OpenJDK 1.22 · com.sun.org.apache.bcel.internal.generic.InvokeInstruction

Access	Constructor and Description
pack-priv	InvokeInstruction() Empty constructor needed for Instruction.readInstruction.
protected	InvokeInstruction(final short opcode, final int to constant pool index)

Method Summary

Modifier and Type	Method and Description
public int	Returns: Number of words consumed from stack by this instruction consumeStack(final ConstantPoolGen cpg) Overrides com.sun.org.apache.bcel.internal.generic.Instruction.consumeStack. Implements com.sun.org.apache.bcel.internal.generic.StackConsumer.consumeStack. Also works for instructions whose stack effect depends on the constant pool entry they reference.
public Type[]	Returns: argument types of referenced method. getArgumentTypes(final ConstantPoolGen cpg)
public String	Returns: name of the referenced class/interface getClassName(final ConstantPoolGen cpg) Overrides com.sun.org.apache.bcel.internal.generic.FieldOrMethod.getClassName. Deprecated This overrides the deprecated version as we know here that the referenced class may legally be an array.
public String	Returns: name of referenced method. getMethodName(final ConstantPoolGen cpg)
public Type	Returns: return type of referenced method. getReturnType(final ConstantPoolGen cpg)
public Type	Returns: return type of referenced method. getType(final ConstantPoolGen A ConstantPoolGen cpg) Overrides com.sun.org.apache.bcel.internal.generic.CPInstruction.getType. Implements com.sun.org.apache.bcel.internal.generic.LoadClass.getType, com.sun.org.apache.bcel.internal.generic.TypedInstruction.getType. Returns the type associated with this instruction.
public int	Returns: Number of words produced onto stack by this instruction produceStack(final ConstantPoolGen cpg) Overrides com.sun.org.apache.bcel.internal.generic.Instruction.produceStack. Implements com.sun.org.apache.bcel.internal.generic.StackProducer.produceStack. Also works for instructions whose stack effect depends on the constant pool entry they reference.
public String	Returns: mnemonic for instruction with symbolic references resolved toString(final ConstantPool cp) Overrides com.sun.org.apache.bcel.internal.generic.CPInstruction.toString.

getType	back to summary
public Type getType(final ConstantPoolGen cpg) Overrides com.sun.org.apache.bcel.internal.generic.CPInstruction.getType. Implements com.sun.org.apache.bcel.internal.generic.LoadClass.getType, com.sun.org.apache.bcel.internal.generic.TypedInstruction.getType. Doc from com.sun.org.apache.bcel.internal.generic.LoadClass.getType. Returns the type associated with this instruction. LoadClass instances are always typed, but this type does not always refer to the type of the class or interface that it possibly forces to load. For example, `GETFIELD` would return the type of the field and not the type of the class where the field is defined. If no class is forced to be loaded, `null` is returned. An example for this is an `NEWARRAY` instruction that creates an `int[][]`. Parameters cpg:ConstantPoolGen A ConstantPoolGen Returns:Type return type of referenced method. Annotations @Override
