Methods in net.sf.jec that return Operator

Operator	ExpressionEval.getCachedOperator(java.lang.Object ctx, java.lang.String expr) This method completely encapsulates the internal data representation.
Operator	ExpressionCompiler.compileOperator(java.lang.String expr) Compiles an expression into an operator

Methods in net.sf.jec with parameters of type Operator

void	Operator.setArgumentOperators(Operator[] argOps)

Constructors in net.sf.jec with parameters of type Operator

Operator(Operator nestedOp)
Creates a new operator that nest another operator

InvertibleOperator(Operator nestedOp)
Creates a new operator that nest another operator

IndexerOperator(Operator indexOperator, Operator nestedOp, boolean throwExceptions)
This operator requires object conversion and an operator chain that resolves the selected index.

BooleanOperator(java.lang.String type, Operator op1, Operator op2, boolean throwExceptions)
Creates a new instance of BooleanOperator

AssignOperator(InvertibleOperator op1, Operator op2, boolean throwExceptions)
Creates a new instance of AssignOperator

ArithmeticOperator(java.lang.String type, Operator op1, Operator op2, boolean throwExceptions)
Creates a new instance of BooleanOperator

AccessorOperator(java.lang.String field, Operator nestedOp, boolean throwExceptions)
Creates a new AccessorOperator that will try to get and set the field property of the context

Uses of Operator in net.sf.jec.namedop

Subclasses of Operator in net.sf.jec.namedop

class	AvgOperator AvgOperator acts over a collection of elements, applying its argument operator to each element, and averaging the results into a total average.
class	CountOperator CountOperator counts the amount of elements in the context collection.
class	GroupByOperator GroupByOperator returns a Map containing keyed groups of elements.
class	GroupOperator GroupOperator is the abstract parent class of every operator that operates over a group (an object implementing the Map interface)
class	IfOperator IfOperator evaluates a first boolean argument, evaluating and returning the second or thirth arguments when true or false respectively.
class	MaxOperator MaxOperator acts over a collection of elements, applying its argument operator to each element, and returning the maximum result value.
class	MinOperator MinOperator acts over a collection of elements, applying its argument operator to each element, and returning the minimum result value.
class	OrderByOperator OrderByOperator sorts a Collection of elements by applying the argument operator to each element and comparing between the resulting values.
class	SelectOperator SelectOperator operates over a Collection, selecting those elements that evaluate into 'true' when the boolean operator argument is applied.
class	SumOperator SumOperator acts over a collection of elements, applying its argument operator to each element, and adding the results into a total sum.
class	TableOperator TableOperator operates over an object collection and returns a table, result of applying operators for each column.

Constructors in net.sf.jec.namedop with parameters of type Operator

ContextComparator(java.lang.Object rootCtx, Operator operator)
Creates a new ContextComparator given the Operator and context Object needed to complete the expression whose result will be compared.
