| Method Summary | |
| public String | fromBytes(byte[] bytes, int offset, int count)
This method converts a sequence of UTF-32 encoded bytes into
a Java String. | | public String | fromBytes(byte[] bytes)
A convenience method that converts an entire byte array
into a Java String.
Parameters:
bytes - the source byte array. | | public static UTF32 | getBEInstance()
Get an instance that implements UTF-32BE encoding. | | public static UTF32 | getInstance(String encoding)
Get an instance that implements either UTF-32BE or UTF32-LE,
depending on the encoding name suppled.
Parameters:
encoding - the encoding name - must be "UTF-32BE" or "UTF-32LE". | | public static UTF32 | getLEInstance()
Get an instance that implemnts the UTF-32LE encoding. | | abstract protected void | pack(byte[] bytes, int codePoint, int out)
This method packs a 32-bit Unicode code point into the byte array. | | public byte[] | toBytes(String utf16)
Convert a Java String into an array of UTF-32 encoded bytes. | | abstract protected int | unpack(byte[] bytes, int index)
This method unpacks bytes from the encoded byte array into a 32-bit
Unicode code point. |
| fromBytes | | public String fromBytes(byte[] bytes, int offset, int count)(Code) | | This method converts a sequence of UTF-32 encoded bytes into
a Java String. It calls the unpack method to implement
the encoding.
Parameters:
bytes - the source byte array.
Parameters:
offset - the starting offset in the byte array.
Parameters:
count - the number of bytes to process. the Java String. |
| fromBytes | | public String fromBytes(byte[] bytes)(Code) | | A convenience method that converts an entire byte array
into a Java String.
Parameters:
bytes - the source byte array. the Java String. |
| getBEInstance | | public static UTF32 getBEInstance()(Code) | | Get an instance that implements UTF-32BE encoding.
the instance. |
| getInstance | | public static UTF32 getInstance(String encoding)(Code) | | Get an instance that implements either UTF-32BE or UTF32-LE,
depending on the encoding name suppled.
Parameters:
encoding - the encoding name - must be "UTF-32BE" or "UTF-32LE". the instance. |
| getLEInstance | | public static UTF32 getLEInstance()(Code) | | Get an instance that implemnts the UTF-32LE encoding.
the instance. |
| pack | | abstract protected void pack(byte[] bytes, int codePoint, int out)(Code) | | This method packs a 32-bit Unicode code point into the byte array. It is
implemented by subclasses that implement the BE and LE encodings.
Parameters:
bytes - the destination byte array
Parameters:
codePoint - the 32-bit Unicode code point
Parameters:
out - the destination index in bytes. |
| toBytes | | public byte[] toBytes(String utf16)(Code) | | Convert a Java String into an array of UTF-32 encoded bytes. Calls
the pack method to do the encoding.
Parameters:
utf16 - the source Java String. an array of UTF-32 encoded bytes. |
| unpack | | abstract protected int unpack(byte[] bytes, int index)(Code) | | This method unpacks bytes from the encoded byte array into a 32-bit
Unicode code point. It is implmeented by subclasses that implmeent the BE and LE encodings.
Parameters:
bytes - the source byte array.
Parameters:
index - the index of the first source byte. the 32-bit Unicode code point. |
