Class InnerAssignmentCheck

Checks for assignments in subexpressions, such as in String s = Integer.toString(i = 2);.

Rationale: With the exception of for iterators, all assignments should occur in their own toplevel statement to increase readability. With inner assignments like the above it is difficult to see all places where a variable is set.

By default the check will check the following assignment operators: ASSIGN, BAND_ASSIGN, BOR_ASSIGN, BSR_ASSIGN, BXOR_ASSIGN, DIV_ASSIGN, MINUS_ASSIGN, MOD_ASSIGN, PLUS_ASSIGN, SL_ASSIGN, SR_ASSIGN, STAR_ASSIGN.

An example of how to configure the check is:

 <module name="InnerAssignment"/>
 

An example of how to configure the check for only =, +=, and -= operators is:

 <module name="InnerAssignment">
    <tokens>ASSIGN, PLUS_ASSIGN, MINUS_ASSIGN</tokens>
 </module>
