| IndexOutput | | abstract public class IndexOutput (Code) | | Abstract base class for output to a file in a Directory. A random-access
output stream. Used for all Lucene index output operations.
See Also: Directory
See Also: IndexInput |
| Method Summary | |
| abstract public void | close()
Closes this stream to further operations. | | public void | copyBytes(IndexInput input, long numBytes)
Copy numBytes bytes from input to ourself. | | abstract public void | flush()
Forces any buffered output to be written. | | abstract public long | getFilePointer()
Returns the current position in this file, where the next write will
occur. | | abstract public long | length()
The number of bytes in the file. | | abstract public void | seek(long pos)
Sets current position in this file, where the next write will occur. | | abstract public void | writeByte(byte b)
Writes a single byte. | | public void | writeBytes(byte[] b, int length)
Writes an array of bytes. | | abstract public void | writeBytes(byte[] b, int offset, int length)
Writes an array of bytes. | | public void | writeChars(String s, int start, int length)
Writes a sequence of UTF-8 encoded characters from a string. | | public void | writeChars(char[] s, int start, int length)
Writes a sequence of UTF-8 encoded characters from a char[]. | | public void | writeInt(int i)
Writes an int as four bytes. | | public void | writeLong(long i)
Writes a long as eight bytes. | | public void | writeString(String s)
Writes a string. | | public void | writeVInt(int i)
Writes an int in a variable-length format. | | public void | writeVLong(long i)
Writes an long in a variable-length format. |
| close | | abstract public void close() throws IOException(Code) | | Closes this stream to further operations.
|
| flush | | abstract public void flush() throws IOException(Code) | | Forces any buffered output to be written.
|
| getFilePointer | | abstract public long getFilePointer()(Code) | | Returns the current position in this file, where the next write will
occur.
See Also: IndexOutput.seek(long) |
| length | | abstract public long length() throws IOException(Code) | | The number of bytes in the file.
|
| writeBytes | | abstract public void writeBytes(byte[] b, int offset, int length) throws IOException(Code) | | Writes an array of bytes.
Parameters:
b - the bytes to write
Parameters:
offset - the offset in the byte array
Parameters:
length - the number of bytes to write
See Also: IndexInput.readBytes(byte[]intint) |
| writeChars | | public void writeChars(String s, int start, int length) throws IOException(Code) | | Writes a sequence of UTF-8 encoded characters from a string.
Parameters:
s - the source of the characters
Parameters:
start - the first character in the sequence
Parameters:
length - the number of characters in the sequence
See Also: IndexInput.readChars(char[]intint) |
| writeChars | | public void writeChars(char[] s, int start, int length) throws IOException(Code) | | Writes a sequence of UTF-8 encoded characters from a char[].
Parameters:
s - the source of the characters
Parameters:
start - the first character in the sequence
Parameters:
length - the number of characters in the sequence

| writeVInt | | public void writeVInt(int i) throws IOException(Code) | | Writes an int in a variable-length format. Writes between one and
five bytes. Smaller values take fewer bytes. Negative numbers are not
supported.
See Also: IndexInput.readVInt |
| writeVLong | | public void writeVLong(long i) throws IOException(Code) | | Writes an long in a variable-length format. Writes between one and five
bytes. Smaller values take fewer bytes. Negative numbers are not
supported.
