public interface INativeHandle
A "handle" to a piece of memory (in c space).
The handle combines an address and a memory chunk of a specified size.
| Method Summary | |
|---|---|
long |
getAddress()
The start address of the memory chunk |
byte |
getByte(int index)
Marshal the data at byte offset index from the start of the
memory chunk to a byte. |
byte[] |
getByteArray(int index,
int count)
Marshal the data at byte offset index from the start of the
memory chunk to a byte array of length count. |
long |
getCLong(int index)
Marshal the data at byte offset index from the start of the
memory chunk to a long. |
int |
getInt(int index)
Marshal the data at byte offset index from the start of the
memory chunk to an int. |
long |
getLong(int index)
Marshal the data at byte offset index from the start of the
memory chunk to a long value (which is always 8 byte). |
INativeHandle |
getNativeHandle(int index)
Marshal the data at byte offset index from the start of the
memory chunk to an INativeHandle. |
short |
getShort(int index)
Marshal the data at byte offset index from the start of the
memory chunk to a short. |
int |
getSize()
The size for the handle in bytes. |
String |
getString(int index)
Marshal the data at byte offset index from the start of the
memory chunk to a String. |
String |
getWideString(int index)
Marshal the data at byte offset index from the start of the
memory chunk to a String using the platform wide character conversion. |
INativeHandle |
offset(int offset)
Create a new INativeHandle, offset from this by
offset bytes. |
void |
setByte(int index,
byte value)
Write a byte to the memory at byte offset index from the
start of the memory chunk. |
void |
setByteArray(int index,
byte[] value,
int valueOffset,
int valueCount)
Write a byte array to the memory at byte offset index from
the start of the memory chunk. |

Write a long to the memory at byte offset index from the
start of the memory chunk. |
void |
setInt(int index,
int value)
Write an int to the memory at byte offset index from the
start of the memory chunk. |
void |
setLong(int index,
long value)
Write a long to the memory at byte offset index from the
start of the memory chunk. |
void |
setNativeHandle(int index,
INativeHandle valueHandle)
Write an INativeHandle to the memory at byte offset
index from the start of the memory chunk. |
void |
setShort(int index,
short value)
Write a short to the memory at byte offset index from the
start of the memory chunk. |
void |
setSize(int count)
Set the valid size for the handle to count bytes. |
void |
setString(int index,
String value)
Write a String to the memory at byte offset indexfrom the
start of the memory chunk. |
void |
setWideString(int index,
String value)
Write a String to the memory at byte offset indexfrom the
start of the memory chunk using the platform wide character conversion. |

memory chunk to a byte array of length count.
index - The byte offset from the start of the memory chunkcount - The size of the byte array
long getCLong(int index)
index from the start of the
memory chunk to a long. Get only the "platform" number of bytes.
index - The byte offset from the start of the memory chunk
int getInt(int index)
index from the start of the
memory chunk to an int.
index - The byte offset from the start of the memory chunk
long getLong(int index)
index from the start of the
memory chunk to a long value (which is always 8 byte).
index - The byte offset from the start of the memory chunk
INativeHandle getNativeHandle(int index)
index from the start of the
memory chunk to an INativeHandle.
index - The byte offset from the start of the memory chunk
INativeHandle marshaled from the memory chunkshort getShort(int index)
index from the start of the
memory chunk to a short.
index - The byte offset from the start of the memory chunk
int getSize()
You can not access bytes from outside the range defined by getAdddress + size.
String getString(int index)
index from the start of the
memory chunk to a String.
index - The byte offset from the start of the memory chunk
String getWideString(int index)
index from the start of the
memory chunk to a String using the platform wide character conversion.
index - The byte offset from the start of the memory chunk
INativeHandle offset(int offset)
INativeHandle, offset from this by
offset bytes.
offset - The byte offset from the start of the memory chunk
INativeHandle pointing to "getAddress() + offset".
void setByte(int index,
byte value)
index from the
start of the memory chunk.
index - The byte offset from the start of the memory chunkvalue - The value to write.
void setByteArray(int index,
