Method Summary |
Tristate |
appliesTo(org.outerj.daisy.repository.Document document)
Checks if this conditionl expression could evaluate to true
for a document, without really knowing everything about the document. |

evaluate
public boolean evaluate(org.outerj.daisy.repository.Document document,
org.outerj.daisy.repository.Version version,
org.outerj.daisy.repository.query.EvaluationContext evaluationContext)
throws org.outerj.daisy.repository.query.QueryException
- Description copied from interface:
PredicateExpr
- Evaluates the expression for the given document and version. The version
parameter is allowed to be null, in which case version-dependent information
will be retrieved from the document object.
- Throws:
org.outerj.daisy.repository.query.QueryException
generateSql
public void generateSql(java.lang.StringBuffer sql,
SqlGenerationContext context)
throws org.outerj.daisy.repository.query.QueryException
- Throws:
org.outerj.daisy.repository.query.QueryException
bindSql
public int bindSql(java.sql.PreparedStatement stmt,
int bindPos,
org.outerj.daisy.repository.query.EvaluationContext evaluationContext)
throws java.sql.SQLException,
org.outerj.daisy.repository.query.QueryException
bindPos
- the binding position on which to bind the next value
- Returns:
- the next binding position
- Throws:
java.sql.SQLException
org.outerj.daisy.repository.query.QueryException
isAclAllowed
public AclConditionViolation isAclAllowed()
- Description copied from interface:
PredicateExpr
- Checks if this PredicateExpr only uses stuff allowed in ACL object conditions.
Returns null if successfull.
appliesTo
public Tristate appliesTo(org.outerj.daisy.repository.Document document)
throws org.outerj.daisy.repository.query.QueryException
- Description copied from interface:
PredicateExpr
- Checks if this conditionl expression could evaluate to true
for a document, without really knowing everything about the document.
The supplied Document object only needs to return the document type
and collections, the other methods do not need to be implemented.
The result can be:
- yes, if the expression is guaranteed to evaluate
to true for such a document. For example, the simple
expression 'true' will always be true regardless
of the document.
- no,if the expression is guaranteed to evaluate to
false for such a document. For example, the expression
test "documentType = 'abc'" but the supplied document
object is of another type.
- maybe, if the epxression could apply but the exact
outcome depends on further information. For example,
when the expression depends on the value of a field.
- Throws:
org.outerj.daisy.repository.query.QueryException
