java.lang.Objectsim.util.Properties
The abstract superclass of Property inspectors. Such a beast inspects an object and returns a list of variables for which there are get and possibly set methods.
There are two such inspectors: SimpleProperties (inspects objects for their slots) and CollectionProperties (inspects Collections, Maps, and arrays for their contents). The easiest way to get an appropriate Properties subclass instance is to simply call the static method Properties.getProperties(object to inspect, .... ). See the SimpleProperties and CollectionProperties classes for

Method Summary | |
java.lang.String |
betterToString(java.lang.Object obj)
Call this to get a prettier print-name for an object -- converting arrays to a nicer format, for example. |
java.lang.Object |
getDomain(int index)
Returns the domain of the property at the given index. |
abstract java.lang.String |
getName(int index)
Returns the name of the property at the given index. |
static Properties |
getProperties(java.lang.Object object,
boolean expandCollections,
boolean includeSuperclasses,
boolean includeGetClass)
If expandCollections is true, then if object is a Map, Indexed, or Collection, then it will be treated using CollectionProperties. |
static Properties |
getProperties(java.lang.Object object,
boolean expandCollections,
boolean includeSuperclasses,
boolean includeGetClass,
boolean includeDomains)
|
abstract java.lang.Class |
getType(int index)
Returns the Class (or for primitive objects, the primitive TYPE) of the property at the given index. |
protected java.lang.Class |
getTypeConversion(java.lang.Class type)
|
abstract java.lang.Object |
getValue(int index)
Returns the value of the property at the given index. |
boolean |
isComposite(int index)
Returns true if the property at the given index is a "Composite" object, meaning it's not a primitive type (double, int, etc.) nor a String. |
abstract boolean |
isReadWrite(int index)
Returns true if the property at the given index is both readable and writable (as opposed to read-only). |
abstract boolean |
isVolatile()
Returns true if the number or order of properties could change at any time |
abstract int |
numProperties()
Returns the number of properties discovered in the object. |
java.lang.Object |
setValue(int index,
java.lang.Object value)
Sets the current value of the property. |
java.lang.Object |
setValue(int index,
java.lang.String value)
Sets the current value of the property to the value parsed from the given string. |
