SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
Interface for reading variable byte encoded values. Variable byte encoding offers a good compression ratio if the stored values are rather small, i.e. much smaller than the possible maximum for the given type.
Method Summary | |
int |
available()
Returns a value > 0 if more bytes can be read from the input. |
void |
copyRaw(VariableByteOutputStream os,
int bytes)
|
void |
copyTo(VariableByteOutputStream os)
Copy the next numeric value from the input to the specified output stream. |
void |
copyTo(VariableByteOutputStream os,
int count)
Copy the count next numeric values from the input to the specified output stream. |
int |
read()
Read a single byte and return as an int value. |
int |
read(byte[] data)
Fill the provided byte array with data from the input. |
int |
read(byte[] b,
int off,
int len)
|
byte |
readByte()
Read a single byte. |
int |
readFixedInt()
|
int |
readInt()
Read an integer value in variable byte encoding. |
long |
readLong()
Read a long value in variable byte encoding. |
short |
readShort()
Read a short value in variable byte encoding. |
java.lang.String |
readUTF()
|
void |
skip(int count)
Read the following count numeric values from the input and drop them. |
void |
skipBytes(long count)
