Classes in org.openrefine.grel.ast that implement GrelExpr

Modifier and Type	Class	Description
class	ArrayExpr
class	ControlCallExpr	An abstract syntax tree node encapsulating a control call, such as "if".
class	FieldAccessorExpr	An abstract syntax tree node encapsulating a field accessor, e.g., "cell.value" is accessing the field named "value" on the variable called "cell".

class	LiteralExpr	An abstract syntax tree node encapsulating a literal value.
class	OperatorCallExpr	An abstract syntax tree node encapsulating an operator call, such as "+".
class	PureArgumentsExpr	An abstract class for an expression whose column dependencies are the union of those of their arguments.
class	VariableExpr	An abstract syntax tree node encapsulating the retrieval of a variable's content.
