BRules 1.2 Released on the Talend Exchange

There is a new version of BRules, a collection of Talend Routines, available on the Talend Exchange.  Version 1.2 includes new routines pad(), pad(size), and trimLeadingZeros().

pad()


pad() and pad(size) will add left padding to a string.  pad() without a size argument will pad to 10 characters.  Here are the test cases these routines support.

@Test
public void pad() {
   String[] a = {
    null,
    "",
    "a",
    "abc",
    "12345678901"
   };
   assertEquals(" ", BRules.pad(a[0]));
   assertEquals(" ", BRules.pad(a[1]));
   assertEquals(" a", BRules.pad(a[2]));
   assertEquals(" abc", BRules.pad(a[3]));
   assertEquals("12345678901", BRules.pad(a[4]));
}

@Test
public void padToSize() {
   String[] a = {
    null,
    "",
    "a",
    "abc",
    "12345678901"
   };
   assertEquals(" ", BRules.pad(a[0], 7));
   assertEquals(" ", BRules.pad(a[1], 7));
   assertEquals(" a", BRules.pad(a[2], 7));
   assertEquals(" abc", BRules.pad(a[3], 7));
   assertEquals("12345678901", BRules.pad(a[4], 7));
}

trimLeadingZeros()


trimLeadingZeros() removes the left leading zeros on a numeric string.  The function accepts and returns java.lang.String data.

Here is the test case that trimLeadingZeros() supports.

@Test
public void trimLeadingZeros() {
   String[] a = {
    null,
    "",
    "00101",
    "0",
    "999",
    "abc"
   };

   assertEquals("", BRules.trimLeadingZeros(a[0]));
   assertEquals("", BRules.trimLeadingZeros(a[1]));
   assertEquals("101", BRules.trimLeadingZeros(a[2]));
   assertEquals("0", BRules.trimLeadingZeros(a[3]));
   assertEquals("999", BRules.trimLeadingZeros(a[4]));
   assertEquals("abc", BRules.trimLeadingZeros(a[5]));
}
