 net.sf.saxon.expr.ComputedExpression
net.sf.saxon.expr.Assignation
All known Subclasses: net.sf.saxon.expr.LetExpression, net.sf.saxon.expr.ForExpression, net.sf.saxon.expr.QuantifiedExpression,
| Assignation | | abstract public class Assignation extends ComputedExpression implements Binding(Code) | | Assignation is an abstract superclass for the kinds of expression
that declare range variables: for, some, and every.
|
| nameCode | | protected int nameCode(Code) | | |
| slotNumber | | protected int slotNumber(Code) | | |
| extendBindingList | | protected Binding[] extendBindingList(Binding[] in)(Code) | | Extend an array of variable bindings to include the binding(s) defined in this expression
|
| getLocalSlotNumber | | public int getLocalSlotNumber()(Code) | | If this is a local variable held on the local stack frame, return the corresponding slot number.
In other cases, return -1.
|
| getRequiredSlots | | public int getRequiredSlots()(Code) | | Get the number of slots required. Normally 1, except for a FOR expression with an AT clause, where it is 2.
|
| getVariableFingerprint | | public int getVariableFingerprint()(Code) | | |
| getVariableName | | public String getVariableName(NamePool pool)(Code) | | Get the display name of the range variable, for diagnostics only
|
| getVariableNameCode | | public int getVariableNameCode()(Code) | | |
| isAssignable | | final public boolean isAssignable()(Code) | | Test whether it is permitted to assign to the variable using the saxon:assign
extension element. This will only be for an XSLT global variable where the extra
attribute saxon:assignable="yes" is present.
|
| isGlobal | | final public boolean isGlobal()(Code) | | Indicate whether the binding is local or global. A global binding is one that has a fixed
value for the life of a query or transformation; any other binding is local.
|
| iterateSubExpressions | | public Iterator iterateSubExpressions()(Code) | | Get the immediate subexpressions of this expression
|
| promoteWhereClause | | protected Expression promoteWhereClause(Binding positionBinding)(Code) | | Promote a WHERE clause whose condition doesn't depend on the variable being bound.
This rewrites an expression of the form
let $i := SEQ return if (C) then R else ()
to the form:
if (C) then (let $i := SEQ return R) else ()
|
| setAction | | public void setAction(Expression action)(Code) | | Add the "return" or "satisfies" expression, and fix up all references to the
range variable that occur within that expression
Parameters:
action - the expression that occurs after the "return" keyword of a "for"expression, the "satisfies" keyword of "some/every", or the ":=" operator ofa "let" expression.This method must be called after calling setVariableDeclaration() |
| setSequence | | public void setSequence(Expression sequence)(Code) | | Set the "sequence" expression - the one to which the variable is bound
|
| setSlotNumber | | public void setSlotNumber(int nr)(Code) | | Set the slot number for the range variable
|
| suppressValidation | | public void suppressValidation(int validationMode)(Code) | | Suppress validation on contained element constructors, on the grounds that the parent element
is already performing validation. The default implementation does nothing.
