                        int ttlForFieldCheck)

Description copied from class: Expression

Check this expression against potential NPEs, which may occur:

• if the expression is the receiver in a field access, qualified allocation, array reference or message send incl. implicit message sends like it happens for the collection in a foreach statement.

• if the expression is the exception in a throw statement

If a risk of NPE is detected report it to the context. If the expression denotes a local variable, mark it as checked, which affects the flow info.

Overrides:

checkNPE in class Reference

Parameters:

scope - the scope of the analysis

flowContext - the current flow context
