PropertyHandle :: Contains - Does property contain text
The function checks, whether the instance for the selected property handle contains the text passed in reg_string . The function returns true ( YES ), when the text has been found.
This version supports simple string expressions as "string", "*string", "string*" and "*string*". When not beginning or terminating the search string with an '*', the text must be at the beginning or at the end of a word. Searching for "string" will search for whole words, only.
In order to replace control sequences as '\n' or '\t' coded as character strings into corresponding control characters, conv_opt 1 has to be passed. For extracting plain text from HTML before checking, conv_opt 2 has to be passed. In order to perform both kind of conversions, conv_opt must be set to 3.
The function returns YES when the question was answered positively. Otherwise it returns NO .
Implementation details
When the instance is a structures instance, the function is called for all attributes and MEMO fields in the selected instance. Otherwise the data in the attribute or MEMO field is checked.
