Method Detail

accept

public void accept(ExpressionVisitor builder)
            throws Exception

Description copied from interface: SQLExpression

Most uses of this class have been implemented with a visitor pattern. Create your own ExpressionVisitor and call this method with it.

accept in interface SQLExpression

Throws:

addClasses

public void addClasses(Collection<Class<? extends PersistentRecord>> classSet)

Description copied from interface: SQLExpression

Adds all persistent classes that are brought into the SQL context by this clause: FROM clauses, JOINs, UPDATEs, anything that could create a new table abbreviation. This method should recurse into any subordinate state that may in turn bring in new classes so that sub-queries work correctly.

Specified by:

addClasses in interface SQLExpression

operator

public abstract String operator()

Returns the string representation of the operator.

getLeftHandSide

public SQLExpression getLeftHandSide()

getRightHandSide

public SQLExpression getRightHandSide()
