Field Detail

ENCODING

public static final java.lang.String[] ENCODING

These are the encodings used to decode the USB String Descriptors.

For all encodings supported by Java, see:

Java 1 (1.1) Supported Encodings

Java 2 (1.3) Supported Encodings

Java 2 (1.3) Required Encodings

The translation is done using the first available of these encodings:

• UnicodeLittleUnmarked
• UnicodeLittle
• UTF-16LE
• ASCII (after conversion from 16 bit to 8 bit)

ENCODING_8BIT

public static final java.lang.String ENCODING_8BIT

Fallback encoding if no 16-bit encoding is supported

Constructor Detail

UsbStringDescriptorImp

public UsbStringDescriptorImp(byte bLength,
                              byte bDescriptorType,
                              byte[] bString)

Constructor.

Parameters:

bLength - This descriptor's bLength.

bDescriptorType - This descriptor's bDescriptorType.

bString - This descriptor's bString.

Method Detail

bString

public byte[] bString()

Get this descriptor's bString.

Specified by:

bString in interface UsbStringDescriptor

Returns:

This descriptor's bString.

getString

public java.lang.String getString()
                           throws java.io.UnsupportedEncodingException

Get this descriptor's translated String.

This is the String translation of the bString. The best available 16-bit encoding is used. If no 16-bit encoding is available, 8-bit encoding is used, unless any of the characters are 16 bit (high byte is non-zero); then 8-bit encoding is not used, and an UnsupportedEncodingException is thrown.

Specified by:

getString in interface UsbStringDescriptor

Returns:

This descriptor's String.

Throws:

java.io.UnsupportedEncodingException - If no encodings are available.

equals

public boolean equals(java.lang.Object object)

Compare this to an Object.

Overrides:

equals in class UsbDescriptorImp

Parameters:

object - The Object to compare to.

Returns:

If this is equal to the Object.
