    • Method Detail

      • getReturnedItemType

        protected ItemType getReturnedItemType()
        Determine the type of item returned by this instruction (only relevant if it is an instruction).
        Overrides:
        getReturnedItemType in class StyleElement
        Returns:
        the item type returned. This is null for a variable: we are not interested in the type of the variable, but in what the xsl:variable constributes to the result of the sequence constructor it is part of.

      • 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

      • allowsAsAttribute

        protected boolean allowsAsAttribute()

      • allowsTunnelAttribute

        protected boolean allowsTunnelAttribute()

      • allowsValue

        protected boolean allowsValue()

      • allowsRequired

        protected boolean allowsRequired()

      • isAssignable

        public boolean isAssignable()
        Test whether it is permitted to assign to the variable using the saxon:assign extension element. This will only be true if the extra attribute saxon:assignable="yes" is present.

      • isTunnelParam

        public boolean isTunnelParam()

      • isRequiredParam

        public boolean isRequiredParam()

      • isGlobal

        public boolean isGlobal()

      • getVariableName

        public java.lang.String getVariableName()
        Get the display name of the variable.

      • setRedundant

        public void setRedundant()
        Mark this global variable as redundant. This is done before prepareAttributes is called.

      • getVariableFingerprint

        public int getVariableFingerprint()
        Get the fingerprint of the variable name

      • prepareAttributes

        public void prepareAttributes()
                       throws XPathException
        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
        Throws:
        XPathException

      • validate

        public void validate()
              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
        Throws:
        XPathException

      • checkAgainstRequiredType

        protected void checkAgainstRequiredType​(SequenceType required)
                                 throws XPathException
        Check the supplied select expression against the required type.
        Parameters:
        required - The type required by the variable declaration, or in the case of xsl:with-param, the signature of the called template
        Throws:
        XPathException

      • setReferenceCount

        protected void setReferenceCount​(GeneralVariable var)
