Method Details

setProperty

public static void setProperty(Object target,
 String propertyName,
 Object propertyValue)
                        throws PropertyException

Set a direct or indirect property (dotted property: prop1.prop2.prop3) on the target object. This method tries to be smart in the way that intermediate properties currently set to null are set if it is possible to create and set an object. Conversions from propertyValue to the proper destination type are performed when possible.

Parameters:

target - the target object on which to set the property.

propertyName - the name of the property to set.

propertyValue - the value of the property to set.

Throws:

PropertyException - if an error happened while trying to set the property.

getProperties

public static Map getProperties(Object target)
                         throws PropertyException

Build a map of direct javabeans properties of the target object. Only read/write properties (ie: those who have both a getter and a setter) are returned.

Parameters:

target - the target object from which to get properties names.

Returns:

a Map of String with properties names as key and their values

Throws:

PropertyException - if an error happened while trying to get a property.

getProperty

public static Object getProperty(Object target,
 String propertyName)
                          throws PropertyException

Get a direct or indirect property (dotted property: prop1.prop2.prop3) on the target object.

Parameters:

target - the target object from which to get the property.

propertyName - the name of the property to get.

Returns:

the value of the specified property.

Throws:

PropertyException - if an error happened while trying to get the property.

setProperties

public static void setProperties(Object target,
 Map properties)
                          throws PropertyException

Set a Map of direct or indirect properties on the target object.

Parameters:

target - the target object on which to set the properties.

properties - a Map of String/Object pairs.

Throws:

PropertyException - if an error happened while trying to set a property.

propertiesToString

public static String propertiesToString(Object obj)

Return a comma-separated String of r/w properties of the specified object.

Parameters:

obj - the object to introspect.

Returns:

a a comma-separated String of r/w properties.
