NAME

6       SQL::Statement::TermFactory - Factory for SQL::Statement::Term
7       instances
8

SYNOPSIS

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

DESCRIPTION

15       This package implements a factory to create type and operation based
16       terms.  Those terms are used to access data from the table(s) - either
17       when evaluating the where clause or returning column data.
18
19       The concept of a factory can be studied in Design Patterns by the Gang
20       of Four. The concept of using polymorphism instead of conditions is
21       suggested by Martin Fowler in his book Refactoring.
22

METHODS

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