One step closer to finishing this BizTalk Mapper Extensions Utility Pack project migration. Today, we will focus on another set of libraries available for BizTalk Server 2020: String Functoids.
📝 One-Minute Brief
Introduces the String Functoids in the BizTalk Mapper Extensions UtilityPack for BizTalk Server 2020, providing a rich set of functoids to create, transform, compare, and normalize strings directly inside BizTalk maps.
String Functoids
This library includes a suite of functoids that provide many methods for safely creating, manipulating, and comparing strings that you can use inside the BizTalk mapper.
This project includes the following Custom Functoids:
String Constant functoid
This functoid allows you to set constant values (strings) inside the maps.
- The functoid takes one mandatory input parameter:
- String value to return out
- The output of the functoid is the string set in the output. Example: P0011
String ToTitleCase functoid
This functoid allows you to convert the specified string to title case (except for words that are entirely in uppercase, which are considered to be acronyms)
- The functoid takes one mandatory input parameter:
- The string to convert to title case
- The output of the functoid is a string converted to title case. Example: Sandro Augusto Sousa Pereira
String Advance Compare Functoid
This functoid allows you to compare two specified String objects, ignoring or honoring their case, and returns a boolean that indicates if they are equal or not.
- The functoid takes three mandatory input parameters:
- The first string to compare
- The second string to compare
- A boolean value: set True to ignore case during the comparison; otherwise, False.
- The output of the functoid is a Boolean that indicates if they are equal or not. Example: True
String Replace Functoid
This functoid returns a new string in which all occurrences of a specified string (second parameter) found in the first string are replaced with another specified string (third parameter).
- The functoid takes three mandatory input parameters:
- A string where we will replace the values
- A string to be replaced.
- A string to replace all occurrences of oldValue.
- The output of the functoid is a string that is equivalent to the current string except that all instances of oldValue are replaced with newValue. If oldValue is not found in the current instance, the method returns the current instance unchanged. Example: Sandro Pereira: BizTalk
String Normalize Functoid
This functoid allows you to normalize the text. It will remove two or more consecutive spaces and replace them with a single space, remove two or more consecutive newlines and replace them with a single newline, and condense multiple tabs into one.
- The functoid takes one mandatory input parameter:
- The string to normalize
- The output of the functoid is a string normalized without consecutive spaces, lines, or tabs. Example: Sandro Augusto
Sousa Pereira
String PadLeft Functoid
This functoid allows you to set a new string that right-aligns the characters in this instance by padding them on the left with a specified Unicode character, for a specified total length.
- The functoid takes three mandatory input parameters:
- A string that will be a pad on the left with a specified Unicode character
- The number of characters in the resulting string is equal to the number of original characters plus any additional
padding characters. - A Unicode padding character.
- The output of the functoid is a new string that is equivalent to this instance, but right-aligned and padded on the left with as many paddingChar characters as needed to create a length of totalWidth. However, if totalWidth is less than the length of this instance, the method returns a reference to the existing instance. If totalWidth is equal to the length of this instance, the method returns a new string that is identical to this instance. Example: *BTS
String PadRight Functoid
This functoid allows you to set a new string that left-aligns the characters in this string by padding them on the right with a specified Unicode character, for a specified total length.
- The functoid takes three mandatory input parameters:
- A string that will be a pad on the right with a specified Unicode character
- The number of characters in the resulting string is equal to the number of original characters plus any additional
padding characters. - A Unicode padding character.
- The output of the functoid is a new string that is equivalent to this instance, but left-aligned and padded on the right with as many paddingChar characters as needed to create a length of totalWidth. However, if totalWidth is less than the length of this instance, the method returns a reference to the existing instance. If totalWidth is equal to the length of this instance, the method returns a new string that is identical to this instance. Example: BTS*
String Remove Leading Zeros Functoid
This functoid allows you to remove any leading zeros from an input string.
- The functoid has one mandatory parameter:
- Input string that may contain leading zeros that need to be removed.
- The output of the functoid is an integer that is equal to the input instance but with the leading zeros removed.
BizTalk Mapper Extensions Utility Pack
BizTalk Mapper Extensions Utility Pack is a set of libraries that includes several useful functoids to include in a map, extending BizTalk Mapper’s capabilities.
