Class XdmAtomicValue

public class XdmAtomicValue extends XdmItem

The class XdmAtomicValue represents an item in an XPath 2.0 sequence that is an atomic value. The value may belong to any of the 19 primitive types defined in XML Schema, or to a type derived from these primitive types, or the XPath 2.0 type xs:untypedAtomic. The type may be either a built-in type or a user-defined type.

An XdmAtomicValue is immutable.

Constructor Detail

XdmAtomicValue

protected XdmAtomicValue(AtomicValue value)

XdmAtomicValue

public XdmAtomicValue(boolean value)
Create an xs:boolean atomic value

Parameters: value the boolean value, true or false

XdmAtomicValue

public XdmAtomicValue(long value)
Create an xs:integer atomic value

Parameters: value the xs:integer value, as a long

XdmAtomicValue

public XdmAtomicValue(BigDecimal value)
Create an xs:decimal atomic value

Parameters: value the xs:decimal value, as a BigDecimal

XdmAtomicValue

public XdmAtomicValue(double value)
Create an xs:double atomic value

Parameters: value the xs:double value, as a double

XdmAtomicValue

public XdmAtomicValue(float value)
Create an xs:float atomic value

Parameters: value the xs:float value, as a float

XdmAtomicValue

public XdmAtomicValue(String value)
Create an xs:string atomic value

Parameters: value the xs:string value, as a string

XdmAtomicValue

public XdmAtomicValue(URI value)
Create an xs:anyURI atomic value

Parameters: value the xs:anyURI value, as a URI

XdmAtomicValue

public XdmAtomicValue(QName value)
Create an xs:QName atomic value

Parameters: value the xs:QName value, as a QName

XdmAtomicValue

public XdmAtomicValue(String lexicalForm, ItemType type)
Construct an atomic value given its lexical representation and the name of the required built-in atomic type.

This method cannot be used to construct values that are namespace-sensitive (QNames and Notations)

Parameters: lexicalForm the value in the lexical space of the target data type. More strictly, the input value before the actions of the whitespace facet for the target data type are applied. type the required atomic type. This must either be one of the built-in atomic types defined in XML Schema, or a user-defined type whose definition appears in a schema that is known to the Processor. It must not be an abstract type.

Throws: SaxonApiException if the type is unknown, or is not atomic, or is namespace-sensitive; or if the value supplied in lexicalForm is not in the lexical space of the specified atomic type.

Method Detail

getBooleanValue

public boolean getBooleanValue()
Get the value converted to a boolean using the XPath casting rules

Returns: the result of converting to a boolean (Note: this is not the same as the effective boolean value).

Throws: SaxonApiException if the value cannot be cast to a boolean

getDecimalValue

public BigDecimal getDecimalValue()
Get the value converted to a decimal using the XPath casting rules

Returns: the result of converting to a decimal

Throws: SaxonApiException if the value cannot be cast to a double

getDoubleValue

public double getDoubleValue()
Get the value converted to a double using the XPath casting rules

Returns: the result of converting to a double

Throws: SaxonApiException if the value cannot be cast to a double

getLongValue

public long getLongValue()
Get the value converted to an integer using the XPath casting rules

Returns: the result of converting to an integer

Throws: SaxonApiException if the value cannot be cast to an integer

getPrimitiveTypeName

public QName getPrimitiveTypeName()
Get the primitive type of this atomic value, as a QName. The primitive types for this purpose are the 19 primitive types of XML Schema, plus xs:integer, xs:dayTimeDuration and xs:yearMonthDuration, and xs:untypedAtomic. For external objects, the result is xs:anyAtomicType.

Returns: a QName naming the primitive type of this atomic value. This will always be an atomic type.

getValue

Object getValue()
Get the value as a Java object of the nearest equivalent type.

The result type is as follows:

XPath type Java class
xs:string String
xs:integer java.math.BigInteger
xs:decimal java.math.BigDecimal
xs:double Double
xs:float Float
xs:boolean Boolean
xs:QName QName
xs:anyURI String
xs:untypedAtomicString
Other types currently String, but this may change in the future

Returns: the value, converted to a Java object of a suitable type

toString

public String toString()
Get the result of converting the atomic value to a string. This has the same effect as the XPath string() function.
