public class INVOKEDYNAMIC
extends InvokeInstruction

Class for INVOKEDYNAMIC. Not an instance of InvokeInstruction, since that class expects to be able to get the class of the method. Ignores the bootstrap mechanism entirely.

Since:

6.0

Method Summary

Modifier and Type	Method	Description
void	accept(Visitor v)	Call corresponding visitor method(s).
void	dump(DataOutputStream out)	Dump instruction as byte code to stream out.
String	getClassName(ConstantPoolGen cpg)	Override the parent method because our classname is held elsewhere.
Class<?>[]	getExceptions()
ReferenceType	getReferenceType(ConstantPoolGen cpg)	Since InvokeDynamic doesn't refer to a reference type, just return java.lang.Object, as that is the only type we can say for sure the reference will be.
protected void	initFromFile(ByteSequence bytes, boolean wide)	Read needed data (i.e., index) from file.

INVOKEDYNAMIC

public INVOKEDYNAMIC(int index)

Method Detail

dump

public void dump(DataOutputStream out)
          throws IOException

Dump instruction as byte code to stream out.

Overrides:

dump in class CPInstruction

Parameters:

out - Output stream

Throws:

IOException

initFromFile

protected void initFromFile(ByteSequence bytes,
                            boolean wide)
                     throws IOException

Read needed data (i.e., index) from file.

Overrides:

initFromFile in class CPInstruction

Parameters:

bytes - input stream

wide - wide prefix?

Throws:

IOException - may be thrown if the implementation needs to read data from the file

toString

public String toString(ConstantPool cp)

Overrides:

toString in class InvokeInstruction

Returns:

mnemonic for instruction with symbolic references resolved

getExceptions

public Class<?>[] getExceptions()

accept

public void accept(Visitor v)

Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object

getClassName

public String getClassName(ConstantPoolGen cpg)

Override the parent method because our classname is held elsewhere.

Overrides:

getClassName in class InvokeInstruction

Returns:

name of the referenced class/interface

getReferenceType

public ReferenceType getReferenceType(ConstantPoolGen cpg)

Since InvokeDynamic doesn't refer to a reference type, just return java.lang.Object, as that is the only type we can say for sure the reference will be.

Overrides:

getReferenceType in class FieldOrMethod

Parameters:

cpg - the ConstantPoolGen used to create the instruction

Returns:

an ObjectType for java.lang.Object

Since:

6.1
