proguard.analysis.cpa.jvm.cfa.visitors.JvmIntraproceduralCfaFillerAllInstructionVisitor

所有已实现的接口:

AttributeVisitor

public class JvmIntraproceduralCfaFillerAllInstructionVisitor
extends Object
implements AttributeVisitor

This AttributeVisitor visits the CodeAttribute of a Method and performs two different tasks:

- for each exception handler (i.e. the beginning of a catch or finally block that can handle several ExceptionInfo) in the attribute exception table creates a JvmCatchCfaNode. Consecutive nodes may be linked with a false JvmAssumeExceptionCfaEdge (that indicates that the exception was not caught by a catch statement and is then passed to the following one) if the following catch block covers at least all the instruction offsets of the previous one (this includes also nested try/catch). If the exception is not caught by the last block of a chain an additional a false JvmAssumeExceptionCfaEdge to the exception exit block is added. This is not necessary for finally blocks (i.e. with exception type = 0) since they always re-throw the original exception once they're done, which will then be added as an edge to the first catch block that handles its offset by JvmIntraproceduralCfaFillerAllInstructionVisitor.JvmIntraproceduralCfaFillerVisitor.

- sets the parameters for the current method for a JvmIntraproceduralCfaFillerAllInstructionVisitor.JvmIntraproceduralCfaFillerVisitor and then acts similarly to an AllInstructionVisitor. The visitor visits all the instructions of the CodeAttribute and creates the CFA for the current method.
