Class DynaProperty
java.lang.Object
org.apache.commons.beanutils.DynaProperty
- Serializable
public class DynaProperty
extends java.lang.Object
implements Serializable
The metadata describing an individual property of a DynaBean.
The meta contains an
optional content type property (
getContentType()
)
for use by mapped and iterated properties.
A mapped or iterated property may choose to indicate the type it expects.
The DynaBean implementation may choose to enforce this type on its entries.
Alternatively, an implementatin may choose to ignore this property.
All keys for maps must be of type String so no meta data is needed for map keys.

DynaProperty(String name, Class type) - Construct a property of the specified data type.
|
DynaProperty(String name, Class type, Class contentType) - Construct an indexed or mapped
DynaProperty that supports (pseudo)-introspection
of the content type.

Construct an indexed or mapped DynaProperty
that supports (pseudo)-introspection
of the content type.

- Class that all indexed or mapped elements are instances of
getContentType
public Class getContentType()
Gets the
(optional) type of the indexed content for

's
that support this feature.
There are issues with serializing primitive class types on certain JVM versions
(including java 1.3).
Therefore, this field
must not be serialized using the standard methods.
- the Class for the content type if this is an indexed
DynaProperty
and this feature is supported. Otherwise null.
getName
public String getName()
Get the name of this property.
getType
public Class getType()
Gets the Java class representing the data type of the underlying property
values.

Please leave this field as transient
isIndexed
public boolean isIndexed()
Does this property represent an indexed value (ie an array or List)?
isMapped
public boolean isMapped()
Does this property represent a mapped value (ie a Map)?
