public class CTMemory

extends ScopedMemory

CTMemory represents a constant-sized memory scope. It uses stack allocation and is very fast and has predictable performance.

Field Summary

private long

minimum This constructs a CTMemory of the appropriate size (the maximum allowed to be allocated in the scope).

Constructor Summary

CTMemory(long size)

CTMemory(long minimum, long maximum)

Method Summary

void	done() Invoke this method when you're finished with the MemoryArea (could be a finalizer if we had finalizers...)
private void	doneNative() This will actually free the memory (if refcount = 0).
protected void	initNative(long sizeInBytes) Initialize the native component of this MemoryArea (set up the MemBlock)
private void	initNative(long minimum, long maximum)
java.lang.String	toString() Returns a representation of this CTMemory object

Field Detail

minimum

private long minimum

This constructs a CTMemory of the appropriate size (the maximum allowed to be allocated in the scope). The performance hit of allocating a large block of memory is taken when this constructor is called, or reused after refCount drops to zero.

toString

public java.lang.String toString()

Returns a representation of this CTMemory object

Overrides:

toString in class ScopedMemory

Returns:

The string representation.

initNative

protected void initNative(long sizeInBytes)

Initialize the native component of this MemoryArea (set up the MemBlock)

done

public void done()

Invoke this method when you're finished with the MemoryArea (could be a finalizer if we had finalizers...)

doneNative

private void doneNative()

This will actually free the memory (if refcount = 0).
