public static final Collection<SearchOperator> CLAUSE_OPERATORS

Clause operators just join multiple expressions

Method Detail

parsePrefixUnaryOperatorValue

public static String parsePrefixUnaryOperatorValue(SearchOperator operator,
                                                   String expression)

parsePostfixUnaryOperatorValue

public static String parsePostfixUnaryOperatorValue(SearchOperator operator,
                                                    String expression)

parseBinaryOperatorValues

public static String[] parseBinaryOperatorValues(SearchOperator operator,
                                                 String expression)

splitOnClauses

public static String[] splitOnClauses(String expression)

Splits the expression by AND and OR operators. Does not trim empty clauses (these are probably syntax errors)

Parameters:

expression - the expression to parse

Returns:

string array of clauses, not including AND or OR operators

stripClauseOperators

public static String stripClauseOperators(String expression)

Strips AND and OR operators from the expression string

Parameters:

expression - the expression to parse

Returns:

string not including AND or OR operators

splitOnOperators

public static String[] splitOnOperators(String expression,
                                        Collection<SearchOperator> operators)

Splits the expression by the given operators. Does not trim empty parts.

Parameters:

expression - the expression to parse

Returns:

string array of clauses, not including specified operators

splitOnOperators

public static String[] splitOnOperators(String expression,
                                        SearchOperator... operators)

Splits the expression by the given operators. Does not trim empty parts.

Parameters:

expression - the expression to parse

Returns:

string array of clauses, not including specified operators

stripOperators

public static String stripOperators(String expression,
                                    Collection<SearchOperator> operators)

Strips AND and OR operators from the expression string

Parameters:

expression - the expression to parse

Returns:

string not including AND or OR operators

stripOperators

public static String stripOperators(String expression,
                                    SearchOperator... operators)

Strips AND and OR operators from the expression string

Parameters:

expression - the expression to parse

Returns:

string not including AND or OR operators

parseRange

public static Range parseRange(String rangeString)

parsePredicates

public static Predicate parsePredicates(String expression,
                                        String property)

parseSimplePredicate

public static Predicate parseSimplePredicate(String property,
                                             String value)
