author: Steve Ebersole

Fields Summary
Constructors Summary
Methods Summary
public FromClause getFromClause()
Retreives the from-clause in effect for this statement.
return
The from-clause for this statement; could be null if the from-clause has not yet been parsed/generated.
public antlr.collections.AST getWhereClause()
Retreives the where-clause defining the restriction(s) in effect for this statement.
Note that this will generate a where-clause if one was not found, so caution needs to taken prior to calling this that restrictions will actually exist in the resulting statement tree (otherwise "unexpected end of subtree" errors might occur during rendering).
return
The where clause.
public boolean hasWhereClause()
Does this statement tree currently contain a where clause?
return
True if a where-clause is found in the statement tree and that where clause actually defines restrictions; false otherwise.
