Method Detail

doAddEventAttribute

protected void doAddEventAttribute(Attribute attr,
                                   XMLEventParserContext ctx,
                                   XMLEvent event,
                                   Object... args)
                            throws XMLStreamException

Overrides:

doAddEventAttribute in class AbstractXMLEventParser

Throws:

XMLStreamException

getCount

public int getCount()

Indicates the number of elements that this accessor can read. An element is a tuple whose length depends on the number of accessor parameters. For example, if the accessor has three float parameters, than an element is three floats, and this method returns the number of float triplets.

Returns:

Number of elements that the accessor can read.

getFloats

public float[] getFloats()

Copies this accessor's content to a buffer. This method begins writing data at the buffer's current position, and continues until the accessor is out of data.

Returns:

Array of floats. May return null if the data source is not available.

getOffset

public int getOffset()

Indicates the offset into the source data at which the accessor starts reading. Returns zero if this attribute has not been set.

Returns:

Offset at which the accessor starts reading.

getSource

public String getSource()

Get the identifier of this accessor's source.

Returns:

Accessor source.

getStride

public int getStride()

Indicates the number of tokens in the source data to advance between elements.

Returns:

Offset at which the accessor starts reading.

setField

public void setField(String keyName,
                     Object value)

Overrides:

setField in class AbstractXMLEventParser

size

public int size()

Indicates the number of tokens that the accessor can read. For example, if the accessor reads floats, then this method returns the number of floats that the accessor can read.

Returns:

Number of tokens that the accessor can read.
