This is a block of data that receives the results of DCPacker.
Definition dcPackData.h:22
This defines the internal interface for packing values into a DCField.
virtual bool do_check_match_switch_parameter(const DCSwitchParameter *other) const
Returns true if this field matches the indicated switch parameter, false otherwise.
virtual DCPackerInterface * get_nested_field(int n) const
Returns the DCPackerInterface object that represents the nth nested field.
Represents the type specification for a single parameter within a field specification.
