public class SaxonForEachMember
extends StyleElement
implements ScopedBindingElement

Handler for saxon:for-each-member elements in stylesheet. The saxon:for-each-member element has mandatory attributes select and bind-to. The select expression must return an array. For each member of this array it binds the variable named in the bind-to attribute, and executes the body of the instruction with this additional variable binding.

Constructor Detail

SaxonForEachMember

public SaxonForEachMember()

Method Detail

isInstruction

public boolean isInstruction()

Determine whether this node is an instruction.

Overrides:

isInstruction in class StyleElement

Returns:

true - it is an instruction

mayContainSequenceConstructor

public boolean mayContainSequenceConstructor()

Determine whether this type of element is allowed to contain a template-body

Overrides:

mayContainSequenceConstructor in class StyleElement

Returns:

true: yes, it may contain a template-body

prepareAttributes

public void prepareAttributes()

Description copied from class: StyleElement

Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass

Specified by:

prepareAttributes in class StyleElement

validate

public void validate(ComponentDeclaration decl)
              throws XPathException

Description copied from class: StyleElement

Check that the stylesheet element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.

Overrides:

validate in class StyleElement

Parameters:

decl - the declaration to be validated

Throws:

XPathException - if any error is found during validation

compile

public Expression compile(Compilation exec,
                          ComponentDeclaration decl)
                   throws XPathException

Description copied from class: StyleElement

Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.

Overrides:

compile in class StyleElement

Parameters:

exec - the compilation episode

decl - the containing top-level declaration, for example xsl:function or xsl:template

Returns:

either a ComputedExpression, or null. The value null is returned when compiling an instruction that returns a no-op, or when compiling a top-level object such as an xsl:template that compiles into something other than an instruction.

Throws:

XPathException - if validation fails

hasImplicitBinding

protected SourceBinding hasImplicitBinding(StructuredQName name)

Ask whether this particular element implicitly binds a given variable (used for xsl:accumulator-rule)

Overrides:

hasImplicitBinding in class StyleElement

Parameters:

name -

allocateSlots

public int allocateSlots(SlotManager slotManager,
                         int nextFree)

Allocate slots to any variables used within the pattern

Specified by:

allocateSlots in interface ScopedBindingElement

Parameters:

slotManager - the slot manager representing the stack frame for local variables

nextFree - the next slot that is free to be allocated

Returns:

the next slot that is free to be allocated
