Return true if this is an external object type, that is, a Saxon-defined type for external Java or .NET objects

getFingerprint

public int getFingerprint()

Get the fingerprint of the name of this type

Specified by:

getFingerprint in interface SchemaType

Returns:

the fingerprint. Returns an invented fingerprint for an anonymous type.

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, this will be a conventional prefix such as "xs" or "xdt".

Specified by:

isAnonymousType

public boolean isAnonymousType()

Test whether this is an anonymous type

Specified by:

Returns:

true if this SchemaType is an anonymous type

setNameCode

public void setNameCode(int nameCode)

Set the nameCode of the name of this type. For internal use only.

Parameters:

nameCode - the nameCode allocated in the namepool for this schema

getBaseTypeReference

public TypeReference getBaseTypeReference()

Get the reference to the base type. The result is never null, except in the case of the type AnyType, which is the root of the type hierarchy.

getBaseTypeFingerprint

public int getBaseTypeFingerprint()

Get the fingerprint of the name of the base type of this type

Returns:

the fingerprint. Return an invented fingerprint for an anonymous type.

getLocalName

public String getLocalName()

Deprecated. since 9.0: use the equivalent method getName()

Get the local name of this type

Returns:

the local part of the name, or null if the type is anonymous

getDisplayName

public String getDisplayName()

Get the display name of the type: that is, a lexical QName with an arbitrary prefix

Specified by:

getDisplayName in interface SchemaType

Returns:

a lexical QName identifying the type

isComplexType

public final boolean isComplexType()

Test whether this SchemaType is a complex type

Specified by:

isComplexType in interface SchemaType

Returns:

true if this SchemaType is a complex type

getBlock

public int getBlock()

Returns the value of the 'block' attribute for this type, as a bit-signnificant integer with fields such as SchemaType.DERIVATION_LIST and SchemaType.DERIVATION_EXTENSION

Specified by:

getBlock in interface SchemaType

Returns:

the value of the 'block' attribute for this type

getNamePool

public NamePool getNamePool()

Get the NamePool in which the name of this type is defined

getBaseType

public SchemaType getBaseType()
                       throws UnresolvedReferenceException

Returns the base type that this type inherits from. If this type is a Simpletype that is a built in primitive type then null is returned.

Specified by:

getBaseType in interface SchemaType

Returns:

the base type.

Throws:

UnresolvedReferenceException - if this type has no known base type. This can only arise during schema construction, since a type with an unknown base type cannot be used for validation

setBaseTypeReference

public void setBaseTypeReference(TypeReference baseType)

Sets the base type for this datatype. For internal use only.

Parameters:

baseType - the base type which this type inherits from

getDerivationMethod

public int getDerivationMethod()

Gets the integer code of the derivation method used to derive this type from its parent. Returns zero for primitive types.

Specified by:

getDerivationMethod in interface SchemaType

Returns:

a numeric code representing the derivation method, for example SchemaType.DERIVATION_RESTRICTION

allowsDerivation

public boolean allowsDerivation(int derivation)

Determines whether derivation (of a particular kind) from this type is allowed, based on the "final" property

Specified by:

allowsDerivation in interface SchemaType

Parameters:

derivation - the kind of derivation, for example SchemaType.DERIVATION_LIST

Returns:

true if this kind of derivation is allowed

setDerivationMethodName

public void setDerivationMethodName(String method)
                             throws SchemaException

In the case of a type known to be defined immediately within an element or attribute declaration, it is a phrase that identifies the containing declaration. In other cases, it is a phrase of the form "defined at line L of URI". The description is designed to be inserted in a context such as "the type X is ..."

Specified by:

getDescription in interface SchemaType

Returns:

text identifing the type, for use in a phrase such as "the type XXXX".

getContainingDeclarationName

public int getContainingDeclarationName()

Get the name of the containing element or attribute declaration, if any (and if known).

Returns:

the name of the containing declaration, as a NamePool fingerprint.

containingDeclarationIsElement

public boolean containingDeclarationIsElement()

Returns:

true if the containin declaration is an element declaration, false if it is an attribute

isSameType

Specified by:

isSameType in interface SchemaType

Parameters:

other - the other type

Returns:

true if this is the same type as other
