Method Detail

handleAny

void handleAny(Object value)
               throws XMLStreamException

Handle an <xs:any>-type nested element, passing in the given value, returning after the end of the element. Must be positioned on a START_ELEMENT or an exception will occur. On return the cursor will be positioned on the corresponding END_ELEMENT.

Parameters:

value - the value to pass in

Throws:

XMLStreamException - if an error occurs (e.g. the given value does not match the type of the handler for the element, or the element is unknown)

handleAttribute

void handleAttribute(Object value,
                   int index)
                     throws XMLStreamException

Handle an extended attribute, passing in the given value. Must be positioned on a START_ELEMENT or an exception will occur. On return the cursor will be pointing at the same START_ELEMENT.

Parameters:

value - the value to pass in

index - the index of the attribute to process

Throws:

XMLStreamException - if an error occurs

discardRemainder

void discardRemainder()
                      throws XMLStreamException

Discard the remaining content of an element. Runs until a END_ELEMENT is encountered. If a START_ELEMENT is encountered, then recursively consume and ignore its content as well.

Throws:

XMLStreamException - if an error occurs.

getIntAttributeValue

int getIntAttributeValue(int index)
                         throws XMLStreamException

Get the value of an attribute as an integer.

Parameters:

index - the index of the attribute

Returns:

the integer value

Throws:

XMLStreamException - if an error occurs

getIntListAttributeValue

int[] getIntListAttributeValue(int index)
                               throws XMLStreamException

Get the value of an attribute as an integer list.

Parameters:

index - the index of the attribute

Returns:

the integer values

Throws:

XMLStreamException - if an error occurs

getListAttributeValue

List<String> getListAttributeValue(int index)
                                   throws XMLStreamException

Get the value of an attribute as a space-delimited string list.

Parameters:

index - the index of the attribute

Returns:

the values

Throws:

XMLStreamException - if an error occurs

getLongAttributeValue

long getLongAttributeValue(int index)
                           throws XMLStreamException

Get the value of an attribute as a long.

Parameters:

index - the index of the attribute

Returns:

the long value

Throws:

XMLStreamException - if an error occurs

getLongListAttributeValue

long[] getLongListAttributeValue(int index)
                                 throws XMLStreamException

Get the value of an attribute as a long integer list.

Parameters:

index - the index of the attribute

Returns:

the long values

Throws:

XMLStreamException - if an error occurs

getAttributeValue

<T> T getAttributeValue(int index,
                      Class<T> kind)
                    throws XMLStreamException

Get the attribute value using intelligent type conversion. Numeric types will be parsed; enum types will be mapped.

Type Parameters:

T - the type of the expected object

Parameters:

index - the index of the attribute

kind - the class of the expected object

Returns:

the object equivalent

Throws:

XMLStreamException - if an error occurs

getListAttributeValue

<T> List<? extends T> getListAttributeValue(int index,
                                          Class<T> kind)
                                        throws XMLStreamException

Get the attribute value as a list using intelligent type conversion. Numeric types will be parsed; enum types will be mapped.

Parameters:

index - the index of the attribute

kind - the class of the expected object

Returns:

the list of object equivalents

Throws:

XMLStreamException - if an error occurs

getId

String getId()
             throws XMLStreamException

Get the XML ID attribute, if any.

Returns:

the attribute value

Throws:

XMLStreamException - if an error occurs

getXMLMapper

XMLMapper getXMLMapper()

Gets the XMLMapper used to handle extended attributes and xs:any-type nested elements.

Returns:

the XMLMapper. Will not return null

setTrimElementText

void setTrimElementText(boolean trim)

Whether or not XMLStreamReader.getElementText() should trim content. The default is true.

Parameters:
