NAME
       SQL::Statement::TermFactory - Factory for SQL::Statement::Term instances


SYNOPSIS
         my $termFactory = SQL::Statement::TermFactory->new($stmt);
         my $whereTerms = $termFactory->buildCondition( $stmt->{where_clause} );
         my $col = $termFactory->buildCondition( $stmt->{col_obj}->{$name}->{content} );


DESCRIPTION
       This package implements a factory to create type and operation based terms.  Those terms are used to
       access data from the table(s) - either when evaluating the where clause or returning column data.

       The concept of a factory can be studied in Design Patterns by the Gang of Four. The concept of using
       polymorphism instead of conditions is suggested by Martin Fowler in his book Refactoring.


METHODS
   buildCondition
       Builds a condition object from a given (part of a) where clause. This method calls itself recursively for
       predicates.
