 org.apache.commons.beanutils.BasicDynaBean
| BasicDynaBean | | public class BasicDynaBean implements DynaBean,Serializable(Code) | | Minimal implementation of the DynaBean interface. Can be
used as a convenience base class for more sophisticated implementations.
IMPLEMENTATION NOTE - Instances of this class that are
accessed from multiple threads simultaneously need to be synchronized.
IMPLEMENTATION NOTE - Instances of this class can be
successfully serialized and deserialized ONLY if all
property values are Serializable.

is associated with.
|
| values | | protected HashMap values(Code) | | The set of property values for this DynaBean, keyed by property name.
|
| BasicDynaBean | | public BasicDynaBean(DynaClass dynaClass)(Code) | | Construct a new DynaBean associated with the specified
DynaClass instance.
Parameters:
dynaClass - The DynaClass we are associated with |
| contains | | public boolean contains(String name, String key)(Code) | | Does the specified mapped property contain a value for the specified
key value?
Parameters:
name - Name of the property to check
Parameters:
key - Name of the key to check true if the mapped property contains a value forthe specified key, otherwise false
exception:
IllegalArgumentException - if there is no propertyof the specified name |
| get | | public Object get(String name)(Code) | | Return the value of a simple property with the specified name.
Parameters:
name - Name of the property whose value is to be retrieved The property's value
exception:
IllegalArgumentException - if there is no propertyof the specified name |
| get | | public Object get(String name, int index)(Code) | | Return the value of an indexed property with the specified name.
Parameters:
name - Name of the property whose value is to be retrieved
Parameters:
index - Index of the value to be retrieved The indexed property's value
exception:
IllegalArgumentException - if there is no propertyof the specified name
exception:
IllegalArgumentException - if the specified propertyexists, but is not indexed
exception:
IndexOutOfBoundsException - if the specified indexis outside the range of the underlying property
exception:
NullPointerException - if no array or List has beeninitialized for this property |
| get | | public Object get(String name, String key)(Code) | | Return the value of a mapped property with the specified name,
or null if there is no value for the specified key.
Parameters:
name - Name of the property whose value is to be retrieved
Parameters:
key - Key of the value to be retrieved The mapped property's value
exception:
IllegalArgumentException - if there is no propertyof the specified name
exception:
IllegalArgumentException - if the specified propertyexists, but is not mapped |
| getDynaClass | | public DynaClass getDynaClass()(Code) | | Return the DynaClass instance that describes the set of
properties available for this DynaBean.
The associated DynaClass |
| getDynaProperty | | protected DynaProperty getDynaProperty(String name)(Code) | | Return the property descriptor for the specified property name.
Parameters:
name - Name of the property for which to retrieve the descriptor The property descriptor
exception:
IllegalArgumentException - if this is not a valid propertyname for our DynaClass |
| getMap | | public Map getMap()(Code) | | Return a Map representation of this DynaBean.
This, for example, could be used in JSTL in the following way to access
a DynaBean's fooProperty:
${myDynaBean.map.fooProperty}
a Map representation of this DynaBean |
| isAssignable | | protected boolean isAssignable(Class dest, Class source)(Code) | | Is an object of the source class assignable to the destination class?
Parameters:
dest - Destination class
Parameters:
source - Source class true if the source class is assignable to thedestination class, otherwise false |
| remove | | public void remove(String name, String key)(Code) | | Remove any existing value for the specified key on the
specified mapped property.
Parameters:
name - Name of the property for which a value is tobe removed
Parameters:
key - Key of the value to be removed
exception:
IllegalArgumentException - if there is no propertyof the specified name |
| set | | public void set(String name, Object value)(Code) | | Set the value of a simple property with the specified name.
Parameters:
name - Name of the property whose value is to be set
Parameters:
value - Value to which this property is to be set
exception:
ConversionException - if the specified value cannot beconverted to the type required for this property
exception:
IllegalArgumentException - if there is no propertyof the specified name
exception:
NullPointerException - if an attempt is made to set aprimitive property to null |
| set | | public void set(String name, int index, Object value)(Code) | | Set the value of an indexed property with the specified name.
Parameters:
