cleanup

public void cleanup()

Clean up strong reference. It should be called by end of deployment or deploytool.

isPropertyDefined

protected boolean isPropertyDefined(String propertyValue)

Returns true if the specified propertyValue represents a defined value, false otherwise. This implementation returns true if the value is not empty, but subclasses may override this method to compare to a constant which represents an undefined value.

Parameters:

propertyValue - the value to be tested for defined

Returns:

true if the specified propertyValue represents a defined value, false otherwise

Update column in the SchemaElement with jdbc type and its length, scale and precision.

Parameters:

column - a ColumnElement to be updated

jdbcType - jdbc type from java.sql.Types

length - an Integer for length or null if it does not apply

scale - an Integer for scale or null if it does not apply
