how can i convert a string to boolean

[Former Member]

hai,

iam in need of converting a " string set" in a idoc to a boolean type . is there any simple procedure in graphical mapping to do this ?

Hi Vivek,

You want to convert to boolean to check it in a condition?

e.g,., if (StringSet)

swapna,

the boolean type is the final o/p type and its not used for any other condition checking or other purpose ...

Hi Vivek,

If your requirement is just to map string value (containing true or false as values) to a output field of type boolean.

In Graphical Mapping, just map the source field directly to target field.No Conversion is needed and it works.

Stringvalue -> TargetField

Thanks,

Swapna.

thanks for the answer but in real time scenarios , if in case the user gives yes / no then it may lead to problems . so i think it would be better to use theudf itself

Hi Vivek,

From your query, I was of the impression that you are getting true or false as values and you need to convert to boolean.

If it is a real-time scenario with users having an opton to enter their text, then even to use a UDF, you need to know what all are the possible ways the user can send a true value (true, yes, correct,right).A little fast then may be even just 'S' :).

And just one info Boolean.parseBoolean(strName); it does return boolean value, but for UDF the return type is String, so you do not need this. You just have to get the list of possible values and then say

if(String.equalsIgnoreCase("true") || String.equalsIgnoreCase("yes") )

{

return "true";

}

or may be even value-mapping.

Thanks,

Swapna.

In UDF of graphical mapping, u may use the following code:

String strName = "true";

Boolean bool=new Boolean(strName);

boolean b=bool.booleanValue();

OR

boolean b = Boolean.parseBoolean(strName);

System.out.println (b);

Well you can use a java code to achieve the same, but I am not sure as to what exactly your requirement is. The reason being the UDF will eventually output a string only.

String str;

boolean b;

b=Boolean.parseBoolean(str);

// Do your validations with b and then finally return a string

String finalStr = new Boolean(b).toString();
