Constructor Detail

PrimitiveDatatype

public PrimitiveDatatype(Class<AV> instanceClass,
                         String id,
                         String functionIdPrefix,
                         net.sf.saxon.s9api.ItemType xpathDatatype)
                  throws NullPointerException

Datatype constructor

Parameters:

instanceClass - (non-null) Java class used as implementation for this datatype, i.e. all values of this datatype are instances of valueClass.

id - (non-null) datatype ID

functionIdPrefix - (non-null) prefix of ID of any standard generic (e.g. bag/set) function built on this datatype, e.g. 'urn:oasis:names:tc:xacml:1.0:function:string' for string datatype

Throws:

NullPointerException - if instanceClass == null || id == null || functionIdPrefix == null.

Method Detail

isInstance

public final boolean isInstance(Value val)

Description copied from class: Datatype

This method returns true if the specified value argument is an instance of the represented datatype; it returns false otherwise

Specified by:

isInstance in class Datatype<AV extends PrimitiveValue>

Parameters:

val - value to be checked

Returns:

true iff val is an instance of this datatype

cast

public final AV cast(Value val)
              throws ClassCastException

Description copied from class: Datatype

Casts a value to the class or interface represented by this datatype.

Specified by:

cast in class Datatype<AV extends PrimitiveValue>

Parameters:

val - value to be cast

Returns:

the value after casting, or null if val is null

Throws:

ClassCastException - if the value is not null and is not assignable to the type V.

newArray

public final AV[] newArray(int length)

Description copied from class: Datatype

Creates a new array with this as component type

Specified by:

newArray in class Datatype<AV extends PrimitiveValue>

Parameters:

length - length of the new array

Returns:

the new array

getTypeParameter

public final Optional<Datatype<?>> getTypeParameter()

Description copied from class: Datatype

Return type parameter e.g. the bag element datatype (datatype of every element in a bag of this datatype); null if this is a primitive type (no sub-elements)

Specified by:

getTypeParameter in class Datatype<AV extends PrimitiveValue>

Returns:

datatype parameter, null for primitive datatypes

getInstanceClass

public final Class<AV> getInstanceClass()

Get class of instances of this datatype

Returns:

class of instances of this datatype

getArrayClass

public final Class<AV[]> getArrayClass()

Get class of array of instances of this datatype

Returns:

class of array where the component type is this datatype
