UseWhenStaticContext
public UseWhenStaticContext(Configuration config, NamespaceResolver namespaceContext)
Create a static context for evaluating use-when expressions- Parameters:
config
- the Saxon configurationnamespaceContext
- the namespace context in which the use-when expression appears
-
-
Method Detail
-
issueWarning
public void issueWarning(java.lang.String s, javax.xml.transform.SourceLocator locator)
Issue a compile-time warning- Specified by:
issueWarning
in interfaceStaticContext
- Overrides:
issueWarning
in classAbstractStaticContext
- 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 interfacejavax.xml.transform.SourceLocator
- Specified by:
getSystemId
in interfaceStaticContext
- Overrides:
getSystemId
in classAbstractStaticContext
- Returns:
- "" always
-
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 interfaceStaticContext
- Parameters:
prefix
- The prefix- Returns:
- the corresponding namespace URI
- Throws:
XPathException
- if the prefix is not declared
-
bindVariable
public VariableReference 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 interfaceStaticContext
- Parameters:
qName
- the name of the variable- Returns:
- a VariableReference representing the variable reference, suitably initialized to refer to the corresponding variable declaration
- Throws:
XPathException
-
getFunctionLibrary
public FunctionLibrary getFunctionLibrary()
Get the function library containing all the in-scope functions available in this static context- Specified by:
getFunctionLibrary
in interfaceStaticContext
- Overrides:
getFunctionLibrary
in classAbstractStaticContext
- Returns:
- the function library
-
getCollation
public StringCollator getCollation(java.lang.String name)
Get a named collation.- Specified by:
getCollation
in interfaceStaticContext
- Overrides:
getCollation
in classAbstractStaticContext
- 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.
-
getDefaultCollationName
public java.lang.String getDefaultCollationName()
Get the name of the default collation.- Specified by:
getDefaultCollationName
in interfaceStaticContext
- Overrides:
getDefaultCollationName
in classAbstractStaticContext
- Returns:
- the name of the default collation; or the name of the codepoint collation if no default collation has been defined
-
getDefaultFunctionNamespace
public java.lang.String getDefaultFunctionNamespace()
Get the default function namespace- Specified by:
getDefaultFunctionNamespace
in interfaceStaticContext
- Overrides:
getDefaultFunctionNamespace
in classAbstractStaticContext
- Returns:
- the default namesapce for functions
-
isInBackwardsCompatibleMode
public boolean isInBackwardsCompatibleMode()
Determine whether Backwards Compatible Mode is used- Specified by:
isInBackwardsCompatibleMode
in interfaceStaticContext
- Overrides:
isInBackwardsCompatibleMode
in classAbstractStaticContext
- Returns:
- true if XPath 1.0 backwards compatibility has been selected (by default, it is false)
-
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 interfaceStaticContext
- Parameters:
namespace
- the target namespace in question- Returns:
- true if the given namespace has been imported
-
getImportedSchemaNamespaces
public java.util.Set getImportedSchemaNamespaces()
Get the set of imported schemas- Specified by:
getImportedSchemaNamespaces
in interfaceStaticContext
- 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 interfaceStaticContext
- Overrides:
isAllowedBuiltInType
in classAbstractStaticContext
- 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 interfaceStaticContext
- Returns:
- a namespace resolver.
-
isElementAvailable
public boolean isElementAvailable(java.lang.String qname) throws XPathException
Determine if an extension element is available- Specified by:
isElementAvailable
in interfaceXSLTStaticContext
- Throws:
XPathException
- if the name is invalid or the prefix is not declared
-
-
