,SchemaComponent.INCOMPLETE
-
getBaseType
Get the base type- Specified by:
getBaseType
in interfaceSchemaType
- Returns:
- AnyType
-
getKnownBaseType
Returns the base type that this type inherits from. This method can be used to get the base type of a type that is known to be valid.- Returns:
- the base type.
- Throws:
IllegalStateException
-
isComplexType
public boolean isComplexType()Test whether this SchemaType is a complex type- Specified by:
isComplexType
in interfaceSchemaType
- Returns:
- true if this SchemaType is a complex type
-
isSimpleType
public boolean isSimpleType()Test whether this SchemaType is a simple type- Specified by:
isSimpleType
in interfaceSchemaType
- Returns:
- true if this SchemaType is a simple type
-
getFingerprint
public int getFingerprint()Get the fingerprint of the name of this type- Specified by:
getFingerprint
in interfaceSchemaType
- Returns:
- the fingerprint.
-
getNameCode
public int getNameCode()Get the namecode of the name of this type. This includes the prefix from the original type declaration: in the case of built-in types, there may be a conventional prefix or there may be no prefix.- Specified by:
getNameCode
in interfaceSchemaType
-
getDescription
Get a description of this type for use in diagnostics- Specified by:
getDescription
in interfaceSchemaType
- Returns:
- the string "xs:anyType"
-
getDisplayName
Get the display name of the type: that is, a lexical QName with an arbitrary prefix- Specified by:
getDisplayName
in interfaceSchemaType
- Returns:
- a lexical QName identifying the type
-
isSameType
Test whether this is the same type as another type. They are considered to be the same type if they are derived from the same type definition in the original XML representation (which can happen when there are multiple includes of the same file)- Specified by:
isSameType
in interfaceSchemaType
-
getTypedValue
Get the typed value of a node that is annotated with this schema type. This shouldn't happen: nodes are never annotated as xs:anySimpleType; but if it does happen, we treat it as if it were untypedAtomic.- Specified by:
getTypedValue
in interfaceSchemaType
- Parameters:
node
- the node whose typed value is required- Returns:
- an iterator returning a single untyped atomic value, equivalent to the string value of the node.
-
atomize
Get the typed value of a node that is annotated with this schema type. The result of this method will always be consistent with the methodgetTypedValue(net.sf.saxon.om.NodeInfo)
. However, this method is often more convenient and may be more efficient, especially in the common case where the value is expected to be a singleton.- Specified by:
atomize
in interfaceSchemaType
- Parameters:
node
- the node whose typed value is required- Returns:
- the typed value.
- Since:
- 8.5
-
checkTypeDerivationIsOK

checkTypeDerivationIsOK
in interfaceSchemaType
- Parameters:
type
- the type from which this type is derivedblock
- the derivations that are blocked by the relevant element declaration- Throws:
SchemaException
- if the derivation is not allowed

isAtomicType

isAtomicType
in interfaceSchemaType
- Specified by:
isAtomicType
in interfaceSimpleType
- Returns:

-
isAnonymousType
public boolean isAnonymousType()Description copied from interface:SchemaType
Test whether this is an anonymous type- Specified by:
isAnonymousType
in interfaceSchemaType
- Returns:

value
- the input string to be checkednsResolver
- a namespace resolver used to resolve namespace prefixes if the type is namespace sensitive. The value supplied may be null; in this case any namespace-sensitive content will throw an UnsupportedOperationException.nameChecker
