Method Summary

Methods

Modifier and Type	Method and Description
static LinkedBuffer	writeAscii(java.lang.String str, WriteSession session, LinkedBuffer lb) Writes the ascii bytes from the string into the LinkedBuffer.
static LinkedBuffer	writeDouble(double value, WriteSession session, LinkedBuffer lb) Writes the stringified double into the LinkedBuffer.
static LinkedBuffer	writeFloat(float value, WriteSession session, LinkedBuffer lb) Writes the stringified float into the LinkedBuffer.
static LinkedBuffer	writeInt(int value, WriteSession session, LinkedBuffer lb) Writes the stringified int into the LinkedBuffer.
static LinkedBuffer	writeLong(long value, WriteSession session, LinkedBuffer lb) Writes the stringified long into the LinkedBuffer.
static LinkedBuffer	writeUTF8(java.lang.String str, WriteSession session, LinkedBuffer lb) Writes the utf8-encoded bytes from the string into the LinkedBuffer.
static LinkedBuffer	writeUTF8FixedDelimited(java.lang.String str, boolean littleEndian, WriteSession session, LinkedBuffer lb) The length of the utf8 bytes is written first before the string - which is fixed 2-bytes.
static LinkedBuffer	writeUTF8FixedDelimited(java.lang.String str, WriteSession session, LinkedBuffer lb) The length of the utf8 bytes is written first (big endian) before the string - which is fixed 2-bytes.
static LinkedBuffer	writeUTF8VarDelimited(java.lang.String str, WriteSession session, LinkedBuffer lb) The length of the utf8 bytes is written first before the string - which is a variable int (1 to 5 bytes).

Method Detail

writeInt

public static LinkedBuffer writeInt(int value,
                    WriteSession session,
                    LinkedBuffer lb)
                             throws java.io.IOException

Writes the stringified int into the LinkedBuffer.

Throws:

java.io.IOException

writeLong

public static LinkedBuffer writeLong(long value,
                     WriteSession session,
                     LinkedBuffer lb)
                              throws java.io.IOException

Writes the stringified long into the LinkedBuffer.

Throws:

java.io.IOException

writeFloat

public static LinkedBuffer writeFloat(float value,
                      WriteSession session,
                      LinkedBuffer lb)
                               throws java.io.IOException

Writes the stringified float into the LinkedBuffer. TODO - skip string conversion and write directly to buffer

Throws:

java.io.IOException

writeDouble

public static LinkedBuffer writeDouble(double value,
                       WriteSession session,
                       LinkedBuffer lb)
                                throws java.io.IOException

Writes the stringified double into the LinkedBuffer. TODO - skip string conversion and write directly to buffer

Throws:

java.io.IOException

writeUTF8

public static LinkedBuffer writeUTF8(java.lang.String str,
                     WriteSession session,
                     LinkedBuffer lb)
                              throws java.io.IOException

Writes the utf8-encoded bytes from the string into the LinkedBuffer.

Throws:

java.io.IOException

writeAscii

public static LinkedBuffer writeAscii(java.lang.String str,
                      WriteSession session,
                      LinkedBuffer lb)
                               throws java.io.IOException

Writes the ascii bytes from the string into the LinkedBuffer. It is the responsibility of the caller to know in advance that the string is 100% ascii. E.g if you convert a double/float to a string, you are sure it only contains ascii chars.

Throws:

java.io.IOException

writeUTF8FixedDelimited

public static LinkedBuffer writeUTF8FixedDelimited(java.lang.String str,
                                   WriteSession session,
                                   LinkedBuffer lb)
                                            throws java.io.IOException

The length of the utf8 bytes is written first (big endian) before the string - which is fixed 2-bytes. Same behavior as DataOutputStream.writeUTF(String).

Throws:

java.io.IOException

writeUTF8FixedDelimited

public static LinkedBuffer writeUTF8FixedDelimited(java.lang.String str,
                                   boolean littleEndian,
                                   WriteSession session,
                                   LinkedBuffer lb)
                                            throws java.io.IOException

The length of the utf8 bytes is written first before the string - which is fixed 2-bytes.

Throws:

java.io.IOException

writeUTF8VarDelimited

public static LinkedBuffer writeUTF8VarDelimited(java.lang.String str,
                                 WriteSession session,
                                 LinkedBuffer lb)
                                          throws java.io.IOException

The length of the utf8 bytes is written first before the string - which is a variable int (1 to 5 bytes).

Throws:

java.io.IOException
