Method Detail

getBuildURL

public static java.lang.String getBuildURL(hudson.model.AbstractBuild<?,?> build)

Returns the full URL to the build details page for a given build.

getTestUrl

public static java.lang.String getTestUrl(hudson.tasks.test.TestResult result)

Returns the full URL to the test details page for a given test result;

extractCommandLine

public static java.lang.String[] extractCommandLine(java.lang.String message)

Parses a bot command from a given string. The 1st entry in the array contains the command name itself. The following entries contain the command parameters, if any.

copyOfRange

public static <T> T[] copyOfRange(T[] original,
                                  int from,
                                  int to)

Copies the specified range of the specified array into a new array. The initial index of the range (from) must lie between zero and original.length, inclusive. The value at original[from] is placed into the initial element of the copy (unless from == original.length or from == to). Values from subsequent elements in the original array are placed into subsequent elements in the copy. The final index of the range (to), which must be greater than or equal to from, may be greater than original.length, in which case (byte)0 is placed in all elements of the copy whose index is greater than or equal to original.length - from. The length of the returned array will be to - from.

Parameters:

original - the array from which a range is to be copied

from - the initial index of the range to be copied, inclusive

to - the final index of the range to be copied, exclusive. (This index may lie outside the array.)

Returns:

a new array containing the specified range from the original array, truncated or padded with zeros to obtain the required length

Throws:

java.lang.ArrayIndexOutOfBoundsException - if from < 0 or from > original.length()

java.lang.IllegalArgumentException - if from > to

java.lang.NullPointerException - if original is null Note: Unfortunately in Java 5 there is no Arrays#copyOfRange, yet. So we have to implement it ourself.

copyOf

public static <T> T[] copyOf(T[] original,
                             int newLength)

Copies the specified array, truncating or padding with nulls (if necessary) so the copy has the specified length. For all indices that are valid in both the original array and the copy, the two arrays will contain identical values. For any indices that are valid in the copy but not the original, the copy will contain null. Such indices will exist if and only if the specified length is greater than that of the original array.

Parameters:

original - the array to be copied

newLength - the length of the copy to be returned

Returns:

a copy of the original array, truncated or padded with nulls to obtain the specified length

Throws:

java.lang.NegativeArraySizeException - if newLength is negative

java.lang.NullPointerException - if original is null Note: copied from java 6

concat

public static <T> T[] concat(T[] array1,
                             T[]... arrays)

Returns a new array which a concatenation of the argument arrays.

join

public static java.lang.String join(java.lang.String[] array,
                                    int startIndex)

Joins together all strings in the array - starting at startIndex - by using a single space as separator.

getJoinedName

public static java.lang.String getJoinedName(java.lang.String[] args,
                                             int startIndex)

Extracts a name from an argument array starting at a start index and removing quoting ".

Parameters:

args - the arguments

startIndex - the start index

Returns:

the job name as a single String

Throws:

java.lang.IndexOutOfBoundsException - if startIndex > args length
