startValueScopeFor
public void startValueScopeFor(IdentityConstraint identityConstraint,
int initialDepth)
- Start the value scope for the specified identity constraint. This
method is called when the selector matches in order to initialize
the value store.
- Parameters:
identityConstraint
- The identity constraint.initialDepth
- the depth at which the selector began matching
activateField
public XPathMatcher activateField(Field field,
int initialDepth)
- Request to activate the specified field. This method returns the
matcher for the field.
It's also important for the implementor to ensure that the Field realizes that
it is permitted to match a value--that is, to call the field's setMayMatch(boolean) method.
- Parameters:
field
- The field to activate.initialDepth
- the 0-indexed depth in the instance document at which the Selector began to match.
endValueScopeFor
public void endValueScopeFor(IdentityConstraint identityConstraint,
int initialDepth)
- Ends the value scope for the specified identity constraint.
- Parameters:
identityConstraint
- The identity constraint.initialDepth
- the 0-indexed depth where the Selector began to match.
