Method Detail

analyseCode

public FlowInfo analyseCode(BlockScope currentScope,
                            FlowContext flowContext,
                            FlowInfo flowInfo)

Overrides:

analyseCode in class Expression

checkNPE

public boolean checkNPE(BlockScope scope,
                        FlowContext flowContext,
                        FlowInfo flowInfo,
                        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 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.

Overrides:

checkNPE in class Expression

Parameters:

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

Returns:

could this expression be checked by the current implementation?
