Filter rows with a context value - value is an expression

[APIZZI1686753315]

Goal: build a data filter in context, and use the context value in a talend componant.

I use a context to create a filter expression. The value of context is correctly builded 

When I show the value  

System.out.println( " string : " + context.sSearchExpr ); 

Result : 

string : ( !( input_row.isIntern ) ) && ( !( input_row.isExternalEmail )

Now, how do use my context value in any talend componant( tFilterRow or tJavaRow)

Help me

Thanks.

Hello

It will not work. the filter expression will be treated as a string, however, the filter expression field requires a boolean value.

Shicong_Hong is correct.  It will be treated as a string.  But, in java you can convert a string into a statement, execute it.  From the web:  

String javaCode = "if (polishScreenHeight >= 200 && polishScreenHeight <= 235 && polishScreenWidth >= 220) { }";
// Convert the Java String to a Java statement
Statement statement = new Statement(null, javaCode, null);
// Execute the statement
statement.execute();

Can you provide me more insight on the use case?
