      Add a new dynamic property with the specified data type, but with no restrictions on readability or writeability.
      Specified by:
      add in interface org.apache.commons.beanutils.MutableDynaClass
      Parameters:
      name - Name of the new dynamic property
      type - Data type of the new dynamic property (null for no restrictions)
      Throws:
      IllegalArgumentException - if name is null
      IllegalStateException - if this DynaClass is currently restricted, so no new properties can be added
    • add

      public void add(String name, Class type, boolean readable, boolean writeable)

      Add a new dynamic property with the specified data type, readability, and writeability.

      N.B.Support for readable/writeable properties has not been implemented and this method always throws a UnsupportedOperationException.

      I'm not sure the intention of the original authors for this method, but it seems to me that readable/writable should be attributes of the DynaProperty class (which they are not) and is the reason this method has not been implemented.

      Specified by:
      add in interface org.apache.commons.beanutils.MutableDynaClass
      Parameters:
      name - Name of the new dynamic property
      type - Data type of the new dynamic property (null for no restrictions)
      readable - Set to true if this property value should be readable
      writeable - Set to true if this property value should be writeable
      Throws:
      UnsupportedOperationException - anytime this method is called
    • add

      protected void add(org.apache.commons.beanutils.DynaProperty property)
      Add a new dynamic property.
      Parameters:
      property - Property the new dynamic property to add.
      Throws:
      IllegalArgumentException - if name is null
      IllegalStateException - if this DynaClass is currently restricted, so no new properties can be added
    • remove

      public void remove(String name)
      Remove the specified dynamic property, and any associated data type, readability, and writeability, from this dynamic class. NOTE - This does NOT cause any corresponding property values to be removed from DynaBean instances associated with this DynaClass.
      Specified by:
      remove in interface org.apache.commons.beanutils.MutableDynaClass
      Parameters:
      name - Name of the dynamic property to remove
      Throws:
      IllegalArgumentException - if name is null
      IllegalStateException - if this DynaClass is currently restricted, so no properties can be removed
    • getDynaProperty

      public org.apache.commons.beanutils.DynaProperty getDynaProperty(String name)

      Return a property descriptor for the specified property.

      If the property is not found and the returnNull indicator is true, this method always returns null.

      If the property is not found and the returnNull indicator is false a new property descriptor is created and returned (although its not actually added to the DynaClass's properties). This is the default beahviour.

      The reason for not returning a null property descriptor is that BeanUtils uses this method to check if a property exists before trying to set it - since these Lazy implementations automatically add any new properties when they are set, returning null from this method would defeat their purpose.

      Specified by:
      getDynaProperty in interface org.apache.commons.beanutils.DynaClass
      Parameters:
      name - Name of the dynamic property for which a descriptor is requested
      Throws:
      IllegalArgumentException - if no property name is specified
