Method Detail

create
```
public static MemoryStack create()
```
Creates a new MemoryStack with the default size.

create
```
public static MemoryStack create(int size)
```
Creates a new MemoryStack with the specified size.

Parameters:

size - the maximum number of bytes that may be allocated on the stack

push
```
public MemoryStack push()
```
Stores the current stack pointer and pushes a new frame to the stack.
This method should be called when entering a method, before doing any stack allocations. When exiting a method, call the MemoryStack.pop() method to restore the previous stack frame.

Pairs of push/pop calls may be nested. Care must be taken to:
- match every push with a pop
- not call pop before push has been called at least once
- not nest push calls to more than the maximum supported depth
Returns:

this stack

pop
```
public MemoryStack pop()
```
Pops the current stack frame and moves the stack pointer to the end of the previous stack frame.

Returns:

this stack

close
```
public void close()
```
Calls MemoryStack.pop() on this MemoryStack.
This method should not be used directly. It is called automatically when the MemoryStack is used as a resource in a try-with-resources statement.

Specified by:

close in interface java.lang.AutoCloseable

getAddress
```
public long getAddress()
```
Returns the address of the backing off-heap memory.
The stack grows "downwards", so the bottom of the stack is at address + size, while the top is at address.

getSize
```
public int getSize()
```
Returns the size of the backing off-heap memory.
This is the maximum number of bytes that may be allocated on the stack.

getFrameIndex
```
public int getFrameIndex()
```
Returns the current frame index.
This is the current number of nested MemoryStack.push() calls.

getPointer
```
public int getPointer()
```
Returns the current stack pointer.
The stack grows "downwards", so when the stack is empty pointer is equal to size. On every allocation pointer is reduced by the allocated size (after alignment) and address + pointers points to the last byte of the last allocation.

Effectively, this methods returns how many more bytes may be allocated on the stack.

setPointer
```
public void setPointer(int pointer)
```
Sets the current stack pointer.
This method directly manipulates the stack pointer. Using it irresponsibly may break the internal state of the stack. It should only be used in rare cases or in auto-generated code.

nmalloc
```
public long nmalloc(int size)
```
Calls MemoryStack.nmalloc(int, int) with alignment equal to 1.

Parameters:

size - the allocation size

Returns:

the memory address on the stack for the requested allocation

nmalloc
```
public long nmalloc(int alignment,
                    int size)
```
Allocates a block of size bytes of memory on the stack. The content of the newly allocated block of memory is not initialized, remaining with indeterminate values.

Parameters:

alignment - the required alignment

size - the allocation size

Returns:

the memory address on the stack for the requested allocation

ncalloc
```
public long ncalloc(int alignment,
                    int num,
                    int size)
```
Allocates a block of memory on the stack for an array of num elements, each of them size bytes long, and initializes all its bits to zero.

Parameters:

alignment - the required element alignment

num - num the number of elements to allocate

size - the size of each element

Returns:

the memory address on the stack for the requested allocation

malloc
```
public java.nio.ByteBuffer malloc(int alignment,
                                  int size)
```
Allocates an aligned ByteBuffer on the stack.

Parameters:

alignment - the required buffer alignment

size - the number of elements in the buffer

Returns:

the allocated buffer
