Java report tool finereport common functions usage Summary (Array Function), javafinereport

ADD2ARRAY

ADDARRAY (array, insertArray, start): inserts all elements in insertArray at the start position of the array and returns the array.

Example:

ADDARRAY ([3, 4, 1, 5, 7], [23, 43, 22], 3) Returns [3, 4, 23, 43, 22, 1, 5, 7].

ADDARRAY ([3, 4, 1, 5, 7], "test", 3) Returns [3, 4, "test", 1, 5, 7].

Note:

If start is less than 1 or the start parameter is not specified, array elements are inserted from the first part of the array by default.

 

ARRAY

ARRAY (arg1, arg2. ..): returns an ARRAY composed of arg1, arg2.

Arg1, arg2,...: string or number.

Example:

ARRAY ("hello") = ["hello"].

ARRAY ("hello", "world") = ["hello", "world"].

ARRAY ("hello", 98) = ["hello", 98].

ARRAY (67,98) = [67,98].

 

GETARRAYELEMENT

GETARRAYELEMENT (array, index): The function returns the index element of the array.

Example:

String [] array = {"a", "B", "c", "d "}

GETARRAYELEMENT (array, 3) equals to c.

GETARRAYELEMENT (array, 1) is equal to.

 

GREPARRAY

GREPARRAY (array, fn): The function (return true or false) is a condition. filter this array and form a new array.

Example:

GREPARRAY ([3, 4, 2, 3, 6, 8, 7], "item! = 3 ") equal to [, 7]

Note: The second parameter of this function is a string.

 

INARRAY

INARRAY (co, array): return the position of co in the array. If co is not in the array, 0 is returned.

Example:

String [] arr = {"a", "B", "c", "d "}

Then INARRAY ("B", arr) is equal to 2.

 

INDEX

INDEX (key, val1, val2,...): returns the position of the key in the sequence composed of val1, val2,.... If it does not exist in the sequence, it returns the number of parameters.

Note:

Key and valn can be of any type

Example:

INDEX (2, 2) is equal to 1.

INDEX (2, 1, 2) is equal to 2.

INDEX (2, 4, 5, 6) is 4.

INDEX ("B", "B", "o", "y") is equal to 1.

 

INDEXOFARRAY

INDEXOFARRAY (array, index): returns the index element of the array.

Example:

INDEXOFARRAY (["first", "second", "third"], 2) returns "second ".

 

MAPARRAY

MAPARRAY (array, fn): converts the items in an array to another array.

Array (Array): array to be converted

Fn (Function): functions used to process array projects

Example:

MAPARRAY ([3, 4, 2, 3, 6, 8, 7], "item! = 3 ") equal to [false, true, true, false, true].

 

RANGE

The RANGE (from, to, step) function indicates a sequence of numbers starting from integer from, taking step as an example of each step: until an integer.

Note:

The RANGE function has three parameters.

RANGE (to). The default value is from 1 and step 1.

RANGE (from, to). The default step is 1.

RANGE (from, to, step). For more information about the parameters, see the preceding annotations.

Example:

RANGE (4) Returns [1, 2, 4].

RANGE (-5) Returns [].

RANGE (-1, 3) Returns [-1, 0, 1, 2, 3].

RANGE () Returns [,].

RANGE (6,-1,-2) Returns [6, 4, 2, 0].

RANGE (4,1, 1) Returns [].

 

REMOVEARRAY

REMOVEARRAY (array, start, deleteCount): deletes the deleteCount array elements starting with the start element from the array and returns the deleted array.

Example:

REMOVEARRAY ([3, 4, 4, 2, 6, 7, 87], 4, 2) Returns [3, 4, 4, 7, 87].

 

REVERSEARRAY

REVERSEARRAY (array): returns the reverse array of the array.

Example:

REVERSEARRAY (["first", "second", "third"]) Returns ["third", "second", "first"].

 

SLICEARRAY

SLICEARRAY (array, start, end): returns the array from the start to the end (including the end element ).

Example:

SLICEARRAY ([3, 4, 5, 1, 5, 7], 3, 6) Returns [4, 5, 1, 5].

If the end parameter is not used, elements between start and end of the array are returned.

SLICEARRAY ([3, 4, 5, 1, 5, 7], 3) Returns [4, 5, 1, 5, 7].

 

SORTARRAY

SORTARRAY (array): returns an array in ascending order.

Example:

SORTARRAY ([3, 4, 5, 1, 5, 7]) Returns [1, 3, 4, 4, 5, 5, 7].

Note: The Element Types of the array must be the same and can be compared.

 

UNIQUEARRAY

UNIQUEARRAY (array): removes repeated elements from the array.

Example:

UNIQUEARRAY ([14,2, 3, 4, 3, 2, 5, 6, 2, 7, 9, 12, 3]) Returns [14, 2, 3, 4, 5, 6, 7, 9, 12].
