6.15 CAggregate
- Defined in namespace Smalltalk
- Category: Language-C interface
6.15.1 CAggregate class: accessing
- alignof
- Answer the receiver's instances required aligment
- sizeof
- Answer the receiver's instances size
6.15.2 CAggregate: accessing
- + anInteger
- Return another instance of the receiver's class which points at &receiver[anInteger] (or, if you prefer, what `receiver + anInteger' does in C).
- - intOrPtr
- If intOrPtr is an integer, return another instance of the receiver's class pointing at &receiver[-anInteger] (or, if you prefer, what `receiver - anInteger' does in C). If it is the same class as the receiver, return the difference in chars, i.e. in bytes, between the two pointed addresses (or, if you prefer, what `receiver - anotherCharPtr' does in C)
- addressAt: anIndex
- Access the array, returning a new Smalltalk CObject of the element type, corresponding to the given indexed element of the array. anIndex is zero-based, just like with all other C-style accessing.
- decr
- Adjust the pointer by sizeof(elementType) bytes down (i.e. --receiver)
- decrBy: anInteger
- Adjust the pointer by anInteger elements down (i.e. receiver -= anInteger)
- deref
- Access the object, returning a new Smalltalk object of the element type, corresponding to the dereferenced pointer or to the first element of the array.
- deref: aValue
- Modify the object, storing the object of the element type into the pointed address or in the first element of the array.
- derefAt: anIndex
- Access the array, returning a new Smalltalk object of the element type, corresponding to the given indexed element of the array. anIndex is zero-based, just like with all other C-style accessing.
- derefAt: anIndex put: aValue
- Store in the array the passed Smalltalk object `aValue', which should be of the element type, corresponding to the given indexed element. anIndex is zero-based, just like with all other C-style accessing.
- incr
- Adjust the pointer by sizeof(elementType) bytes up (i.e. ++receiver)
- incrBy: anInteger
- Adjust the pointer by anInteger elements up (i.e. receiver += anInteger)
- value
- Answer the address of the beginning of the data pointed to by the receiver.
- value: aValue
- Set the address of the beginning of the data pointed to by the receiver.
