BType
A BType is either a primitve type, a ClassBType, an ArrayBType of one of these, or a MethodType referring to BTypes.
Value members
Concrete methods
- Returns
The Java descriptor of this type. Examples:
- int: I
- java.lang.String: Ljava/lang/String;
- int[]: [I
- Object m(String s, double d): (Ljava/lang/String;D)Ljava/lang/Object;
Compute the upper bound of two types. Takes promotions of numeric primitives into account.

The asm.Type corresponding to this BType.
The asm.Type corresponding to this BType.
Note about asm.Type.getObjectType (*): For class types, the method expects the internal name, i.e. without the surrounding 'L' and ';'. For array types on the other hand, the method expects a full descriptor, for example "[Ljava/lang/String;".
See method asm.Type.getType that creates a asm.Type from a type descriptor
- for an OBJECT type, the 'L' and ';' are not part of the range of the created Type
- for an ARRAY type, the full descriptor is part of the range
Some JVM opcodes have typed variants. This method returns the correct opcode according to the type.

- Value Params
- opcode
A JVM instruction opcode. This opcode must be one of ILOAD, ISTORE, IALOAD, IASTORE, IADD, ISUB, IMUL, IDIV, IREM, INEG, ISHL, ISHR, IUSHR, IAND, IOR IXOR and IRETURN.
- Returns
The opcode adapted to this java type. For example, if this type is
floatandopcodeisIRETURN, this method returnsFRETURN.
