Parameters: desc the class descriptor of the annotation class. visible true if the annotation is visible at runtime.
Returns: a non null visitor to visit the annotation values.
Returns: a non null visitor to the visit the actual default value of this annotation interface method. The 'name' parameters passed to the methods of this annotation visitor are ignored. Moreover, exacly one visit method must be called on this annotation visitor, followed by visitEnd.
Parameters: attr an attribute.
Parameters: opcode the opcode of the type instruction to be visited. This opcode is either GETSTATIC, PUTSTATIC, GETFIELD or PUTFIELD. owner the internal name of the field's owner class (see {@link Type#getInternalName() getInternalName}). name the field's name. desc the field's descriptor (see {@link Type Type}).
Parameters: var index of the local variable to be incremented. increment amount to increment the local variable by.
Parameters: opcode the opcode of the instruction to be visited. This opcode is either NOP, ACONST_NULL, ICONST_M1, ICONST_0, ICONST_1, ICONST_2, ICONST_3, ICONST_4, ICONST_5, LCONST_0, LCONST_1, FCONST_0, FCONST_1, FCONST_2, DCONST_0, DCONST_1, IALOAD, LALOAD, FALOAD, DALOAD, AALOAD, BALOAD, CALOAD, SALOAD, IASTORE, LASTORE, FASTORE, DASTORE, AASTORE, BASTORE, CASTORE, SASTORE, POP, POP2, DUP, DUP_X1, DUP_X2, DUP2, DUP2_X1, DUP2_X2, SWAP, IADD, LADD, FADD, DADD, ISUB, LSUB, FSUB, DSUB, IMUL, LMUL, FMUL, DMUL, IDIV, LDIV, FDIV, DDIV, IREM, LREM, FREM, DREM, INEG, LNEG, FNEG, DNEG, ISHL, LSHL, ISHR, LSHR, IUSHR, LUSHR, IAND, LAND, IOR, LOR, IXOR, LXOR, I2L, I2F, I2D, L2I, L2F, L2D, F2I, F2L, F2D, D2I, D2L, D2F, I2B, I2C, I2S, LCMP, FCMPL, FCMPG, DCMPL, DCMPG, IRETURN, LRETURN, FRETURN, DRETURN, ARETURN, RETURN, ARRAYLENGTH, ATHROW, MONITORENTER, or MONITOREXIT.
Parameters: opcode the opcode of the instruction to be visited. This opcode is
either BIPUSH, SIPUSH or NEWARRAY. operand 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
{@link Opcodes#T_BOOLEAN}, {@link Opcodes#T_CHAR},
{@link Opcodes#T_FLOAT}, {@link Opcodes#T_DOUBLE},
{@link Opcodes#T_BYTE}, {@link Opcodes#T_SHORT},
{@link Opcodes#T_INT} or {@link Opcodes#T_LONG}.
Parameters: opcode 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 the operand of the instruction to be visited. This operand is a label that designates the instruction to which the jump instruction may jump.
Parameters: label a {@link Label Label} object.
Parameters: cst the constant to be loaded on the stack. This parameter must be a non null {@link Integer}, a {@link Float}, a {@link Long}, a {@link Double} a {@link String} (or a {@link Type} for .class constants, for classes whose version is 49.0 or more).
Parameters: line a line number. This number refers to the source file from which the class was compiled. start the first instruction corresponding to this line number.
Throws: IllegalArgumentException if start has not already been visited by this visitor (by the {@link #visitLabel visitLabel} method).
Parameters: name the name of a local variable. desc the type descriptor of this local variable. signature the type signature of this local variable. May be null if the local variable type does not use generic types. start the first instruction corresponding to the scope of this local variable (inclusive). end the last instruction corresponding to the scope of this local variable (exclusive). index the local variable's index.
Throws: IllegalArgumentException if one of the labels has not already been visited by this visitor (by the {@link #visitLabel visitLabel} method).
Parameters: dflt beginning of the default handler block. keys the values of the keys. labels beginnings of the handler blocks. labels[i] is the beginning of the handler block for the keys[i] key.
Parameters: maxStack maximum stack size of the method. maxLocals maximum number of local variables for the method.
Parameters: opcode the opcode of the type instruction to be visited. This opcode is either INVOKEVIRTUAL, INVOKESPECIAL, INVOKESTATIC or INVOKEINTERFACE. owner the internal name of the method's owner class (see {@link Type#getInternalName() getInternalName}). name the method's name. desc the method's descriptor (see {@link Type Type}).
Parameters: desc an array type descriptor (see {@link Type Type}). dims number of dimensions of the array to allocate.
Parameters: parameter the parameter index. desc the class descriptor of the annotation class. visible true if the annotation is visible at runtime.
Returns: a non null visitor to visit the annotation values.
Parameters: min the minimum key value. max the maximum key value. dflt beginning of the default handler block. labels beginnings of the handler blocks. labels[i] is the beginning of the handler block for the min + i key.
Parameters: start beginning of the exception handler's scope (inclusive). end end of the exception handler's scope (exclusive). handler beginning of the exception handler's code. type internal name of the type of exceptions handled by the handler, or null to catch any exceptions (for "finally" blocks).
Parameters: opcode the opcode of the type instruction to be visited. This opcode is either NEW, ANEWARRAY, CHECKCAST or INSTANCEOF. desc the operand of the instruction to be visited. This operand is must be a fully qualified class name in internal form, or the type descriptor of an array type (see {@link Type Type}).
Parameters: opcode the opcode of the local variable instruction to be visited. This opcode is either ILOAD, LLOAD, FLOAD, DLOAD, ALOAD, ISTORE, LSTORE, FSTORE, DSTORE, ASTORE or RET. var the operand of the instruction to be visited. This operand is the index of a local variable.
