findBeanMethod(java.lang.Class<?> cls,
java.lang.String baseName)
Deprecated.
Given a bean class and a base method name, this method will try to find a public method without parameters that is named:
baseName
get + BaseName
is + BaseName

static java.util.Collection<java.lang.Object> |
fromIterator(java.util.Iterator<java.lang.Object> iterator)

Given an
iterator , this method will return a Collection . |
static java.lang.Object |
getField(java.lang.Object object,
java.lang.String fieldName)
Deprecated.
Given an
object , this method will return the value of the public field identified by fieldName . |

object (i.e. |
static java.lang.Object |
invokeBeanMethod(java.lang.Object object,
java.lang.String methodName)
Deprecated.
Given a bean
object , this method will invoke the public method without parameters identified by methodName and
return the invocation's result. |
static boolean |
isMethodAllowed(java.lang.reflect.Method method)
Deprecated.
Returns
true if the method is not one of the Object 's class declared methods, with the exception of
Object.toString() . |
static boolean |
isPrimitive(java.lang.Object object)
Deprecated.
Checks if the provided
object is an instance of a primitive class. |

resolveProperty(java.lang.Object target,
java.lang.Object property)
Deprecated.
Given the
target object, this method attempts to resolve and return the value of the passed property . |
static boolean |
toBoolean(java.lang.Object object)
Deprecated.
Converts the given
object to a boolean value, applying the following rules:
if the object is null the returned value is false
if the object is a Number the method will return false only if the number's value is 0
if the String representation of the object is equal irrespective of its casing to "true", the method will
return true
if the object is a Collection or a Map , the method will return true only if the collection /
map is not empty
if the object is an array, the method will return true only if the array is not empty
|
static java.util.Collection<java.lang.Object> |
toCollection(java.lang.Object object)
Deprecated.
Forces the conversion of the passed
object to a collection, according to the following rules:
if the object is null an empty collection will be returned
if the object is an array a list transformation of the array will be returned
if the object is a Collection the object itself will be returned
if the object is an instance of a Map the map's key set will be returned (see Map.keySet() )
if the object is an instance of an Enumeration a list transformation will be returned
if the object is an instance of an Iterator or Iterable the result of fromIterator(Iterator)
will be returned
if the object is an instance of a String or Number a Collection containing only this
object will be returned
any other case not covered by the previous rules will result in an empty Collection
|
static java.lang.Number |
toNumber(java.lang.Object object)
Deprecated.
Coerces the passed
object to a numeric value. |

otherwisepublic static java.lang.Object resolveProperty(java.lang.Object target, java.lang.Object property)
Given the target
object, this method attempts to resolve and return the value of the passed property
.
The property can be either an index or a name:
target
will be assumed to be either an array or it will be converted to a Collection
; a fallback to Map
will be
made in case the previous two attempts failed
property
will be converted to a String
(see toString(Object)
); the target
will be assumed to be either a Map
or an object; if the Map
attempt fails, the property
will be
used to check if the target
has a publicly accessible field with this name or a publicly accessible method with no
parameters with this name or a combination of the "get" or "is" prefixes plus the capitalised name (see
