构造器详细资料

InitializationFinder

public InitializationFinder()

Creates a new InitializationFinder.

InitializationFinder

public InitializationFinder(PartialEvaluator partialEvaluator,
 boolean runPartialEvaluator)

Creates a new InitializationFinder that will use the given partial evaluator.

参数:

partialEvaluator - the evaluator to be used for the analysis.

runPartialEvaluator - specifies whether to run this evaluator on every code attribute that is visited.

方法详细资料

isInitializer

public boolean isInitializer()

Returns whether the method is an instance initializer, in the CodeAttribute that was visited most recently.

superInitializationOffset

public int superInitializationOffset()

Returns the instruction offset at which this initializer is calling the "super" or "this" initializer method, or NONE if it is not an initializer.

creationOffset

public int creationOffset(int initializationOffset)

Returns the 'new' instruction offset at which the object instance is created that is initialized at the given offset.

isInitializedBefore

public boolean isInitializedBefore(int offset,
 int stackEntryIndexBottom)

Returns whether the specified stack entry is initialized.

isTopInitializedBefore

public boolean isTopInitializedBefore(int offset,
 int stackEntryIndexTop)

Returns whether the specified stack entry is initialized.

isInitializedBefore

public boolean isInitializedBefore(int offset,
 InstructionOffsetValue creationOffsetValue)

Returns whether the given creation offset is initialized before the given offset.

isInitializer

public boolean isInitializer(int offset)

Returns whether the instruction at the given offset is the special invocation of an instance initializer.

visitAnyAttribute

public void visitAnyAttribute(Clazz clazz,
 Attribute attribute)

从接口复制的说明: AttributeVisitor

Visits any Attribute instance. The more specific default implementations of this interface delegate to this method.

指定者:

visitCodeAttribute

public void visitCodeAttribute(Clazz clazz,
 Method method,
 CodeAttribute codeAttribute)

指定者:
