Detailed Description
A single molecular field of a Distributed Class, as read from a .dc file.
This represents a combination of two or more related atomic fields, that will often be treated as a unit.

Member Function Documentation
◆ add_atomic()
| void DCMolecularField::add_atomic | ( | DCAtomicField * | atomic | ) |
Adds the indicated atomic field to the end of the list of atomic fields that make up the molecular field.
This is normally called only during parsing of the dc file. The atomic field should be fully defined by this point; you should not modify the atomic field (e.g. by adding more elements) after adding it to a molecular field.
Definition at line 74 of file dcMolecularField.cxx.
References DCKeywordList::copy_keywords(), DCPackerInterface::get_num_nested_fields(), and DCField::is_bogus_field().
◆ as_molecular_field() [1/2]
|
virtual |
Returns the same field pointer converted to a molecular field pointer, if this is in fact a molecular field; otherwise, returns NULL.
Reimplemented from DCField.
Definition at line 34 of file dcMolecularField.cxx.
◆ as_molecular_field() [2/2]
|
virtual |
Returns the same field pointer converted to a molecular field pointer, if this is in fact a molecular field; otherwise, returns NULL.
Reimplemented from DCField.
Definition at line 43 of file dcMolecularField.cxx.
◆ generate_hash()
|
virtual |
Accumulates the properties of this field into the hash.
Reimplemented from DCField.
Definition at line 147 of file dcMolecularField.cxx.
References HashGenerator::add_int(), and DCField::generate_hash().
◆ get_atomic()
| DCAtomicField * DCMolecularField::get_atomic | ( | int | n | ) | const |
Returns the nth atomic field that makes up this molecular field.
This may or may not be a field of this particular class; it might be defined in a parent class.
Definition at line 61 of file dcMolecularField.cxx.
◆ get_nested_field()
|
virtual |
Returns the DCPackerInterface object that represents the nth nested field.
This may return NULL if there is no such field (but it shouldn't do this if n is in the range 0 <= n < get_num_nested_fields()).
Reimplemented from DCPackerInterface.
Definition at line 163 of file dcMolecularField.cxx.
◆ get_num_atomics()
| int DCMolecularField::get_num_atomics | ( | ) | const |
Returns the number of atomic fields that make up this molecular field.
Definition at line 51 of file dcMolecularField.cxx.
◆ write()
|
virtual |
Generates a parseable description of the object to the indicated output stream.
Implements DCField.
