Class Summary

Class	Description
BinaryExpressionNode	A Node representing an binary expression
ExplainNode	This class wraps the PostgreSQL EXPLAIN node and optional parameters that can be used as a prefix for a query to retrieve explanations of an OQL query without the need to directly inspect the generated SQL query.
FromNode	A Node representing the from part of a query
InterpretedOQLQuery	Interpretes a given OQL query and provides easily useable information about it and helper objects to check and handle BOs accordingly.
LimitNode	A Node representing the limit part of a query
ListNode	A Node representing a list expression
LiteralNode	A Node representing an unary expression
OQLQuery	The main entry point for the OQL translator.
OrderNode	A Node representing the order part of a query
ParameterNode	A Node representing an unary expression
Parser	Generates a parse tree for a stream of tokens representing an OQL query.
ParseTreeNode	A Node in the Parse tree which is generated by the Parser as the tree representation of the OQL Query.
PathNode	A Node in the Parse tree which represents a path expression There's some parsing going on here as well, just because the path expression has some special syntax for special needs which I don't want to pollute into the 'pure' oql expression parsing.
PathPart	A PathPart object represents a single path part (between the dots), including the left dot, telling, wether it's a null safe one (?.)
QueryExpressionNode	A Node representing a Query expression
QueryNameSpace	This class collects all the roots, joins and their respective aliases of an query to properly render them to an SQL statement when needed.
SelectNode	A Node representing the select part of a query
SemiFullTextQuery	A class which helps building queries out of string expressions typed into the MyTISM bookmarks.
SimpleOQLQueryHolder
SQLQuery	Holds the SQL generated by the OQLQuery.
TextQueryLexer	A class to separate a users input into 'terms', each of them may ask to supply a search term (aka 'may') supply a mandatory term (aka 'must') supply a forbidden term (aka 'mustnt') raw query fragment
TextQueryTerm
Token	The Lexer produces these from the OQL Query String.
UnaryExpressionNode	A Node representing an unary expression.
WhereNode	A Node representing the where part of a query.
