Constructor Detail

HexBinaryValue

public HexBinaryValue(java.lang.CharSequence in)
               throws XPathException

Constructor: create a hexBinary value from a supplied string, in which each octet is represented by a pair of values from 0-9, a-f, A-F

Throws:

XPathException

HexBinaryValue

public HexBinaryValue(byte[] value)

Constructor: create a hexBinary value from a given array of bytes

Method Detail

getBinaryValue

public byte[] getBinaryValue()

Get the binary value

convertPrimitive

public AtomicValue convertPrimitive(BuiltInAtomicType requiredType,
                                    boolean validate,
                                    XPathContext context)

Convert to target data type

Specified by:

convertPrimitive in class AtomicValue

Parameters:

requiredType - an integer identifying the required atomic type

context -

validate - true if validation is required. If set to false, the caller guarantees that the value is valid for the target data type, and that further validation is therefore not required. Note that a validation failure may be reported even if validation was not requested.

Returns:

an AtomicValue, a value of the required type; or an ErrorValue

getStringValue

public java.lang.String getStringValue()

Convert to string

Specified by:

getStringValue in interface Item

Specified by:

getStringValue in interface ValueRepresentation

Specified by:

getStringValue in class AtomicValue

Returns:

the canonical representation.

See Also:

Item.getStringValueCS()

getItemType

public ItemType getItemType(TypeHierarchy th)

Determine the data type of the exprssion

Specified by:

getItemType in interface Expression

Overrides:

getItemType in class Value

Parameters:

th -

Returns:

Type.HEX_BINARY_TYPE

getLengthInOctets

public int getLengthInOctets()

Get the number of octets in the value

convertToJava

public java.lang.Object convertToJava(java.lang.Class target,
                                      XPathContext context)
                               throws XPathException

Convert to Java object (for passing to external functions)

Overrides:

convertToJava in class Value

Throws:

XPathException

equals

public boolean equals(java.lang.Object other)

Test if the two hexBinary values are equal.

Overrides:

equals in class Value

hashCode

public int hashCode()

Description copied from class: Value

Return a hash code to support the equals() function

Overrides:

hashCode in class Value
