Class BasicDynaBean
java.lang.Object
org.apache.commons.beanutils2.BasicDynaBean
- All Implemented Interfaces:
- DynaBean
 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.

Method Details- 
containsDoes the specified mapped property contain a value for the specified key value?- Specified by:
- containsin interface- DynaBean
- Parameters:
- name- Name of the property to check
- key- Name of the key to check
- Returns:
- trueif the mapped property contains a value for the specified key, otherwise- false
- Throws:
- IllegalArgumentException- if there is no property of the specified name
 
- 
getGets the value of a simple property with the specified name.- Specified by:
- getin interface- DynaBean
- Parameters:
- name- Name of the property whose value is to be retrieved
- Returns:
- The property's value
- Throws:
- IllegalArgumentException- if there is no property of the specified name
 
- 
getGets the value of an indexed property with the specified name.- Specified by:
- getin interface- DynaBean
- Parameters:
- name- Name of the property whose value is to be retrieved
- index- Index of the value to be retrieved
- Returns:
- The indexed property's value
- Throws:
- IllegalArgumentException- if there is no property of the specified name
- IllegalArgumentException- if the specified property exists, but is not indexed
- IndexOutOfBoundsException- if the specified index is outside the range of the underlying property
- NullPointerException- if no array or List has been initialized for this property
 
- 
getGets the value of a mapped property with the specified name, ornullif there is no value for the specified key.- Specified by:
- getin interface- DynaBean
- Parameters:
- name- Name of the property whose value is to be retrieved
- key- Key of the value to be retrieved
- Returns:
- The mapped property's value

- 
getDynaClassGets theDynaClassinstance that describes the set of properties available for this DynaBean.- Specified by:
- getDynaClassin interface- DynaBean
- Returns:
- The associated DynaClass
 
- 
getDynaPropertyGets the property descriptor for the specified property name.- Parameters:
- name- Name of the property for which to retrieve the descriptor
- Returns:
- The property descriptor
- Throws:
- IllegalArgumentException- if this is not a valid property name for our DynaClass
 
- 
getMapGets 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.<strong>map</strong>.fooProperty}
 - Returns:

- 
setSets the value of an indexed property with the specified name.- Specified by:
- setin interface- DynaBean
- Parameters:
- name- Name of the property whose value is to be set
- index- Index of the property to be set
- value- Value to which this property is to be set
- Throws:
