                            throws InvalidDataException

Create a new annotation restriction using a simple expression: annotation operator value.

Parameters:

alias - The alias of a joined item where the annotations are located or null to use the root entity of the query

annotationType - The annotation type to use in the query

operator - The operator, it must be one of the expression operators, EQ, NEQ, etc., not a boolean operator, AND, OR, etc.

value - The value to use in the query, it must be of the correct value type for the annotation as defined by the AnnotationType.getValueType() property

includeInheriting - If items inherting the annotation should be returned by the query or not

Throws:

InvalidDataException - If any of the parameters are null or not follow the rules above.

Method Detail

getRestrictionSql

String getRestrictionSql(Query query,
                         DbControl dc)
                   throws BaseException

Description copied from class: AnnotationRestriction

Get an SQL fragment that includes the actual restriction. Use 'v.value' to access the annotation value. Avoid including literal values originating from a user, especially strings, since it may lead to security holes unless the values are checked for dangerous characters. Use a parameter placeholder instead. A parameter placeholder is a colon (:) followed by a name. Example:

v.value = :theValue

                The setRestrictionParameters method is called to 
                allow the subclass to set the value of the parameters specified
                in the SQL fragment.


Specified by:
getRestrictionSql in class AnnotationRestriction


Parameters:
query - The query object we are about to execute
Returns:
An SQL fragment, or null if no additional restriction is required
Throws:
BaseException
See Also:
AnnotationRestriction.setRestrictionParameters(SQLQuery)

setRestrictionParameters

void setRestrictionParameters(SQLQuery query)

Description copied from class: AnnotationRestriction

Set the value for all parameters defined in the SQL fragment returned by AnnotationRestriction.getRestrictionSql(Query, DbControl).

Specified by:

setRestrictionParameters in class AnnotationRestriction

Parameters:

query - The Hibernate SQLQuery object which is used to query the database

equals

public boolean equals(Object other)

This restriction is equal to another AnnotationSimpleRestriction if they have the same annotation type, operator, list of values and inheritance setting.

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class AnnotationRestriction
