Method Detail

write

public void write(DataBuffer stackBuffer,
                  int offset,
                  boolean invokedByCallback)
           throws MemoryAccessViolationException

Description copied from class: Parameter

Writes this parameter to a specified data source.

Overrides:

write in class DelegatingParameter

Throws:

MemoryAccessViolationException

read

public void read(DataBuffer stackBuffer,
                 int offset,
                 boolean invokedByCallback)
          throws MemoryAccessViolationException

Description copied from class: Parameter

Reads this parameter from a specified data source.

Overrides:

read in class DelegatingParameter

Throws:

MemoryAccessViolationException

push

public void push(DataBuffer stackBuffer,
                 int offset,
                 boolean invokedByCallback)
          throws MemoryAccessViolationException

Description copied from class: Parameter

Writes a parameter to a function stacks.

Overrides:

push in class DelegatingParameter

Throws:

MemoryAccessViolationException

pop

public void pop(DataBuffer stackBuffer,
                int offset,
                boolean invokedByCallback)
         throws MemoryAccessViolationException

Description copied from class: Parameter

Default implementation that does nothing because most primitive types do nothing on pop. Reads a parameter from a function stack.

Overrides:

pop in class DelegatingParameter

Throws:

MemoryAccessViolationException

acceptIOPerformer

protected void acceptIOPerformer(IOPerformer performer,
                                 DataBuffer source,
                                 int initialOffset,
                                 boolean isReadOperation,
                                 boolean invokedByCallback)

Description copied from class: Parameter

Implementation of a Visitor pattern for parameter IO. A performer is responsible for reading and writing 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 DelegatingParameter

Parameters:

performer - a 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.

clone

public java.lang.Object clone()

Specified by:

clone in class Parameter

getDebugInfo

public java.lang.String getDebugInfo()

Description copied from class: Parameter

Return debug info for JNIWrapper parameter.

Overrides:

getDebugInfo in class DelegatingParameter

Returns:

debug info
