Method Detail

retrieveAllFieldsFromClass

public static java.util.List<java.lang.reflect.Field> retrieveAllFieldsFromClass(java.lang.Class<?> clazz)

This static method returns all the fields from a class including those inherited.

Parameters:

clazz - a Class object

Returns:

a List of Field instances

isPrimitive

public static boolean isPrimitive(java.lang.Class<?> clazz)

This method returns true if the class is primitive or a wrapper for a primitive.

Parameters:

clazz -

Returns:

a boolean

getDimensions

public static int[] getDimensions(java.lang.Object[] array)

This method returns the dimensions of an array. The array is assumed to be consistent, ie. the row lengths do not change across the row.

Parameters:

array - an array

Returns:

an array of integer

convertArrayType

public static java.lang.Object convertArrayType(java.lang.Object[] currentArray,
                                                java.lang.Class<?> clazz)

This method is used to convert an array of particular class into an array of another class. Typically, it could be used to convert an array of Object into an array of double if all the elements of the original array are instances of double.

Parameters:

currentArray -

clazz -

Returns:

an Object
