Method Detail

getArrayClass

public static java.lang.Class getArrayClass(java.lang.Class c)

Returns the basic class of an array class (handles multi-dimensional arrays).

Parameters:

c - the array to inspect

Returns:

the class of the innermost elements

getArrayDimensions

public static int getArrayDimensions(java.lang.Class array)

Returns the dimensions of the given array. Even though the parameter is of type "Object" one can hand over primitve arrays, e.g. int[3] or double[2][4].

Parameters:

array - the array to determine the dimensions for

Returns:

the dimensions of the array

getArrayDimensions

public static int getArrayDimensions(java.lang.Object array)

Returns the dimensions of the given array. Even though the parameter is of type "Object" one can hand over primitve arrays, e.g. int[3] or double[2][4].

Parameters:

array - the array to determine the dimensions for

Returns:

the dimensions of the array

arrayToString

public static java.lang.String arrayToString(java.lang.Object array,
                                             boolean outputClass)

Returns the given Array in a string representation. Even though the parameter is of type "Object" one can hand over primitve arrays, e.g. int[3] or double[2][4].

Parameters:

array - the array to return in a string representation

outputClass - whether to output the class name instead of calling the object's "toString()" method

Returns:

the array as string

arrayToString

public static java.lang.String arrayToString(java.lang.Object array)

Returns the given Array in a string representation. Even though the parameter is of type "Object" one can hand over primitve arrays, e.g. int[3] or double[2][4].

Parameters:

array - the array to return in a string representation

Returns:

the array as string

flatten

public static java.lang.String flatten(java.util.List lines,
                                       java.lang.String sep)

Flattens the list into a single, long string. The separator string gets added between the objects, but not after the last one.

Parameters:

lines - the lines to flatten

sep - the separator

Returns:

the generated string

flatten

public static java.lang.String flatten(java.lang.Object[] lines,
                                       java.lang.String sep)

Flattens the array into a single, long string. The separator string gets added between the objects, but not after the last one. Uses the "toString()" method of the objects to turn them into a string.

Parameters:

lines - the lines to flatten

sep - the separator

Returns:

the generated string
