const-class

+ +

Purpose

+ +

+Move a reference to the class specified by the given index into the specified +register. In the case where the indicated type is primitive, this will store a +reference to the primitive type's degenerate class. +

+ +

Details

+ + + + + + + + + + + + + + + + +

Op & Format	Mnemonic / Syntax	Arguments
1c 21c	const-class vAA, type@BBBB	`A:` destination register (8 bits) + `B:` type index

+ +

Constraints

+ +

+ A must be a valid register index in the current stack frame. +
+ B must be a valid index into the type constant pool. +

+ +

Behavior

+ +

+ An attempt is made to get a reference to the class C the name of which is + contained in type pool entry B. +
+ If B refers to a primitive type, the corresponding degenerate class is used + instead. +
+ If C has not been loaded and resolved before, it is being loaded and + resolved. All exceptions that are possible during class loading can occur at + this point. +
+ A reference to C is moved into register vA, that is, vA' = C. +
+ If v(A-1) is the lower half of a register pair, v(A-1)' becomes undefined. +
+ If v(A+1) is the upper half of a register pair, v(A+1)' becomes undefined. +

+ +

Exceptions

+ +

+ ClassNotFoundException is thrown if the class does not exist at all. +
+ VerifyError is thrown if the class does exist, but could not be verified. +
