Class ResultSetReflector

java.lang.Object
  net.sf.morph.reflect.reflectors.BaseReflector
      net.sf.morph.reflect.reflectors.BaseBeanReflector
          net.sf.morph.reflect.reflectors.ResultSetReflector

All Implemented Interfaces:

net.sf.composite.Component, BeanReflector, ContainerReflector, DecoratedReflector, Reflector, SizableReflector

public class ResultSetReflector
extends BaseBeanReflector
implements BeanReflector, ContainerReflector

Exposes the information in a ResultSet. This reflector can function both as a container reflector and as a bean reflector. When functionining a container reflector, this reflector exposes the rows in a ResultSet. As a bean reflector, this reflector exposes the column names from a particular row of a ResultSet as properties. The column names are always converted to all lowercase.

Note: Code from the getImpl(Object, String) method was taken from Spring's JdbcUtils class.

Method Detail

getContainedTypeImpl

protected java.lang.Class getContainedTypeImpl(java.lang.Class clazz)
                                        throws java.lang.Exception

Description copied from class: BaseReflector

Implementation of ContainerReflector.getContainedType(Class).

Overrides:

getContainedTypeImpl in class BaseReflector

Throws:

java.lang.Exception

getIteratorImpl

protected java.util.Iterator getIteratorImpl(java.lang.Object container)
                                      throws java.lang.Exception

Description copied from class: BaseReflector

Implementation of ContainerReflector.getIterator(Object).

Overrides:

getIteratorImpl in class BaseReflector

Throws:

java.lang.Exception

getPropertyNamesImpl

protected java.lang.String[] getPropertyNamesImpl(java.lang.Object bean)
                                           throws java.lang.Exception

Description copied from class: BaseBeanReflector

Template method must be overridden. Implementation of BeanReflector.getPropertyNames(Object). Implementation automatically provided for IndexedContainerReflectors. For other reflectors, throws an UnsupportedOperationException.

Specified by:

getPropertyNamesImpl in class BaseBeanReflector

Throws:

java.lang.Exception

getTypeImpl

protected java.lang.Class getTypeImpl(java.lang.Object bean,
                                      java.lang.String propertyName)
                               throws java.lang.Exception

Description copied from class: BaseBeanReflector

Template method must be overridden. Implementation of BeanReflector.getType(Object, String). Default implementation provided. For IndexedContainerReflectors, returns the type by calling ContainerReflector.getContainedType(Class). For other reflectors, checks the type of the property by calling BaseReflector.get(Object, String).

Specified by:

getTypeImpl in class BaseBeanReflector

Throws:

java.lang.Exception

isWriteableImpl

protected boolean isWriteableImpl(java.lang.Object bean,
                                  java.lang.String propertyName)
                           throws java.lang.Exception

Description copied from class: BaseReflector

Implementation of BeanReflector.isWriteable(Object, String). Default implementation assumes that all readable properties are also writeable. One exception to this is when this reflector is an IndexedContainerReflector but not a MutableIndexedContainerReflector, in which case no properties are considered writeable.

Overrides:

isWriteableImpl in class BaseReflector

Throws:

java.lang.Exception

getImpl

protected java.lang.Object getImpl(java.lang.Object bean,
                                   java.lang.String propertyName)
                            throws java.lang.Exception

NOTE: Code copied here from Spring's JdbcUtils class.

Specified by:

getImpl in class BaseBeanReflector

Throws:

java.lang.Exception

setImpl

protected void setImpl(java.lang.Object bean,
                       java.lang.String propertyName,
                       java.lang.Object value)
                throws java.lang.Exception

Description copied from class: BaseBeanReflector

Template method must be overridden. Implementation of BeanReflector.set(Object, String, Object). Implementation automatically provided for MutableIndexedContainerReflectors. For other reflectors, throws an UnsupportedOperationException.

Specified by:

setImpl in class BaseBeanReflector

Throws:

java.lang.Exception

getReflectableClassesImpl

protected java.lang.Class[] getReflectableClassesImpl()
                                               throws java.lang.Exception

Description copied from class: BaseReflector

Implementation of Reflector.getReflectableClasses().

Specified by:

getReflectableClassesImpl in class BaseReflector

Throws:

java.lang.Exception

isStrictlyTyped

public boolean isStrictlyTyped()

Description copied from class: BaseReflector

Indicates whether this reflector is strictly typed. If a reflector is strictly typed, the BaseReflector.getType(Object, String) method will throw an exception if the requested property name is not a valid property of the object. Default implementation returns false.

Overrides:

isStrictlyTyped in class BaseReflector

Returns:

false.
