evaluate
public boolean evaluate()Description copied from class:ConstraintImpl
Evaluate the result using the currently set values.- Specified by:
evaluate
in classConstraintImpl
- Returns:
- true if the constraint matches
-
getPropertyExistenceConditions
Description copied from class:ConstraintImpl
Get the set of property existence conditions that can be derived for this condition. For example, for the condition "x=1 or x=2", the property existence condition is "x is not null". For the condition "x=1 or y=2", there is no such condition. For the condition "x=1 and y=1", there are two (x is not null, and y is not null).- Specified by:
getPropertyExistenceConditions
in classConstraintImpl
- Returns:
- the common property existence condition (possibly empty)
-
getSelectors
Description copied from class:ConstraintImpl
Get the set of selectors for the given condition.- Specified by:
getSelectors
in classConstraintImpl
- Returns:
- the set of selectors (possibly empty)

bindSelector

restrict
Description copied from class:ConstraintImpl
Apply the condition to the filter, further restricting the filter if possible. This may also verify the data types are compatible, and that paths are valid.- Specified by:
restrict
in classConstraintImpl
- Parameters:
f
- the filter
-
restrictPushDown
Description copied from class:ConstraintImpl
Push as much of the condition down to this selector, further restricting the selector condition if possible. This is important for a join: for example, the query "select * from a inner join b on a.x=b.x where a.y=1 and b.y=1", the condition "a.y=1" can be pushed down to "a", and the condition "b.y=1" can be pushed down to "b". That means it is possible to use an index in this case.- Specified by:
restrictPushDown
in classConstraintImpl
- Parameters:
s
- the selector
-
copyOf
public org.apache.jackrabbit.oak.query.ast.AstElement copyOf()- Returns:
- a clone of self. Default implementation in
AstElement
returns same reference tothis

normalizePropertyName
Normalize the property name (including namespace remapping). Asterisks are kept.- Parameters:
propertyName
- the property name to normalize- Returns:
- the normalized (oak-) property name
-
normalizePath
Validate and normalize the path.- Parameters:
path
- the path to validate- Returns:
- the validated and normalized path
-
convertValueToType
-
getLocalPath
Calculate the session local path (the path excluding the workspace name) if possible.- Parameters:
path
- the absolute path- Returns:
- the session local path, or null if not within this workspace
