net.sf.saxon.instruct.Instruction
net.sf.saxon.instruct.While
| While | | public class While extends Instruction (Code) | | Handler for saxon:while elements in stylesheet.
The saxon:while element has a mandatory attribute test, a boolean expression.
The content is output repeatedly so long as the test condition is true.
|
| createsNewNodes | | final public boolean createsNewNodes()(Code) | | Determine whether this instruction creates new nodes.
This implementation returns true if the "action" creates new nodes.
(Nodes created by the condition can't contribute to the result).
|
| display | | public void display(int level, NamePool pool, PrintStream out)(Code) | | Diagnostic print of expression structure. The expression is written to the System.err
output stream
Parameters:
level - indentation level for this expression
Parameters:
out - |
| getActionExpression | | public Expression getActionExpression()(Code) | | Get the action expression (the content of the for-each)
|
| getInstructionNameCode | | public int getInstructionNameCode()(Code) | | Get the name of this instruction for diagnostic and tracing purposes
the string "saxon:while" |
| getItemType | | public ItemType getItemType(TypeHierarchy th)(Code) | | Get the item type of the items returned by evaluating this instruction
the static item type of the instruction
Parameters:
th - |
| iterateSubExpressions | | public Iterator iterateSubExpressions()(Code) | | Get all the XPath expressions associated with this instruction
(in XSLT terms, the expression present on attributes of the instruction,
as distinct from the child instructions in a sequence construction)
|
| simplify | | public Expression simplify(StaticContext env) throws XPathException(Code) | | Simplify an expression. This performs any static optimization (by rewriting the expression
as a different expression).
exception:
XPathException - if an error is discovered during expressionrewriting the simplified expression |
