@Override

Overrides org.objectweb.asm.MethodVisitor.visitIntInsn.

Parameters

opcode:int

the opcode of the instruction to be visited. This opcode is either BIPUSH, SIPUSH or NEWARRAY.

operand:int

the operand of the instruction to be visited.
When opcode is BIPUSH, operand value should be between Byte.MIN_VALUE and Byte.MAX_VALUE.
When opcode is SIPUSH, operand value should be between Short.MIN_VALUE and Short.MAX_VALUE.
When opcode is NEWARRAY, operand value should be one of Opcodes#T_BOOLEAN, Opcodes#T_CHAR, Opcodes#T_FLOAT, Opcodes#T_DOUBLE, Opcodes#T_BYTE, Opcodes#T_SHORT, Opcodes#T_INT or Opcodes#T_LONG.

Annotations

@Override

Overrides org.objectweb.asm.MethodVisitor.visitInvokeDynamicInsn.

Doc from org.objectweb.asm.MethodVisitor.visitInvokeDynamicInsn.

Visits an invokedynamic instruction.

Parameters

name:String

the method's name.

descriptor:String

the method's descriptor (see Type).

bootstrapMethodHandle:Handle

the bootstrap method.

bootstrapMethodArguments:Object[]

the bootstrap method constant arguments. Each argument must be an Integer, Float, Long, Double, String, Type, Handle or ConstantDynamic value. This method is allowed to modify the content of the array so a caller should expect that this array may change.

Annotations

@Override

Overrides org.objectweb.asm.MethodVisitor.visitJumpInsn.

Doc from org.objectweb.asm.MethodVisitor.visitJumpInsn.

Visits a jump instruction. A jump instruction is an instruction that may jump to another instruction.

Parameters

opcode:int

the opcode of the type instruction to be visited. This opcode is either IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.

label:Label

the operand of the instruction to be visited. This operand is a label that designates the instruction to which the jump instruction may jump.

Annotations

@Override

Overrides org.objectweb.asm.MethodVisitor.visitLdcInsn.

Doc from org.objectweb.asm.MethodVisitor.visitLdcInsn.

Visits a LDC instruction. Note that new constant types may be added in future versions of the Java Virtual Machine. To easily detect new constant types, implementations of this method should check for unexpected constant types, like this:

if (cst instanceof Integer) {
    // ...
} else if (cst instanceof Float) {
    // ...
} else if (cst instanceof Long) {
    // ...
} else if (cst instanceof Double) {
    // ...
} else if (cst instanceof String) {
    // ...
} else if (cst instanceof Type) {
    int sort = ((Type) cst).getSort();
    if (sort == Type.OBJECT) {
        // ...
    } else if (sort == Type.ARRAY) {
        // ...
    } else if (sort == Type.METHOD) {
        // ...
    } else {
        // throw an exception
    }
} else if (cst instanceof Handle) {
    // ...
} else if (cst instanceof ConstantDynamic) {
    // ...
} else {
    // throw an exception
}

Parameters

value:Object

the constant to be loaded on the stack. This parameter must be a non null Integer, a Float, a Long, a Double, a String, a Type of OBJECT or ARRAY sort for .class constants, for classes whose version is 49, a Type of METHOD sort for MethodType, a Handle for MethodHandle constants, for classes whose version is 51 or a ConstantDynamic for a constant dynamic for classes whose version is 55.
