PacketDecoderImpl

public PacketDecoderImpl(byte[] bytes,
                         int parsePosition)

Method Detail

getBytes

public byte[] getBytes()

setBytes

public void setBytes(byte[] bytes)

getParsePosition

public int getParsePosition()

Description copied from interface: PacketDecoder

Get the current parse position of this packet decoder.

Specified by:

getParsePosition in interface PacketDecoder

Returns:

The current parse position.

setParsePosition

public void setParsePosition(int pos)

Description copied from interface: PacketDecoder

Set the current parse position of this decoder.

Specified by:

setParsePosition in interface PacketDecoder

Parameters:

pos - The new parse position.

getAvailableBytes

public int getAvailableBytes()

Description copied from interface: PacketDecoder

Get the number of available bytes to be read by this decoder.

Specified by:

getAvailableBytes in interface PacketDecoder

Returns:

The number of bytes that can be decoded.

readByte

public byte readByte()

Description copied from interface: PacketDecoder

Read a byte from the byte array.

Specified by:

readByte in interface PacketDecoder

Returns:

The byte at the specified parse position in the array.

readCString

public String readCString()

Description copied from interface: PacketDecoder

Read a C-String (a string terminated by a nul-byte) from the byte array. The bytes will be interpreted as US-ASCII characters.

Specified by:

readCString in interface PacketDecoder

Returns:

The decoded String.

readString

public String readString(int length)

Description copied from interface: PacketDecoder

Read a fixed-length String from the bytes. The bytes will be interpreted as US-ASCII characters.

Specified by:

readString in interface PacketDecoder

Parameters:

length - The number of bytes to parse for the string.

Returns:

The decoded String.

readUInt1

public int readUInt1()

Description copied from interface: PacketDecoder

Read a 1-byte unsigned integer from the array.

Specified by:

readUInt1 in interface PacketDecoder

Returns:

The decoded integer.

readUInt2

public int readUInt2()

Description copied from interface: PacketDecoder

Read a 2-byte unsigned integer from the array. SMPP integers are big-endian, also known as network byte order.

Specified by:

readUInt2 in interface PacketDecoder

Returns:

The decoded integer.

readUInt4

public long readUInt4()

Description copied from interface: PacketDecoder

Read a 4-byte unsigned integer from the array. SMPP integers are big-endian, also known as network byte order. Since the integers are unsigned, a Java long primitive is required to hold all the possible values.

Specified by:

readUInt4 in interface PacketDecoder

Returns:

The decoded (long) integer.

readInt8

public long readInt8()

Specified by:

readInt8 in interface PacketDecoder

readAddress

public Address readAddress()

Description copied from interface: PacketDecoder

Read an SMPP address from the byte array.

Specified by:

readAddress in interface PacketDecoder

Returns:

The parsed address.

readErrorAddress

public ErrorAddress readErrorAddress()

Description copied from interface: PacketDecoder

Read an SMPP address and error code pairing. This is used in the submit multi response packet to create its table of unsuccessful submissions.

Specified by:

readErrorAddress in interface PacketDecoder

Returns:

An error address object.

readDate

public SMPPDate readDate()

Description copied from interface: PacketDecoder

Read an SMPP date from the byte array.

Specified by:

readDate in interface PacketDecoder

Returns:

The parsed SMPP date, or null if the date is null.

readBytes

public byte[] readBytes(int length)

Description copied from interface: PacketDecoder

Get a byte array sub-set from the specified byte array.

Specified by:

readBytes in interface PacketDecoder

Parameters:

length - The number of bytes to copy out of the array.

Returns:

A byte array with length bytes in it copied from bytes.
