net.esper.eql.expression.ExprEvaluator

Packages that use ExprEvaluator
net.esper.eql.core Contains EQL statement specification classes define the constructs that make up an EQL statement, such as the list of items in the select clause, the insert-into stream name and property names etc. 
net.esper.eql.expression This package contains the EQL expression nodes that represent all expressions such as used in select clauses, group-by and having clauses, or order-by clauses 
net.esper.eql.view Internal processing views for output rate limiting, filtering and internal event routing
