## 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

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.

Authors:
  Graeme Rocher

Since:
  0.1

Field Summary
`static NamingStrategy` | `namingStrategy` Overrideable naming strategy.

Method Summary
`static void` | `bindClass(GrailsDomainClass domainClass, Mappings mappings)` Binds a Grails domain class to the Hibernate runtime meta model
`protected static void` | `bindNumericColumnConstraints(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.
`static void` | `bindRoot(GrailsDomainClass domainClass, Mappings mappings)` Binds a root class (one with no super classes) to the runtime meta model based on the supplied Grails domain class
`protected static void` | `bindStringColumnConstraints(Column column, ConstrainedProperty constrainedProperty)` Interrogates the specified constraints looking for any constraints that would limit the length of the property's value.
`static void` | `configureNamingStrategy(java.lang.Object strategy)` Override the default naming strategy given a Class or a full class name.
`protected static void` | `createClassProperties(GrailsDomainClass domainClass, PersistentClass persistentClass, Mappings mappings)` Creates and binds the properties for the specified Grails domain class and PersistantClass and binds them to the Hibernate runtime meta model
`static Mapping` | `evaluateMapping(GrailsDomainClass domainClass)` Evaluates a Mapping object from the domain class if it has a mapping closure
`static Mapping` | `evaluateMapping(GrailsDomainClass domainClass, groovy.lang.Closure defaultMapping)`
`static Mapping` | `getMapping(java.lang.Class theClass)` Obtains a mapping object for the given domain class nam
`static Mapping` | `getMapping(GrailsDomainClass domainClass)` Obtains a mapping object for the given domain class nam
`static PropertyConfig` | `getPropertyConfig(GrailsDomainClassProperty property)`

Field Detail

### namingStrategy

    public static NamingStrategy namingStrategy

  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, Mappings mappings)

  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

### bindNumericColumnConstraints

    protected static void bindNumericColumnConstraints(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, Mappings mappings)

  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

### bindStringColumnConstraints

    protected static void bindStringColumnConstraints(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 given a Class or a full class name.
  throws:
    ClassNotFoundException
  throws:
    InstantiationException
  throws:
    IllegalAccessException
  Parameters:
    `strategy` - the class or name

### createClassProperties

    protected static void createClassProperties(GrailsDomainClass domainClass, PersistentClass persistentClass, Mappings mappings)

  Creates and binds the properties for the specified Grails domain class and PersistantClass and binds them to the Hibernate runtime meta model
  Parameters:
    `domainClass` - The Grails domain class
    `persistentClass` - The Hibernate PersistentClass instance
    `mappings` - The Hibernate Mappings instance

### evaluateMapping

    public static Mapping evaluateMapping(GrailsDomainClass domainClass)

  Evaluates a Mapping object from the domain class if it has a mapping closure
  Parameters:
    `domainClass` - The domain class
  Returns:
    the mapping

### evaluateMapping

    public static Mapping evaluateMapping(GrailsDomainClass domainClass, groovy.lang.Closure defaultMapping)

### getMapping

    public static Mapping getMapping(java.lang.Class theClass)

  Obtains a mapping object for the given domain class nam
  Parameters:
    `theClass` - The domain class in question
  Returns:
    A Mapping object or null

### getMapping

    public static Mapping getMapping(GrailsDomainClass domainClass)

  Obtains a mapping object for the given domain class nam
  Parameters:
    `domainClass` - The domain class in question
  Returns:
    A Mapping object or null

### getPropertyConfig

    public static PropertyConfig getPropertyConfig(GrailsDomainClassProperty property)
