Class MultiWrapDynaBean

java.lang.Object
org.apache.commons.configuration2.builder.combined.MultiWrapDynaBean
All Implemented Interfaces:
org.apache.commons.beanutils.DynaBean
final class MultiWrapDynaBean extends Object implements org.apache.commons.beanutils.DynaBean

An implementation of the DynaBean interfaces which wraps multiple other beans.

An instance of this class is constructed with a collection of beans to be wrapped. When reading or writing a property the wrapped bean which defines this property is determined, and the operation is executed on this bean.

The wrapped beans should have disjunct properties. Otherwise, it is undefined which bean property is read or written.

Since:
2.0

  • Constructor Details

    • MultiWrapDynaBean

      public MultiWrapDynaBean(Collection<?> beans)
      Creates a new instance of MultiWrapDynaBean and initializes it with the given collections of beans to be wrapped.
      Parameters:
      beans - the wrapped beans

  • Method Details

    • createDynaBean

      private static org.apache.commons.beanutils.DynaBean createDynaBean(Object bean)
      Creates a DynaBean object for the given bean.
      Parameters:
      bean - the bean
      Returns:
      the DynaBean for this bean

    • contains

      public boolean contains(String name, String key)
      This operation is not supported by the WrapDynaBean objects used internally by this class. Therefore, just an exception is thrown.
      Specified by:
      contains in interface org.apache.commons.beanutils.DynaBean

    • fetchBean

      private org.apache.commons.beanutils.DynaBean fetchBean(String property)
      Returns the bean instance to which the given property belongs. If no such bean is found, an arbitrary bean is returned. (This causes the operation on this bean to fail with a meaningful error message.)
      Parameters:
      property - the property name
      Returns:
      the bean defining this property
