Provides functionality to cast a query result value into the correct ruby type. Requires originating table and column to be known.
Creates a new TypeCastingCursor based on provided database connection and table name for the provided database query cursor
# File lib/rubyrep/type_casting_cursor.rb, line 18 def initialize(connection, table, cursor) self.org_cursor = cursor self.columns = {} connection.columns(table).each {|c| columns[c.name] = c} end
# File lib/rubyrep/type_casting_cursor.rb, line 8 def clear; org_cursor.clear end
Delegate the uninteresting methods to the original cursor
# File lib/rubyrep/type_casting_cursor.rb, line 7 def next?; org_cursor.next? end
Reads the next row from the original cursor and returns the row with the type casted row values.
# File lib/rubyrep/type_casting_cursor.rb, line 25 def next_row row = org_cursor.next_row row.each {|column, value| row[column] = columns[column].type_cast value} row end
