Constructor Details

InvokeDynamicInstruction

public InvokeDynamicInstruction(short opcode,
 BootstrapMethodsReader.BootstrapMethod bootstrap,
 String methodName,
 String methodType)

Method Details

isPEI

public boolean isPEI()

Description copied from interface: IInstruction

PEI == "Potentially excepting instruction"

Specified by:

isPEI in interface IInstruction

Returns:

true iff this instruction might throw an exception

getInvocationCode

public IInvokeInstruction.Dispatch getInvocationCode()

Specified by:

getInvocationCode in interface IInvokeInstruction

Returns:

one of BytecodeConstants.INVOKE[SPECIAL|VIRTUAL|STATIC|INTERFACE]

getPoppedCount

public final int getPoppedCount()

Specified by:

getPoppedCount in interface IInstruction

Overrides:

getPoppedCount in class Instruction

Returns:

the number of values this instruction pops off the working stack

getPushedType

public final String getPushedType(String[] types)

Description copied from class: Instruction

Computes the type of data pushed onto the stack, or null if none is pushed.

Specified by:

getPushedType in interface IInstruction

Overrides:

getPushedType in class Instruction

Parameters:

types - the types of the data popped off the stack by this instruction; if poppedTypes is null, then we don't know the incoming stack types and the result of this method may be less accurate

getPushedWordSize

public final byte getPushedWordSize()

Specified by:

getPushedWordSize in interface IInstruction

Overrides:

getPushedWordSize in class Instruction

Returns:

the JVM word size of the value this instruction pushes onto the stack, or 0 if this instruction doesn't push anything onto the stack.

getBootstrap

public BootstrapMethodsReader.BootstrapMethod getBootstrap()

getMethodSignature

public String getMethodSignature()

Specified by:

getMethodSignature in interface IInvokeInstruction

getMethodName

public String getMethodName()

Specified by:

getMethodName in interface IInvokeInstruction

getClassType

public String getClassType()

Specified by:

getClassType in interface IInvokeInstruction

visit

public void visit(IInstruction.Visitor v)

Description copied from class: Instruction

Apply a Visitor to this instruction. We invoke the appropriate Visitor method according to the type of this instruction.

Specified by:

visit in interface IInstruction

Specified by:

visit in class Instruction

toString

public String toString()

Description copied from class: Instruction

Subclasses must implement toString.

Specified by:

toString in interface IInstruction

Specified by:

toString in class Instruction
