Member Function Documentation

processValue()

template<typename INT>

void clues::item::IntValueT< INT >::processValue ( const Tracee & )

inlineoverrideprotectedvirtual

Processes the value stored in m_val acc. to the actual item type.

This function is called for all parameter types upon entry to a system call, and for ItemType::RETVAL upon exit from a system call.

For parameters of ItemType::PARAM_OUT this callback can be used to reset any stored data to be filled in later when updateData() is called.

Reimplemented from clues::SystemCallItem.

str()

template<typename INT>

Returns a human readable string representation of the item.

This member function should be specialized in derived classes to output the item's data in a fashion suitable for the concrete item type.
