Methods Summary
public abstract void	close() Closes this stream to further operations.
public abstract void	flush() Forces any buffered output to be written.
public abstract long	getFilePointer() Returns the current position in this file, where the next write will occur. see #seek(long)
public abstract long	length() The number of bytes in the file.
public abstract void	seek(long pos) Sets current position in this file, where the next write will occur. see #getFilePointer()
public abstract void	writeByte(byte b) Writes a single byte. see IndexInput#readByte()
public abstract void	writeBytes(byte[] b, int length) Writes an array of bytes. param b the bytes to write param length the number of bytes to write see IndexInput#readBytes(byte[],int,int)
public void	writeChars(java.lang.String s, int start, int length) Writes a sequence of UTF-8 encoded characters from a string. param s the source of the characters param start the first character in the sequence param length the number of characters in the sequence see IndexInput#readChars(char[],int,int) final int end = start + length; for (int i = start; i < end; i++) { final int code = (int)s.charAt(i); if (code >= 0x01 && code <= 0x7F) writeByte((byte)code); else if (((code >= 0x80) && (code <= 0x7FF)) || code == 0) { writeByte((byte)(0xC0 | (code >> 6))); writeByte((byte)(0x80 | (code & 0x3F))); } else { writeByte((byte)(0xE0 | (code >>> 12))); writeByte((byte)(0x80 | ((code >> 6) & 0x3F))); writeByte((byte)(0x80 | (code & 0x3F))); } }
public void	writeInt(int i) Writes an int as four bytes. see IndexInput#readInt() writeByte((byte)(i >> 24)); writeByte((byte)(i >> 16)); writeByte((byte)(i >> 8)); writeByte((byte) i);
public void	writeLong(long i) Writes a long as eight bytes. see IndexInput#readLong() writeInt((int) (i >> 32)); writeInt((int) i);
public void	writeString(java.lang.String s) Writes a string. see IndexInput#readString() int length = s.length(); writeVInt(length); writeChars(s, 0, length);
public void	writeVInt(int i) 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 IndexInput#readVInt() while ((i & ~0x7F) != 0) { writeByte((byte)((i & 0x7f) | 0x80)); i >>>= 7; } writeByte((byte)i);
public void	writeVLong(long i) Writes an long in a variable-length format. Writes between one and five bytes. Smaller values take fewer bytes. Negative numbers are not supported. see IndexInput#readVLong() while ((i & ~0x7F) != 0) { writeByte((byte)((i & 0x7f) | 0x80)); i >>>= 7; } writeByte((byte)i);
