Uses of Expression in org.yamcs.yarch.streamsql

Subclasses of Expression in org.yamcs.yarch.streamsql

Modifier and Type	Class	Description
class	AdditiveExpression
class	AggregateExpression	Expressions containing aggregates are computed in two phases: phase 1: the input tuples are passed to a list of expressions composed by the group by columns and the list of aggregates phase 2: the output tuples of phase 1 are passed to the list of original select list.
class	AggregateListExpression
class	AndExpression
class	ArgumentExpression	This corresponds to an ?
class	ArrayExpression
class	BitwiseExpression
class	ColumnExpression	Represents a column in a query, for example x and y below: select x from table where y > 0
class	CompilableAggregateExpression
class	ExponentExpression
class	FirstValExpression
class	InExpression
class	IsNullExpression
class	LikeExpression
class	MultiplicativeExpression
class	NegativeExpression
class	NotExpression
class	NullExpression	This represents a NULL value coming from some sql expression for example: select null from x
class	OrExpression
class	RelationalExpression	Expressions of type x > y or x=y
class	ValueExpression	This represents a constant value coming from some sql expression for example: select 3 from x
