Method Detail

getSimpleName

public static java.lang.String getSimpleName(java.lang.Object element)

return a String representation of the element. It is "null", the content of a String or the simple class name for all other types.
Hint: Primitives wrapper classes are not handled specially, so the result is not the primitive value but the class name. But since getFieldValue(..) returns a String representation of primitives, this should not be a problem here.

Parameters:

element - the element

Returns:

the string representation

getNameToString

public static java.lang.String getNameToString(java.lang.Object element)

Null save toString

Parameters:

element - the element

Returns:

the string representation

checkFields

public static boolean checkFields(java.lang.Object element)

check if the element has member fields. For an array it checks if it is not empty.

Parameters:

element - the element

Returns:

yes or no

getFieldNames

public static java.util.List<java.lang.String> getFieldNames(java.lang.Object element)

returns a list of names of the fields. For an array it returns "[i]" as name where i is the position in the array.

Parameters:

element -

Returns:

getFieldValue

public static java.lang.Object getFieldValue(java.lang.Object object,
                                             java.lang.String name)

Returns the value of a field of an object.
For primitives it returns a string representation.
It returns null in case of any exceptions.

Parameters:

object - the questioned object

name - the name of the field

Returns:

the value
