 java.nio.Buffer
java.nio.ByteBuffer
java.nio.BaseByteBuffer
java.nio.DirectByteBuffer
All known Subclasses: java.nio.ReadWriteDirectByteBuffer, java.nio.ReadOnlyDirectByteBuffer,
| DirectByteBuffer | | abstract class DirectByteBuffer extends BaseByteBuffer implements DirectBuffer(Code) | | DirectByteBuffer, ReadWriteDirectByteBuffer and ReadOnlyDirectByteBuffer
compose the implementation of platform memory based byte buffers.
DirectByteBuffer implements all the shared readonly methods and is extended
by the other two classes.
All methods are marked final for runtime performance.

| offset | | final protected int offset(Code) | | |
| safeAddress | | final protected SafeAddress safeAddress(Code) | | |

| DirectByteBuffer | | DirectByteBuffer(SafeAddress address, int capacity, int offset)(Code) | | |
| addressValidityCheck | | final public void addressValidityCheck()(Code) | | |
| free | | final public void free()(Code) | | Explicitly free the memory used by this direct byte buffer. If the memory
has already been freed then this is a no-op. Once the memory has been
freed then operations requiring access to the memory will throw an
IllegalStateException.
Note this is is possible that the memory is freed by code that reaches
into the address and explicitly frees it 'beneith' us -- this is bad
form.

| get | | final public byte get()(Code) | | |
| get | | final public byte get(int index)(Code) | | |
| getBaseAddress | | final public PlatformAddress getBaseAddress()(Code) | | |
| getByteCapacity | | final public int getByteCapacity()(Code) | | |
| getDouble | | final public double getDouble()(Code) | | |
| getDouble | | final public double getDouble(int index)(Code) | | |
| getEffectiveAddress | | final public PlatformAddress getEffectiveAddress()(Code) | | Answers the platform address of the start of this buffer instance.
You must not attempt to free the returned address!! It may not
be an address that was explicitly malloc'ed (i.e. if this buffer is the
result of a split); and it may be memory shared by multiple buffers.
If you can guarantee that you want to free the underlying memory call the
#free() method on this instance -- generally applications will rely on
the garbage collector to autofree this memory.
the effective address of the start of the buffer.
throws:
IllegalStateException - if this buffer address is known to have been freedpreviously. |
