INVOKEINTERFACE
INVOKEINTERFACE()
- Empty constructor needed for the Class.newInstance() statement in
Instruction.readInstruction(). Not to be used otherwise.
INVOKEINTERFACE
public INVOKEINTERFACE(int index,
int nargs)
dump
public void dump(java.io.DataOutputStream out)
throws java.io.IOException
- Dump instruction as byte code to stream out.
- Overrides:
dump
in class CPInstruction
- Parameters:
out
- Output stream
- Throws:
java.io.IOException
getCount
public int getCount()
- The count argument according to the Java Language Specification,
Second Edition.
initFromFile
protected void initFromFile(ByteSequence bytes,
boolean wide)
throws java.io.IOException
- Read needed data (i.e., index) from file.
- Overrides:
initFromFile
in class CPInstruction
- Parameters:
bytes
- input streamwide
- wide prefix?
- Throws:
java.io.IOException
toString
public java.lang.String toString(ConstantPool cp)
- Overrides:
toString
in class InvokeInstruction
- Returns:
- mnemonic for instruction with symbolic references resolved
consumeStack
public int consumeStack(ConstantPoolGen cpg)
- Description copied from class:
InvokeInstruction
- Also works for instructions whose stack effect depends on the
constant pool entry they reference.
- Specified by:
consumeStack
in interface StackConsumer
- Overrides:
consumeStack
in class InvokeInstruction
- Returns:
- Number of words consumed from stack by this instruction
getExceptions
public java.lang.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
