static boolean cern.gp.util.ArrayUtil.allElementsSameType

(

Object[]

array

)

[static]

An utility method that checks whether all the elements in the array are of the same type it returns false if the array contains a mix of classes and sub-classes of the Array component type.

Parameters:

array

the array to be checked

Returns:

true if all array elements are of the same class

static Object cern.gp.util.ArrayUtil.concatArrays	(	final Object[]	one,
		final Object[]	two,
		Class	componentType
	)			[static]

An utility method that concatenates two arrays to one

Parameters:

	one	the first array
	two	the second array
	componentType	the class of the component of the array to be returned

Returns:

an array of type componentType with the concatenation of the two arrays

static Object cern.gp.util.ArrayUtil.concatArrays	(	final Object[]	one,
		final Object[]	two,
		final Object[]	three,
		Class	componentType
	)			[static]

An utility method that concatenates three arrays to one

Parameters:

	one	the first array
	two	the second array
	three	the third array
	componentType	the class of the component of the array to be returned

Returns:

an array of type componentType with the concatenation of the two arrays

static Object cern.gp.util.ArrayUtil.concatArrays	(	final Object	origMatrix[][],
		final int	totalLength
	)			[static]

An utility method that concatenates many arrays to one. The type of the returned array are derived from the type of the origMatrix parameter, the length is specified.

Parameters:

	origMatrix	an array of arrays (a Matrix), can contain null elements
	totalLength	the length of the resulting array, must be large enough

Returns:

an array with the concatenated values

static Object cern.gp.util.ArrayUtil.concatArrays

(

final Object

origMatrix[][]

)

[static]

An utility method that concatenates many arrays to one. The type and the length of the returned array are derived from the type of the origMatrix parameter

Parameters:

origMatrix

an array of arrays (a Matrix)

Returns:

an array with the concatenated values

static void cern.gp.util.ArrayUtil.printArray	(	final Object[]	array,
		int	indent
	)			[static]

utility method, prints out an array using the toString() method of the members.

Parameters:

	array	can be null
	indent	the level of indents (tabs) that precede the output, can be negative

static Object cern.gp.util.ArrayUtil.pruneNullElements	(	Object[]	array,
		boolean	onlyAtEnd
	)			[static]

prunes the null elements at the tail of an array. In the present implementation, onlyAtEnd must be true

Parameters:

	array	the array to be pruned
	onlyAtEnd	-- must be true

static Object cern.gp.util.ArrayUtil.pruneNullElements

(

Object[]

array

)

[static]

A utility method that cuts off null-elements at the end of an array.

Returns:

a new array with only the non-null elements and the corresponding length

static void cern.gp.util.ArrayUtil.sleep

(

long

millis

)

[static]

Utility method, sleeps for the indicated millis. Useful because it can be called in user programs without need to code the try/catch clauses.

Parameters:

millis

the milliseconds to sleep

static String cern.gp.util.ArrayUtil.toString	(	final Object[]	array,
		int	indent,
		boolean	oneLine,
		boolean	numbered
	)			[static]

utility method, transforms the array into a String that can either be multi-line or on one line.

Parameters:

	array	the array to be transformed, can be null
	indent	the number of tabs to be used for indenting
	oneLine	if true, a String containing a single line is returned, if false, return characters ("\n") are integrated into the returned string.
	numbered	if true, each element is preceded by its index in the array

Returns:

a string with the array contents, formated as requested
