Documentation

ASCII Parameter Table Object. This class implements the HCL associative array (hash table) interface defined in the AbstractTable base class.

The principal Table constructor reads the Table's internal data from a "config" file. Each line of the config file is either of the form "Key = Value" or "Object::Key = Value". The first form initializes the parameter associated to "Key" in the table to the value "Value". The second form facilitates the use of one config file for several different objects. If the "Object" matches one of the object names provided by the user (as argument to the constructor, see below), then the parameter is read/written as before. Otherwise, the line is ignored. The type of "Value" can be integer, float, double, or string. String values are optionally enclosed by double-quotes.

Because the keys (strings) are private data for this class, it is a bit on the profligate side with storage.

Constructors, destructor

Table(char *fname = NULL, char *prefixes = NULL, int size = 16)
Create a Table object and initialize it from a file
Parameters:
fname - Name of file to read parameters from or NULL.
prefixes - Space-seperated list of object names. This determines which lines in the file apply to this object. (See the class description.)
size - Initial table size or 0. The table will grow as needed, but it is somewhat more efficient to provide a good size to start with.

Table( const Table & S )
Copy constructor

virtual ~Table()
Destructor

int Merge(char *fname)
Merge entries from a file into the parameter table
Parameters:
fname - File name.

This class has no child classes.
