Class UseWhenStaticContext

  • All Implemented Interfaces:
    java.io.Serializable, javax.xml.transform.SourceLocator, Container, StaticContext, XSLTStaticContext
    public class UseWhenStaticContext
extends AbstractStaticContext
implements XSLTStaticContext, Container
    This class implements the static context used for evaluating use-when expressions in XSLT 2.0 A new instance of this class is created for each use-when expression encountered; there are therefore no issues with reusability. The class provides a Container for the expression as well as the static context information; the Executable contains the single XPath expression only, and is created for the purpose.

                            NamespaceResolver namespaceContext)
        Create a static context for evaluating use-when expressions

        Specified by:
        getExecutable in interface Container
        Returns:
        the Executable

      • issueWarning

        public void issueWarning​(java.lang.String s,
                         javax.xml.transform.SourceLocator locator)

        Overrides:
        issueWarning in class AbstractStaticContext
        Parameters:
        s - The warning message. This should not contain any prefix such as "Warning".
        locator - the location of the construct in question. May be null.

      • getSystemId

        public java.lang.String getSystemId()
        Get the System ID of the container of the expression. This is the containing entity (file) and is therefore useful for diagnostics. Use getBaseURI() to get the base URI, which may be different.
        Specified by:
        getSystemId in interface javax.xml.transform.SourceLocator
        Specified by:
        getSystemId in interface StaticContext
        Overrides:
        getSystemId in class AbstractStaticContext
        Returns:
        "" always

      • getContainerGranularity

        public int getContainerGranularity()
        Get the granularity of the container.
        Specified by:
        getContainerGranularity in interface Container
        Returns:
        0 for a temporary container created during parsing; 1 for a container that operates at the level of an XPath expression; 2 for a container at the level of a global function or template

      • getURIForPrefix

        public java.lang.String getURIForPrefix​(java.lang.String prefix)
                                 throws XPathException
        Get the URI for a namespace prefix. The default namespace is NOT used when the prefix is empty.
        Specified by:
        getURIForPrefix in interface StaticContext
        Parameters:
        prefix - The prefix
        Returns:
        the corresponding namespace URI
        Throws:
        XPathException - if the prefix is not declared

      • bindVariable

        public Expression bindVariable​(StructuredQName qName)
                        throws XPathException
        Bind a variable used in this element to the XSLVariable element in which it is declared
        Specified by:
        bindVariable in interface StaticContext
        Parameters:
        qName - the name of the variable
        Returns:
        an expression representing the variable reference, This will often be a VariableReference, suitably initialized to refer to the corresponding variable declaration, but in general it can be any expression.
        Throws:
        XPathException

      • getCollation

        public StringCollator getCollation​(java.lang.String name)
        Get a named collation.
        Specified by:
        getCollation in interface StaticContext
        Overrides:
        getCollation in class AbstractStaticContext
        Parameters:
        name - The name of the required collation. Supply null to get the default collation.
        Returns:
        the collation; or null if the required collation is not found.

      • isImportedSchema

        public boolean isImportedSchema​(java.lang.String namespace)
        Determine whether a Schema for a given target namespace has been imported. Note that the in-scope element declarations, attribute declarations and schema types are the types registered with the (schema-aware) configuration, provided that their namespace URI is registered in the static context as being an imported schema namespace. (A consequence of this is that within a Configuration, there can only be one schema for any given namespace, including the null namespace).
        Specified by:
        isImportedSchema in interface StaticContext
        Parameters:
        namespace - the target namespace in question
        Returns:
        true if the given namespace has been imported

      • getImportedSchemaNamespaces

        public java.util.Set<java.lang.String> getImportedSchemaNamespaces()
        Get the set of imported schemas
        Specified by:
        getImportedSchemaNamespaces in interface StaticContext
        Returns:
        a Set, the set of URIs representing the names of imported schemas

      • isAllowedBuiltInType

        public boolean isAllowedBuiltInType​(BuiltInAtomicType type)
        Determine whether a built-in type is available in this context. This method caters for differences between host languages as to which set of types are built in.
        Specified by:
        isAllowedBuiltInType in interface StaticContext
        Overrides:
        isAllowedBuiltInType in class AbstractStaticContext
        Parameters:
        type - the supposedly built-in type. This will always be a type in the XS or XDT namespace.
        Returns:
        true if this type can be used in this static context

      • getNamespaceResolver

        public NamespaceResolver getNamespaceResolver()
        Get a namespace resolver to resolve the namespaces declared in this static context.
        Specified by:
        getNamespaceResolver in interface StaticContext
        Returns:
        a namespace resolver.
