid index into the constant_pool table. For each table item, if exception_index_table[i] != 0 , where 0 < i < number_of_exceptions, then the constant_pool entry at index exception_index_table[i] must be a CONSTANT_Class_info structure representing a class type that this method is declared to throw -- see DeclaredExceptionTable.
