Class Summary

Class	Description
BooleanCaseWhenCollector	Collector that will collect all CASE WHEN expressions that look like boolean CASE WHEN statements, ie,
BooleanCollector	Simple collector that will return all operands that are used in Boolean expressions
CaseWhenCollector	Collector that will collect all expressions in a "case when" block.
Collector	A collect is a Node.Visitor that will collect items if they are accepted by the collector's accept() method.
Collector.Mode
ColumnNameTransformer	A Column Name transformer transforms a MBO Field Name into a Database Table Column, adding an optional Qualifier in the process, for Nodes that are Literal Nodes and if the Node's value is a field in the given ObjectName (MBO).
DivideByZeroValidator	Validates that the parsed node information does not contain explicit references to divide by 0 operations
ExprParser	An Expression Parser parses an expression, such as 'FIELDA+DateDiff(Now(), Later())+10' into a Parse Tree of Nodes that can be navigated and validated.
ExprParser.State
FieldPlaceholderParserHelper	Helps the parser by Turning nodes into a single Macro Node.
HasAttributeValidator	A Validator that will validate Listeral nodes in the parsed expression and test them to ensure they are actually valid mbo fields for the given mbo objectname.
JoiningParserHelper	Base class for a parser helper that will join a pattern of nodes, creating a new Node type.
MaximoMacroParserHelper	Helps the parser by Turning & NAME & nodes into a single &NAME& Macro Node.
MaximoMacroTransformer	ToStringVisitor Transformer for turning &MACRONAME& Nodes into macro values during a toString() transformation.
MultiParserHelper	Convenient way to allow multiple helpers to assist during the parsing phase.
MultiToStringTransformer	Convenient way to utilize multiple transformers when generating a toString()
Node	In a parsed expression, a "node" is simply piece of data in the parse tree.
Node.Type
Node.Visitor.State
Node.Visitor.Status
SafeDivideValidator	Divide By Attribute tests an expression and for cases when a field attribute is being used in the denominator of the expression.
ToStringVisitor	A ToString visitor is a Node visitor that will convert the parsed Node into a string representation.
TypeCollector	Type Collectors are used to collect nodes that match a given type.
ValueCollector	A Value Collector is used to collect nodes that match a given type an value.
WhitelistValidator	Simple WhiteList validator/collector.
