public class CQ
extends java.lang.Object

Context qualifiers. This class may not be instantiated.

Field Summary

static int	BUFFERSYMBOL Referencing a buffer symbol.
static int	INIT Is the symbol reference also an initializer? i.e.
static int	INITWEAK INIT, but for a "weak" scoped buffer
static int	REF Referencing the symbol's value.
static int	REFUP Reference and update the symbol's value.
static int	SCHEMATABLESYMBOL A schema table symbol.
static int	SYMBOL We are strictly referencing the symbol - not its value.
static int	TEMPTABLESYMBOL A temp or work table symbol.
static int	UPDATING Updating the symbol's value.

Method Summary

static boolean	isRead(int cq) Is symbol's value "read" in this context?
static boolean	isWrite(int cq) Is the symbol's value "written" in this context?
