Method Detail

init

void init()
          throws IOException

Initialize reader.

Throws:

IOException

buildPositionString

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

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:

IllegalStateException - if not at a start or end tag (optional)

getNamespace

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:

IllegalStateException - if not at a start or end tag (optional)

getPrefix

String getPrefix()

Get element prefix from the current start or end tag.

Returns:

prefix text (null if no prefix)

Throws:

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:

IllegalStateException - if not at a start tag (optional)

getAttributeName

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:

IllegalStateException - if not at a start tag or invalid index

getAttributeNamespace

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:

IllegalStateException - if not at a start tag or invalid index

getAttributePrefix

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:

IllegalStateException - if not at a start tag or invalid index

getAttributeValue

String getAttributeValue(int index)

Get an attribute value from the current start tag.

Parameters:

index - attribute index

Returns:

value text

Throws:

IllegalStateException - if not at a start tag or invalid index

getAttributeValue

String getAttributeValue(String ns,
                       String name)

Get an attribute value from the current start tag.

Parameters:

ns - namespace URI for expected attribute (may be null or the empty string for the empty namespace)

name - attribute name expected

Returns:

attribute value text, or null if missing

Throws:

IllegalStateException - if not at a start tag

getText

String getText()

Get current text. When positioned on a TEXT event this returns the actual text; for CDSECT it returns the text inside the CDATA section; for COMMENT, DOCDECL, or PROCESSING_INSTRUCTION it returns the text inside the structure.

Returns:

text for current event

getNestingDepth

int getNestingDepth()

Get current element nesting depth. The returned depth always includes the current start or end tag (if positioned on a start or end tag).

Returns:

element nesting depth

getNamespaceCount

int getNamespaceCount(int depth)

Get number of namespace declarations active at depth.

Parameters:

depth - element nesting depth

Returns:

number of namespaces active at depth

Throws:

IllegalArgumentException - if invalid depth

getNamespaceUri

String getNamespaceUri(int index)

Get namespace URI.

Parameters:

index - declaration index

Returns:

namespace URI

Throws:

IllegalArgumentException - if invalid index

getNamespacePrefix

String getNamespacePrefix(int index)

Get namespace prefix.

Parameters:

index - declaration index

Returns:

namespace prefix, null if a default namespace

Throws:

IllegalArgumentException - if invalid index

getDocumentName

String getDocumentName()

Get document name.

Returns:

document name, null if not known

getLineNumber

Returns:

column number from source document, -1 if column number information not available

getNamespace

String getNamespace(String prefix)

Get namespace URI associated with prefix.

Parameters:

prefix - namespace prefix to be matched (null for default namespace)

Returns:

associated URI (null if prefix not defined)

getInputEncoding

String getInputEncoding()

Return the input encoding, if known. This is only valid after parsing of a document has been started.

Returns:

input encoding (null if unknown)

isNamespaceAware

boolean isNamespaceAware()

Return namespace processing flag.

Returns:

namespace processing flag (true if namespaces are processed by reader, false if not)
