Method Detail

pullNextEvent

protected int pullNextEvent()

Description copied from class: AbstractPullReader

Pull the next event from the stream.

This MUST return AbstractPullReader.START_NODE, AbstractPullReader.END_NODE, AbstractPullReader.TEXT, AbstractPullReader.COMMENT, AbstractPullReader.OTHER or throw StreamException.

The underlying pull parser will most likely return its own event types. These must be mapped to the appropriate events.

Specified by:

pullNextEvent in class AbstractPullReader

pullElementName

protected java.lang.String pullElementName()

Description copied from class: AbstractPullReader

Pull the name of the current element from the stream.

Specified by:

pullElementName in class AbstractPullReader

pullText

protected java.lang.String pullText()

Description copied from class: AbstractPullReader

Pull the contents of the current text node from the stream.

Specified by:

pullText in class AbstractPullReader

getAttribute

public java.lang.String getAttribute(java.lang.String name)

Description copied from interface: HierarchicalStreamReader

Get the value of an attribute of the current node.

If no such attribute exists, the method returns null.

getAttribute

public java.lang.String getAttribute(int index)

Description copied from interface: HierarchicalStreamReader

Get the value of an attribute of the current node, by index.

Note, the behavior of this method is dependent on the underlying parser when calling it with a non-existing index. Typically some kind of RuntimeException is thrown.

getAttributeCount

public int getAttributeCount()

Description copied from interface: HierarchicalStreamReader

Number of attributes in current node.

getAttributeName

public java.lang.String getAttributeName(int index)

Description copied from interface: HierarchicalStreamReader

Name of attribute in current node.

Note, the behavior of this method is dependent on the underlying parser when calling it with a non-existing index. Typically some kind of RuntimeException is thrown.

appendErrors

public void appendErrors(ErrorWriter errorWriter)

Description copied from interface: ErrorReporter

Append context information to an ErrorWriter.

Parameters:

errorWriter - the error writer

close

public void close()

Description copied from interface: HierarchicalStreamReader

Close the reader, if necessary.
