MDM routine

Availability-noteDeprecated

The table below lists some useful MDM routine functions including those for mangling foreign keys. In MDM, you usually need to mangle foreign keys to accommodate to compound keys.

Useful MDM routine functions
Function Description Syntax
getFK Returns one of the foreign key components by position in a mangled foreign key.

Note that the position is specified by an integer starting from 0.

 MDM.getFK

For example:

getFK("[fk1][fk2][fk3]",1),

which will return the second foreign key component in the composite foreign key. The output message will be "fk2".
getWSClientTimeout Gets webservice client timeout information from jvm param setting. MDM.getWSClientTimeout(String property)
createFK Returns the foreign key string by a single key (String singleKey). MDM.createFK

For example:

createFK("0"),

which will return a foreign key created with the id provided. The output message will be "[0]".
createFK Returns the foreign key string by a key list (String[] keys). MDM.createFK

For example:

createFK({"0","1"}),

which will return a foreign key with the ids provided. The output message will be "[0][1]".
createReturnMessage Generates an error message with the content of msg and error code of code. MDM.createReturnMessage(String msg, int code)
createReturnMessage Generates a report message with the content of msg and type of type. MDM.createReturnMessage(String msg, String type)
getRepeatingElement Gets repeating element in an XML string according to the xpath and position.

Note that the position is specified by an integer starting from 0.

 MDM.getRepeatingElement

For example:

getRepeatingElement("<Product><Features><Feature>color</Feature><Feature>size</Feature></Features></Product>","/Product/Features/Feature",1),

which will extract the second multi-occurrence element described by the xpath node from the XML string provided. The output message will be "size".
hasRepeatingElement Checks repeating elements in an XML string according to the xpath and the text. MDM.hasRepeatingElement

For example:

hasRepeatingElement("<Product><Features><Feature>color</Feature><Feature>size</Feature></Features></Product>","/Product/Features/Feature","size"),

which will return the result about whether the specified multi-occurrence element described by the xpath node and the text "size" exist in the XML string provided. The output message will be "true".
listRepeatingElement Lists repeating elements in an XML string according to the xpath and the delimiter.

Note that the delimiter is wrapped by single quotes.

 MDM.listRepeatingElement

For example:

listRepeatingElement("<Product><Features><Feature>color</Feature><Feature>size</Feature></Features></Product>", "/Product/Features/Feature",',') ,

which will list all the multi-occurrence elements described by the xpath node from the XML string provided with the specified delimiter. The output message will be "color, size".
addRepeatingElement Adds repeating elements in an XML string according to the xpath and the text. MDM.addRepeatingElement

For example:

addRepeatingElement("<Product><Features><Feature>color</Feature><Feature>size</Feature></Features></Product>", "/Product/Features/Feature","model"),

which will add a new multi-occurence element described by the combination of the xpath node and the text to the XML string provided. The output message will be
<Product>
    <Features>
        <Feature>color</Feature>
        <Feature>size</Feature>
        <Feature>model</Feature>
    </Features>
</Product>
.
setLanguageVariant Adds or updates an ISO variant to the multilingual text value. MDM.setLanguageVariant

For example:

setLanguageVariant("EN","abc","[EN:ab][FR:ab_fr]"),

which will update the EN variant to be "abc". The output message will be [EN:abc][FR:ab_fr].
setLanguageVariant Adds or updates an ISO variant to the multilingual text value with the default ISO and the sort option for the output message.

If the sort option is set to "true", the message will be output in alphabetical order.

 MDM.setLanguageVariant

For example:

setLanguageVariant("FR","ab_fr","ab","EN", true), which will add the FR variant "ab_fr". The output message will be [EN:ab][FR:ab_fr].
getLanguageVariant Gets an ISO value from a multilingual text value with the default ISO fallback.

If the ISO value requested is not found, the default ISO value will be returned.

 MDM.getLanguageVariant

For example:

getLanguageVariant("DE","EN","[EN:ab][FR:ab_fr]"), which will return the default EN value "ab" because the DE value requested is not found.
getLanguageVariant Gets an ISO value from a multilingual text value.

If the ISO value requested is not found, the null value will be returned.

 MDM.getLanguageVariant

For example:

getLanguageVariant("FR","[EN:ab][FR:ab_fr]"), which will return the requested FR value "ab_fr".
