public class DynaProperty extends Object implements Serializable
The metadata describing an individual property of a DynaBean.
The meta contains an optional content type property (DynaProperty) 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.

Constructor Summary | |
---|---|
DynaProperty(String name)
Construct a property that accepts any data type.
| |
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.
|
Method Summary | |
---|---|
boolean | equals(Object obj)
Checks this instance against the specified Object for equality. |
Class | getContentType()
Gets the (optional) type of the indexed content for DynaProperty 's
that support this feature.
|
String | getName()
Get the name of this property. |
Class | getType() Gets the Java class representing the data type of the underlying property values. There are issues with serializing primitive class types on certain JVM versions (including java 1.3). |
int | hashCode() |
boolean | isIndexed()
Does this property represent an indexed value (ie an array or List)?
|
boolean | isMapped()
Does this property represent a mapped value (ie a Map)?
|
String | toString()
Return a String representation of this Object. |

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.
Returns: the Class for the content type if this is an indexed DynaProperty
