Class ValueConstraint

java.lang.Object
  org.apache.jackrabbit.spi.commons.nodetype.ValueConstraint

public abstract class ValueConstraint
extends Object

ValueConstraint and its subclasses are used to check the syntax of a value constraint and to test if a specific value satisfies it.

Method Summary

static void	checkValueConstraints(QPropertyDefinition pd, QValue[] values) Tests if the value constraints defined in the property definition pd are satisfied by the the specified values.

boolean	equals(Object other)
String	getDefinition(NamePathResolver resolver) For constraints that are not namespace prefix mapping sensitive this method returns the same result as getQualifiedDefinition().

Method Detail

getDefinition

public String getDefinition(NamePathResolver resolver)

For constraints that are not namespace prefix mapping sensitive this method returns the same result as getQualifiedDefinition().

Those that are namespace prefix mapping sensitive (e.g. NameConstraint, PathConstraint and ReferenceConstraint) use the given nsResolver to reflect the current mapping in the returned value. In other words: subclasses, that need to make a conversion to JCR value must overwrite this and return a value that has all qualified names and path elements resolved.

Parameters:

resolver -

Returns:

the definition of this constraint.

See Also:

getQualifiedDefinition()

getQualifiedDefinition

public String getQualifiedDefinition()

By default the qualified definition is the same as the JCR definition.

Returns:

the qualified definition String

See Also:

getDefinition(NamePathResolver)

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Returns the hashCode of the definition String

Overrides:

hashCode in class Object

Returns:

the hashCode of the definition String

Object.hashCode()

create

public static ValueConstraint create(int type,
                                     String qualifiedDefinition)
                              throws InvalidConstraintException

Create a new ValueConstraint from the String representation. Note, that the definition must be in the qualified format in case the type indicates PropertyType.NAME, PropertyType.PATH or PropertyType.REFERENCE

Parameters:

type -

qualifiedDefinition -

Returns:

Throws:

InvalidConstraintException

create

public static ValueConstraint create(int type,
                                     String definition,
                                     NamePathResolver resolver)
                              throws InvalidConstraintException

Parameters:

type -

definition -

resolver -

Returns:

Throws:

InvalidConstraintException

checkValueConstraints

public static void checkValueConstraints(QPropertyDefinition pd,
                                         QValue[] values)
                                  throws ConstraintViolationException,
                                         RepositoryException

Tests if the value constraints defined in the property definition pd are satisfied by the the specified values.

Note that the protected flag is not checked. Also note that no type conversions are attempted if the type of the given values does not match the required type as specified in the given definition.

Parameters:

pd -

values -

Throws:

ConstraintViolationException

RepositoryException
