store object reference in array : index : visitInsn()
- Description
- This stores an object reference it in an array of objects.
arrayref is a reference to an array of object references. index
is an int. value is the object reference to be stored in the array.
arrayref, index and value are removed from the stack, and
value is stored in the array at the given index.
The runtime type of value must be assignment-compatible with the type of
the array. For example, if the array is declared as an array of Threads, then
value must either be null or an instance of Thread or one of
its subclasses. An ArrayStoreException is generated if you attempt to store an
incompatible type of object in an array. Assignment compatibility is described
in more detail in Chapter 7. - Exceptions
- ArrayIndexOutOfBoundsException - index is < 0 or >=
arrayref.length
ArrayStoreException - value is not compatible with the type of the
array
NullPointerException - arrayref is null - Notes
- Array indices start at 0 (the first entry in the array is at
index 0).
