org.codehaus.groovy.grails.orm.hibernate.cfg
[Java] Class GrailsDomainBinder

java.lang.Object
  org.codehaus.groovy.grails.orm.hibernate.cfg.GrailsDomainBinder

public final class GrailsDomainBinder
extends java.lang.Object

Handles the binding Grails domain classes and properties to the Hibernate runtime meta model. Based on the HbmBinder code in Hibernate core and influenced by AnnotationsBinder.

Field Detail

NAMING_STRATEGIES

public static org.hibernate.mapping.Map NAMING_STRATEGIES
Overrideable naming strategy. Defaults to ImprovedNamingStrategy but can be configured in DataSource.groovy via hibernate.naming_strategy = ....

 
Method Detail

bindClass

public static void bindClass(GrailsDomainClass domainClass, org.hibernate.cfg.Mappings mappings, java.lang.String sessionFactoryBeanName)
Binds a Grails domain class to the Hibernate runtime meta model
throws:
MappingException Thrown if the domain class uses inheritance which is not supported
Parameters:
domainClass - The domain class to bind
mappings - The existing mappings
sessionFactoryBeanName - the session factory bean name

bindNumericColumnConstraints

protected static void bindNumericColumnConstraints(org.hibernate.mapping.Column column, ConstrainedProperty constrainedProperty)
Interrogates the specified constraints looking for any constraints that would limit the precision and/or scale of the property's value. If such constraints exist, this method adjusts the precision and/or scale of the column accordingly.
Parameters:
column - the column that corresponds to the property
constrainedProperty - the property's constraints

bindRoot

public static void bindRoot(GrailsDomainClass domainClass, org.hibernate.cfg.Mappings mappings, java.lang.String sessionFactoryBeanName)
Binds a root class (one with no super classes) to the runtime meta model based on the supplied Grails domain class
Parameters:
domainClass - The Grails domain class
mappings - The Hibernate Mappings object
sessionFactoryBeanName - the session factory bean name

bindStringColumnConstraints

protected static void bindStringColumnConstraints(org.hibernate.mapping.Column column, ConstrainedProperty constrainedProperty)
Interrogates the specified constraints looking for any constraints that would limit the length of the property's value. If such constraints exist, this method adjusts the length of the column accordingly.
Parameters:
column - the column that corresponds to the property
constrainedProperty - the property's constraints

configureNamingStrategy

public static void configureNamingStrategy(java.lang.Object strategy)
Override the default naming strategy for the default datasource given a Class or a full class name.
throws:
ClassNotFoundException
throws:
InstantiationException
throws:
IllegalAccessException
Parameters:
strategy - the class or name

configureNamingStrategy

public static void configureNamingStrategy(java.lang.String datasourceName, java.lang.Object strategy)
Override the default naming strategy given a Class or a full class name.
throws:
ClassNotFoundException
throws:
InstantiationException
throws:
IllegalAccessException
Parameters:
datasourceName - the datasource name
strategy - the class or name

createClassProperties

protected static void createClassProperties(GrailsDomainClass domainClass, org.hibernate.mapping.PersistentClass persistentClass, org.hibernate.cfg.Mappings mappings, java.lang.String sessionFactoryBeanName)
Creates and binds the properties for the specified Grails domain class and PersistentClass and binds them to the Hibernate runtime meta model
Parameters:
domainClass - The Grails domain class
persistentClass - The Hibernate PersistentClass instance
