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
- See Also:
- The invokedynamic instruction in The Java Virtual Machine Specification

Method Detail
-
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 classInstruction
- Parameters:
v
- Visitor object
-
dump
public void dump(java.io.DataOutputStream out) throws java.io.IOException
Dump instruction as byte code to stream out.- Overrides:
dump
in classCPInstruction
- Parameters:
out
- Output stream- Throws:
java.io.IOException
- Thrown when an I/O exception of some sort has occurred.
-
getClassName
public java.lang.String getClassName(ConstantPoolGen cpg)
Override the parent method because our class name is held elsewhere. Note: Contrary to this method's name it does not return the class name of the invoke target; rather it returns the name of the method that will be used to invoke the Lambda method generated by this invoke dynamic instruction.- Overrides:
getClassName
in classInvokeInstruction
- Returns:
- name of the referenced class/interface
-
getExceptions
public java.lang.Class<?>[] getExceptions()
-
getReferenceType
public ReferenceType getReferenceType(ConstantPoolGen cpg)
Since InvokeDynamic doesn't refer to a reference type, just returnObject
, as that is the only type we can say for sure the reference will be.- Overrides:
getReferenceType
in classFieldOrMethod
- Parameters:
cpg
- the ConstantPoolGen used to create the instruction- Returns:
- an ObjectType for
Object
- Since:
- 6.1
-
initFromFile
protected void initFromFile(ByteSequence bytes, boolean wide) throws java.io.IOException
Read needed data (i.e., index) from file.- Overrides:
initFromFile
in classCPInstruction
- Parameters:
bytes
- input streamwide
- wide prefix?- Throws:
java.io.IOException
- may be thrown if the implementation needs to read data from the file
