| addQuotes | | protected String addQuotes(Object value)(Code) | | Adds quotes to an object for storage in postgis. The object should be a
string or a number. To perform an insert strings need quotes around
them, and numbers work fine with quotes, so this method can be called
on unknown objects.
Parameters:
value - The object to add quotes to. a string representation of the object with quotes. |
| encodeName | | protected String encodeName(String tableName)(Code) | | Encodes the tableName, default is to do nothing, but postgis will
override and put double quotes around the tablename.
|
| getGeometryInsertText | | abstract protected String getGeometryInsertText(Geometry geom, int srid) throws IOException(Code) | | Turns a geometry into the textual version needed for the sql statement
Parameters:
geom -
Parameters:
srid - |
| makeInsertSql | | protected String makeInsertSql(Feature feature) throws IOException(Code) | | Creates a sql insert statement. Uses each feature's schema, which makes
it possible to insert out of order, as well as inserting less than all
features.
Parameters:
feature - the feature to add. an insert sql statement.
throws:
IOException - |
| makeSelectForUpdateSql | | protected String makeSelectForUpdateSql(Feature current)(Code) | | Generate the select for update statement, which will attempt to
lock features for update. This should be overwritten by databases
which want to take advantage of this method.
This method is called in a timer thread, to prevent blocking.
