Method Summary

Methods

Modifier and Type	Method and Description
void	endOfInput() Method that should be called after last chunk of data to parse has been fed (with AsyncInputFeeder.feedInput(byte[], int, int)); can be called regardless of what AsyncInputFeeder.needMoreInput() returns.
void	feedInput(byte[] data, int offset, int len) Method that can be called to feed more data, if (and only if) AsyncInputFeeder.needMoreInput() returns true.
AsyncInputFeeder	getInputFeeder() Method used to access AsyncInputFeeder which is used to provide XML content to parse in non-blocking manner (see AsyncInputFeeder for more details).
boolean	needMoreInput() Method called to check whether it is ok to feed more data: parser returns true if it has no more content to parse (and it is ok to feed more); otherwise false (and no data should yet be fed).

Method Detail

getInputFeeder

public AsyncInputFeeder getInputFeeder()

Description copied from interface: AsyncXMLStreamReader

Method used to access AsyncInputFeeder which is used to provide XML content to parse in non-blocking manner (see AsyncInputFeeder for more details).

Specified by:

getInputFeeder in interface AsyncXMLStreamReader

Returns:

Input feeder to use for "pushing" content to parse.

needMoreInput

public boolean needMoreInput()

Description copied from interface: AsyncInputFeeder

Method called to check whether it is ok to feed more data: parser returns true if it has no more content to parse (and it is ok to feed more); otherwise false (and no data should yet be fed).

Specified by:

needMoreInput in interface AsyncInputFeeder

endOfInput

public void endOfInput()

Description copied from interface: AsyncInputFeeder

Method that should be called after last chunk of data to parse has been fed (with AsyncInputFeeder.feedInput(byte[], int, int)); can be called regardless of what AsyncInputFeeder.needMoreInput() returns. After calling this method, no more data can be fed; and parser assumes no more data will be available.

Specified by:

endOfInput in interface AsyncInputFeeder

feedInput

public void feedInput(byte[] data,
             int offset,
             int len)
               throws XMLStreamException

Description copied from interface: AsyncInputFeeder

Method that can be called to feed more data, if (and only if) AsyncInputFeeder.needMoreInput() returns true.

Specified by:

feedInput in interface AsyncInputFeeder

Parameters:

data - Byte array that containts data to feed: caller must ensure data remains stable until it is fully processed (which is true when AsyncInputFeeder.needMoreInput() returns true)

offset - Offset within array where input data to process starts

len - Length of input data within array to process.

Throws:

XMLStreamException - if the state is such that this method should not be called (has not yet consumed existing input data, or has been marked as closed)
