Member Function Documentation

◆ constructor()

PgsqlSqlUtil::PgsqlPrimaryKey::constructor ( string  n,
*hash  c,
*string  ts 
)

creates the object with the given attributes

Parameters
nname of the constraint
ccolumn hash
tsoptional tablespace name

◆ memberGate()

PgsqlColumn PgsqlSqlUtil::PgsqlPrimaryKey::memberGate ( string  k)

returns the PgsqlColumn value of the given key if it exists, otherwise throws a KEY-ERROR exception

Example:
auto v = c.name;
Parameters
kthe name of the key to access
Returns
the value of the given key in the contained hash if it exists
Exceptions
KEY-ERRORthe given key does not exist in the contained hash
Note
this method is called automatically when an unknown or inaccessible member name is accessed from outside the class
