Conversion Functions

 Top Previous Topic Next Topic  Print this topic

Conversion functions are functions that convert the data type of an input value into another data type.

The supported conversion functions are convert-to-number-function, convert-to-bool-function and convert-to-string-function.

 

•<das:convert-to-number-function> - converts bool or number values into number values: "true" converts into "1" and "false" converts into "0".

The sample below describes the syntax of the convert-to-number-function.

 

 

<das:convert-to-number-function id="11">

       <das:in-param id="13" name="string" src="34"/>

       <das:return-value id="12"/>

</das:convert-to-number-function>

 

 

Attributes:

id - unique identifier of this resource in the current processing job.

 

Children elements:

<das:return-value> - specifies the id from which the result value of the function will be referenced in the current job.

<das:in-param> - specifies the source and name of the function parameter.

 

 

•<das:convert-to-bool-function> - converts all data types into bool values.

Every number other than "0" converts into "true" and "0" converts into "false".

String values different than "true" convert into "false".

The sample below describes the syntax of the convert-to-bool-function.

 

 

<das:convert-to-bool-function id="20">

       <das:in-param id="22" name="string" src="13"/>

       <das:return-value id="21"/>

</das:convert-to-bool-function>

 

 

Attributes:

id - unique identifier of this resource in the current processing job.

 

Children elements:

<das:return-value> - specifies the id from which the result value of the function will be referenced in the current job.

<das:in-param> - specifies the source and name of the function parameter.

 

 

•<das: convert-to-string-function> converts all data types into string values.

The sample below describes the syntax of the convert-to-string-function.

 

 

<das:convert-to-string-function id="19">

       <das:in-param id="21" name="string" src="17"/>

       <das:return-value id="20"/>

</das:convert-to-string-function>

 

 

Attributes:

id - unique identifier of this resource in the current processing job.

 

Children elements:

<das:return-value> - specifies the id from which the result value of the function will be referenced in the current job.

<das:in-param> - specifies the source and name of the function parameter.
