checkNPE

public boolean checkNPE(BlockScope scope,
 FlowContext flowContext,
 FlowInfo flowInfo,
 int ttlForFieldCheck)

Beschreibung aus Klasse kopiert: 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 subject to unboxing
• 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.

checkNPE in Klasse Expression

Parameter:

scope - the scope of the analysis

flowContext - the current flow context

flowInfo - the upstream flow info; caveat: may get modified

ttlForFieldCheck - if this is a reference to a field we will mark that field as nonnull for the specified timeToLive

Gibt zurück:
