BufferManager
public BufferManager()
getBufferManager
public static BufferManager getBufferManager(org.apache.xerces.xni.parser.XMLInputSource inputSource)
throws java.io.IOException
- Throws:
java.io.IOException
getMore
public abstract boolean getMore()
throws java.io.IOException
- This function returns true if some character data was loaded. Data is available via getCharBuffer().
If before calling this function CharBuffer had some data (i.e. remaining() > 0) then this function
first calls CharBuffer.compact() and then it is filled with more data. After calling this function
CharBuffer.position() is always 'zero'.
- Returns:
- true if some character data was loaded. False value can be assume to be end of current
entity.
- Throws:
java.io.IOException
- See Also:

public abstract java.nio.CharBuffer getCharBuffer()
arrangeCapacity
public abstract boolean arrangeCapacity(int length)
throws java.io.IOException
- xxx: This should be an abstract method because in StreamBufferManager
CharBuffer capacity doesn't grow
- Throws:
java.io.IOException
endOfStream
public boolean endOfStream()
- This file signals the end of file
- Returns:
- true/false signals the end of file.
close
public abstract void close()
throws java.io.IOException
- Throws:
java.io.IOException
setEncoding
public abstract void setEncoding(java.lang.String encoding)
throws java.io.IOException
- Throws:
java.io.IOException
getEncodingName
protected java.lang.Object[] getEncodingName(byte[] b4,
int count)
- Returns the IANA encoding name that is auto-detected from
the bytes specified, with the endian-ness of that encoding where appropriate.
- Parameters:
b4
- The first four bytes of the input.count
- The number of bytes actually read.
- Returns:
- a 2-element array: the first element, an IANA-encoding string,
the second element a Boolean which is true iff the document is big endian, false
if it's little-endian, and null if the distinction isn't relevant.
