Method Details

getColumnName

public static String getColumnName(Constrained constrained,
 String propertyName)

Retrieves the database column name that a bean property maps to.

This method will return the explicit column name when the property has been constrained with one, otherwise the column name is simply the property name. This makes it possible to use column names that can't be expressed as bean property names.

Parameters:

constrained - the constrained bean to look the property up in; or null when the bean isn't constrained

propertyName - the name of the bean property

Returns:

the column name to use for the property
