Parameters:

writer -

formName -

dummyFormParams -

formTarget -

Throws:

java.io.IOException

getClearHiddenCommandFormParamsFunctionName

public java.lang.String getClearHiddenCommandFormParamsFunctionName(java.lang.String formName)

Prefixes the given String with "clear_" and removes special characters

Parameters:

formName -

Returns:

String
