Constructor Detail

UnicodeFormat

public UnicodeFormat(int opt)

Create a object to format network data using Unicode.

Parameters:

opt - client server role iptions

Method Detail

isNative

public boolean isNative()

Description copied from class: NativeFormat

Gets format, convenience method.

Overrides:

isNative in class NativeFormat

Returns:

false.

See Also:

NativeFormat.getFormat(), NativeFormat.isUTF8(), NativeFormat.isUnicode()

isUnicode

public boolean isUnicode()

Description copied from class: NativeFormat

Gets format, convenience method.

Overrides:

isUnicode in class NativeFormat

Returns:

false.

See Also:

NativeFormat.getFormat(), NativeFormat.isNative(), NativeFormat.isUTF8()

isUTF8

public boolean isUTF8()

Description copied from class: NativeFormat

Gets format, convenience method.

Overrides:

isUTF8 in class NativeFormat

Returns:

true.

See Also:

NativeFormat.getFormat(), NativeFormat.isNative(), NativeFormat.isUnicode()

getBytes

public byte[] getBytes(java.lang.String str,
                       int len)
                throws java.io.UnsupportedEncodingException,
                       DataTruncationException

Converts a string into a fixed length array of bytes. This is intended for sending data in "network" format, and interpets the length in characters instead of bytes.

Overrides:

getBytes in class NativeFormat

Parameters:

str - String to convert

len - the requested length is doubled

Returns:

the converted byte array

Throws:

java.io.UnsupportedEncodingException - not likely

DataTruncationException - if the result is truncated

getDataInput

public NativeDataInputStream getDataInput(TraceBufferInputStream in)

Creates an input filter stream to read network data.

Overrides:

getDataInput in class NativeFormat

Parameters:

in - underlying input stream

Returns:

a native data input stream

See Also:

NativeDataInputStream

getDataOutput

public NativeDataOutputStream getDataOutput(TraceBufferOutputStream out)

Creates an output filter stream to writes network data.

Overrides:

getDataOutput in class NativeFormat

Parameters:

out - underlying DataOutputStream

Returns:

a native output stream.
