Method Detail

values
public static Operator[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (Operator c : Operator.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static Operator valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
- if this enum type has no constant with the specified nameNullPointerException
- if the argument is null
-
comparison
public Comparison comparison(QueryObjectModelFactory factory, DynamicOperand left, StaticOperand right) throws RepositoryException
Returns a comparison between the given operands using this operator.- Parameters:
factory
- factory for creating the comparisonleft
- operand on the left hand sideright
- operand on the right hand side- Returns:
- comparison
- Throws:
RepositoryException
- if the comparison can not be created
-
formatXpath
public String formatXpath(String a, String b)
Formats an XPath constraint with this operator and the given operands. The operands are simply used as-is, without any quoting or escaping.- Parameters:
a
- first operandb
- second operand- Returns:
- XPath constraint,
a op b
orjcr:like(a, b)
forLIKE
-
formatSql
public String formatSql(String a, String b)
Formats an SQL constraint with this operator and the given operands. The operands are simply used as-is, without any quoting or escaping.- Parameters:
a
- first operandb
- second operand- Returns:
- SQL constraint,
a op b
-
toString
public String toString()
Returns the JCR 2.0 name of this query operator.- Overrides:
toString
in classEnum<Operator>
- Returns:
- JCR name of this operator

getAllQueryOperators
public static String[] getAllQueryOperators()
Returns an array of the names of all the JCR 2.0 query operators.- Returns:
- names of all query operators
