public void recordFlowUpdateOnResult(LocalVariableBinding local,
 boolean nonNullIfTrue,
 boolean negatable)

updateFlowOnBooleanResult

protected void updateFlowOnBooleanResult(FlowInfo flowInfo,
 boolean result)

Description copied from class: Expression

Back-propagation of flow info: before analysing a branch where a given condition is known to hold true/false respectively, ask the condition to contribute its information to the given flowInfo.

Overrides:

updateFlowOnBooleanResult in class Expression

Parameters:

flowInfo - the info to be used for analysing the branch

result - condition result that would cause entering the branch

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?

computeConversion

 TypeBinding compileTimeType)

Description copied from class: Expression

Base types need that the widening is explicitly done by the compiler using some bytecode like i2f. Also check unsafe type operations.

Overrides:

computeConversion in class Expression

Parameters:

scope - a scope

runtimeTimeType - this is the type required at runtime

compileTimeType - this is what the compiler knows about the provided value
