Constructs a new int parameter. |
Method Summary | |
protected void |
acceptIOPerformer(IOPerformer performer,
DataBuffer source,

clone()
|
boolean |
equals(java.lang.Object obj)
Compares this Parameter object to a given object. |
protected DataBuffer |
getDataBuffer()
Returns current data storage. |
protected int |
getDataBufferOffset()
Returns current offset within data storage. |
int |
getLength()
Returns a length of the parameter in memory. |
long |
getValue()
Returns integer value converted to long |
void |
pop(DataBuffer stackBuffer,
int offset,
boolean invokedByCallback)
Default implementation, which does nothing as most primitive types do nothing on pop. |
void |
push(DataBuffer stackBuffer,
int offset,
boolean invokedByCallback)
Writes a parameter to a function stacks |
void |
read(DataBuffer stackBuffer,
int offset,
boolean invokedByCallback)
Reads this parameter from a specified data source. |
protected void |
setDataBuffer(DataBuffer newSource,
int newOffset)
Sets the data buffer this parameter should use to store data and an offset in bytes within that buffer. |
void |
setValue(long val)
Sets integer value |

toLong()
|
java.lang.String |
toString()
|
void |
write(DataBuffer stackBuffer,
int offset,
boolean invokedByCallback)
Writes this parameter to a specified data source. |

protected void acceptIOPerformer(IOPerformer performer, DataBuffer source, int initialOffset, boolean isReadOperation, boolean invokedByCallback)
Parameter
performer
is responsible for I/Oing the
parameter. Users implementing a complex parameter from scratch (i.e. not by extending a pre-existing class
such as Structure
or Pointer
) may wish to override this method to make a performer
visit object internal parts.
