Member Function Documentation

◆ processValue()

void clues::item::UserID::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.
