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 polymophism 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.
