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.
