public List<StaticOperandImpl> getOperand2()
-
simplify
public ConstraintImpl simplify()
Description copied from class:ConstraintImpl
Simplify the expression if possible, for example by removing duplicate expressions. For example, "x=1 or x=1" should be simplified to "x=1".- Overrides:
simplify
in classConstraintImpl
- Returns:
- the simplified constraint, or "this" if it is not possible to simplify
-
getPropertyExistenceConditions
public Set<PropertyExistenceImpl> 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
public Set<SelectorImpl> 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)
-
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
-
restrict
public void restrict(FilterImpl f)
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
public void restrictPushDown(SelectorImpl s)
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
-
equals
public boolean equals(Object that)
- Overrides:
equals
in classConstraintImpl
-
hashCode
public int hashCode()
- Overrides:
hashCode
in classConstraintImpl
-
copyOf
public org.apache.jackrabbit.oak.query.ast.AstElement copyOf()
- Returns:
- a clone of self. Default implementation in
AstElement
returns same reference tothis
.
-
setQuery
public void setQuery(QueryImpl query)
-
normalizePropertyName
protected String normalizePropertyName(String propertyName)
Normalize the property name (including namespace remapping). Asterisks are kept.- Parameters:
propertyName
- the property name to normalize- Returns:
- the normalized (oak-) property name
-
normalizePath
protected String normalizePath(String path)
Validate and normalize the path.- Parameters:
path
- the path to validate- Returns:
- the validated and normalized path
-
convertValueToType
protected PropertyValue convertValueToType(PropertyValue v, PropertyValue targetType)
