Uses of Expr in condor.classad

Subclasses of Expr in condor.classad

class	AttrRef A reference to another attribute.
class	CondExpr A conditional expression.
class	Constant A constant (Integer, Real, etc.).
class	FuncCall A function call.
class	ListExpr A list of expressions.
class	Op A unary or binary expression.
class	RecordExpr A "record" expression (also known as a "classad").
class	SelectExpr An internal (non-leaf) node of an expression tree, representing a selection of component of a record.
class	SubscriptExpr A selection from a list.

Fields in condor.classad declared as Expr

Expr[]	FuncCall.args The parameters to the function.
Expr	SubscriptExpr.base The left argument (base expression) of the subscript operator.
Expr	SubscriptExpr.selector The right argument (subscript) of the selection operator.
Expr	SelectExpr.base The left argument (base expression) of the selection operator.
Expr[]	Query.selectClause The expressions in the SelectionClause.
Expr	Query.whereClause The "where" clause or null if the "where" clause was omitted.
Expr	Op.arg1 The first (or only) operand.
Expr	Op.arg2 The second operand; null if the operator is unary.
Expr	CondExpr.ec The condition (first component of the expression)
Expr	CondExpr.et The true part (second component of the expression)
Expr	CondExpr.ef The false part (third component of the expression)
