Enclosing class:

SaxWriterImpl

private static class SaxWriterImpl.FileOutputStreamWrapper
extends java.io.OutputStream

Special wrapper to wrap write to file in lazy mode. It's means that first try to write will check if file is available.

Constructor Detail

FileOutputStreamWrapper

private FileOutputStreamWrapper(java.lang.String source)

Constructor accepting a file name, which will read after first call.

Parameters:

source - A file name.

Method Detail

write

public void write(int b)
           throws java.io.IOException

Write one byte into the stream.

Specified by:

write in class java.io.OutputStream

Parameters:

b - the data to write.

Throws:

java.io.IOException

write

public void write(byte[] b)
           throws java.io.IOException,
                  java.lang.NullPointerException

Writes the entire contents of the specified byte array to this output stream.

Overrides:

write in class java.io.OutputStream

Parameters:

b - The byte array to write.

Throws:

java.io.IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

java.lang.NullPointerException - if the array is null.

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException,
                  java.lang.NullPointerException,
                  java.lang.IndexOutOfBoundsException

Writes len bytes from the specified byte array starting at offset off in this output stream. Element b[off] is the first byte written and b[off+len-1] is the last byte written.

Overrides:

write in class java.io.OutputStream

Parameters:

b - The array of bytes to write.

off - the start offset in the array.

len - the number of bytes to write.

Throws:

java.io.IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

java.lang.NullPointerException - if the array is null.

java.lang.IndexOutOfBoundsException - if the offset or length are negative, or if offset + length is larger than the length of the array.

close

public void close()
           throws java.io.IOException

Close current stream and reset state.

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException

init

private void init(boolean canWrite)
           throws java.io.IOException

Initialization method which creates stream wrapper.

Parameters:

canWrite - if true than file will open in read/write mode, otherwise only in read mode.

Throws:

java.io.IOException - In case of I/O errors.
