                             Expression valueIfFalse)

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)

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

Returns:

could this expression be checked by the current implementation?

generateCode

public void generateCode(BlockScope currentScope,
                         CodeStream codeStream,

Code generation for the conditional operator ?:

Overrides:

Parameters:

currentScope - org.aspectj.org.eclipse.jdt.internal.compiler.lookup.BlockScope

codeStream - org.aspectj.org.eclipse.jdt.internal.compiler.codegen.CodeStream

valueRequired - boolean

generateOptimizedBoolean

public void generateOptimizedBoolean(BlockScope currentScope,
                                     CodeStream codeStream,

optimizedBooleanConstant

public Constant optimizedBooleanConstant()

Description copied from class: Expression

Constant usable for bytecode pattern optimizations, but cannot be inlined since it is not strictly equivalent to the definition of constant expressions. In particular, some side-effects may be required to occur (only the end value is known).

Overrides:

Returns:
