Class TypedString

java.lang.Object
  weblogic.wtc.jatmi.StandardTypes
      weblogic.wtc.jatmi.TypedString

All Implemented Interfaces:

Serializable, TypedBuffer

public final class TypedString
extends StandardTypes
implements TypedBuffer, Serializable

This is the jatmi analogue to the STRING Tuxedo buffer type

StandardTypes, TypedBuffer, Serialized Form

TypedString

public TypedString()

Generates a StringBuffer with the default capacity of 16

TypedString

public TypedString(int capacity)

Creates an empty StringBuffer that has the initial capacity given

Parameters:

capacity - The capacity the StringBuffer associated with this TypedString should have

TypedString

public TypedString(String str)

Constructor. Initializes object with a copy of the input string

Parameters:

str - the string to initialize this object with

getStringBuffer

public StringBuffer getStringBuffer()

Gets the StringBuffer associated with this object. Note that the object returned is the same object store used by this object, so care should be taken when updating the object returned while this TypedString is used in another thread. Use the toString method on this object to return this object as a String.

Returns:

The StringBuffer associated with this TypedString

_tmpresend

public void _tmpresend(DataOutputStream encoder)
                throws TPException,
                       IOException

This function presends and encodes the given TypedBuffer object. It is equivalent to the combination of _tmpresend and _tmencdec functions from the buffer(3i) TUXEDO manual page.

XDR encodes the given string. XDR encoding of a string is four length bytes (not including any NULL byte at the end) followed by the string itself (low 32 bits of the unicode characters). It is padded out to make the total length a multiple of four.

Specified by:

_tmpresend in interface TypedBuffer

Parameters:

encoder - The output stream to encode this type to. Should not be padded.

Throws:

TPException -

• TPEINVAL - If there was some problem with the state of the TypedBuffer.
• Any other errno is considered a fatal error

IOException - If there was an error writing to the DataOutputStream

_tmpostrecv

public void _tmpostrecv(DataInputStream decoder,
                        int recv_size)
                 throws TPException,
                        IOException

XDR decodes the given string. XDR encoding of a string is four length bytes (not including any NULL byte at the end) followed by the string itself (low 32 bits of the unicode characters). It is padded out to make the total length a multiple of four.

Specified by:

_tmpostrecv in interface TypedBuffer

Parameters:

decoder - A stream that starts with the encoded data for this buffer type. Only recv_size bytes should be read from the stream (though at the time this function is called all bytes necessary to decode this type should be available)

recv_size - The total size of encoded data from the start position (note that encoded may be larger than the actual recieved size)

Throws:

TPException - TPEINVAL if this stream could not be decoded for any reason

IOException - if there was an error reading from the stream

toString

public String toString()

Returns a copy of this object as a String

Overrides:

toString in class Object
