public class Const
extends com.jniwrapper.DelegatingParameter

Represents a read-only parameter. It's a wrapper for real Parameter object.


Constructor Summary
Const(Const t)
          Constructs a copy of Const instance
Const(Parameter param)
          Constructs Const object taking wrapping Parameter object
 
Method Summary
protected  void acceptIOPerformer(IOPerformer performer, DataBuffer source, int initialOffset)
          Realization of a Visitor pattern for parameter IO.

public Const(Parameter param)
Constructs Const object taking wrapping Parameter object

public Const(Const t)
Constructs a copy of Const instance

Method Detail

read

public void read(DataBuffer stackBuffer,
                 int offset)
          throws MemoryAccessViolationException
Description copied from class: Parameter
Reads this parameter from a specified data source.

Overrides:
read in class com.jniwrapper.DelegatingParameter
MemoryAccessViolationException

clone

public java.lang.Object clone()
Specified by:
clone in class Parameter

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object

acceptIOPerformer

protected void acceptIOPerformer(IOPerformer performer,
                                 DataBuffer source,
                                 int initialOffset)
Description copied from class: Parameter
Realization of a Visitor pattern for parameter IO. A 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.

Overrides:
acceptIOPerformer in class Parameter
Parameters:
performer - visitor responsible for I/Oing the parameter
source - data buffer for I/O operation
initialOffset - I/O operation offset of this parameter in the buffer

setBuffer

protected void setBuffer(DataBuffer newSource,
                         int newOffset)
Description copied from class: Parameter
Sets the data buffer this parameter should use to store data and an offset in bytes within that buffer.

Overrides:
setBuffer in class Parameter

getBuffer

protected DataBuffer getBuffer()
Description copied from class: Parameter
Returns current data storage.

Overrides:
getBuffer in class Parameter

getOffset

protected int getOffset()
Description copied from class: Parameter
Returns current offset within data storage.

Overrides:
getOffset in class Parameter

getLength

public int getLength()
Description copied from class: Parameter
Returns a length of the parameter in memory. This method is analogous to C sizeof() operator.

Specified by:
getLength in class Parameter

write

public void write(DataBuffer stackBuffer,
                  int offset)
           throws MemoryAccessViolationException
Description copied from class: Parameter
Writes this parameter to a specified data source.

Specified by:
write in class Parameter
MemoryAccessViolationException
