Method Detail

### buildPositionString

    java.lang.String buildPositionString()

  Build current parse input position description.

  Returns:
    text description of current parse position

### nextToken

    int nextToken()
                  throws JiBXException

  Advance to next parse event of input document.

  Returns:
    parse event type code
  Throws:
    `JiBXException` - if error reading or parsing document

### next

    int next()
             throws JiBXException

  Advance to next binding component of input document. This is a higher-level operation than `nextToken()`, which consolidates text content and ignores parse events for components such as comments and PIs.

  Returns:
    parse event type code
  Throws:
    `JiBXException` - if error reading or parsing document

### getEventType

    int getEventType()
                     throws JiBXException

  Gets the current parse event type, without changing the current parse state.

  Returns:
    parse event type code
  Throws:
    `JiBXException` - if error parsing document

### getName

    java.lang.String getName()

  Get element name from the current start or end tag.

  Returns:
    local name if namespace handling enabled, full name if namespace handling disabled
  Throws:
    `java.lang.IllegalStateException` - if not at a start or end tag (optional)

### getNamespace

    java.lang.String getNamespace()

  Get element namespace from the current start or end tag.

  Returns:
    namespace URI if namespace handling enabled and element is in a namespace, empty string otherwise
  Throws:
    `java.lang.IllegalStateException` - if not at a start or end tag (optional)

### getPrefix

    java.lang.String getPrefix()

  Get element prefix from the current start or end tag.

  Returns:
    prefix text (`null` if no prefix)
  Throws:
    `java.lang.IllegalStateException` - if not at a start or end tag

### getAttributeCount

    int getAttributeCount()

  Get the number of attributes of the current start tag.

  Returns:
    number of attributes
  Throws:
    `java.lang.IllegalStateException` - if not at a start tag (optional)

### getAttributeName

    java.lang.String getAttributeName(int index)

  Get an attribute name from the current start tag.

  Parameters:
    `index` - attribute index
  Returns:
    local name if namespace handling enabled, full name if namespace handling disabled
  Throws:
    `java.lang.IllegalStateException` - if not at a start tag or invalid index

### getAttributeNamespace

    java.lang.String getAttributeNamespace(int index)

  Get an attribute namespace from the current start tag.

  Parameters:
    `index` - attribute index
  Returns:
    namespace URI if namespace handling enabled and attribute is in a namespace, empty string otherwise
  Throws:
    `java.lang.IllegalStateException` - if not at a start tag or invalid index

### getAttributePrefix

    java.lang.String getAttributePrefix(int index)

  Get an attribute prefix from the current start tag.

  Parameters:
    `index` - attribute index
  Returns:
    prefix for attribute (`null` if no prefix present)
  Throws:
    `java.lang.IllegalStateException` - if not at a start tag or invalid index

### getAttributeValue

    java.lang.String getAttributeValue(int index)

  Get an attribute value from the current start tag.

  Parameters:
    `index` - attribute index
  Returns:
    value text
  Throws:
    `java.lang.IllegalStateException` - if not at a start tag or invalid index

### getAttributeValue

    java.lang.String getAttributeValue(java.lang.String ns,
                                       java.lang.String name)

  Get an attribute value from the current start tag.

### getText
