bool vil_nitf2_typed_array_field< T >::value | ( | const vil_nitf2_index_vector & | indexes, |
T & | out_value | ||
) | const |
Set out_value to the scalar value at the specified index vector, and returns whether specified element was defined.
The length of the index vector must equal num_dimensions(), and check_index(indexes) must return true to indicate that the indexes are within bounds. Even so, this method may return false if the value is undefined at the specified index. (This is a partial override of overloaded method vil_nitf2_array_field::value() for my specific type.)

virtual bool vil_nitf2_array_field::value | ( | const vil_nitf2_index_vector & | , |
int & | |||
) | const [inline, virtual, inherited] |
Sets out_value to the value of the element selected by specified index vector, which must satisfy check_index().
Returns true iff the value is defined. Note that this may return false because the value is unspecified (i.e., blank), even if the index is valid.
Subclasses overload the appropriate method to set out parameter and return true. The implementation here return false. These methods are defined here for the convenience of my callers, so they don't have to downcast to the specific field type.
