Field Detail
-
T_TOP
static final byte T_TOP
Special type code for the "Top" type in the lattice.- See Also:
- Constant Field Values
-
T_LONG_EXTRA
static final byte T_LONG_EXTRA
Special type that represents the value store in local n+1 when a long value is stored in local n.- See Also:
- Constant Field Values
-
T_DOUBLE_EXTRA
static final byte T_DOUBLE_EXTRA
Special type that represents the value store in local n+1 when a double value is stored in local n.- See Also:
- Constant Field Values
-
T_BOTTOM
static final byte T_BOTTOM
Special type code for the "Bottom" type in the lattice.- See Also:
- Constant Field Values
-
T_NULL
static final byte T_NULL
Special type code for the "Null" type. This is a type which is higher in the lattice than any object type, but lower than the overall Top type. It represents the type of the null value, which may logically be merged with any object type without loss of information.- See Also:
- Constant Field Values
-
T_EXCEPTION
static final byte T_EXCEPTION
Special type code for "Exception" object type, which is an instance of the ExceptionObjectType class. These instances maintain an ExceptionSet to keep track of possible exceptions that are feasible, and whether those exceptions are explicit or implicit.- See Also:
- Constant Field Values
-
T_AVAIL_TYPE
static final byte T_AVAIL_TYPE
A Type code that is available for "user-defined" types. Any type code equal or greated than this one is guaranteed to be distinct from both standard and extended types.- See Also:
- Constant Field Values
