Class Bit8StringInterner

java.lang.Object

net.openhft.chronicle.bytes.util.AbstractInterner<String>

net.openhft.chronicle.bytes.util.Bit8StringInterner

public class Bit8StringInterner
extends AbstractInterner<String>

Implementation of AbstractInterner for interning String objects whose bytes are assumed to represent 8-bit characters such as ISO-8859-1.

Example usage:

 Bit8StringInterner interner = new Bit8StringInterner(128);
 String s = interner.intern(bytes, length);

                                            BufferUnderflowException

Decodes an 8-bit character sequence from the provided BytesStore. Exactly length bytes are read starting from cs.readPosition(). The read position is not modified.

Specified by:

getValue in class AbstractInterner<String>

Parameters:

cs - the bytes store containing the characters

length - the number of bytes to read

Returns:

the resulting string

Throws:

BufferUnderflowException - If the BytesStore doesn't have enough remaining capacity

net.openhft.chronicle.core.io.ClosedIllegalStateException - If the resource has been released or closed.

net.openhft.chronicle.core.io.ThreadingIllegalStateException - If this resource was accessed by multiple threads in an unsafe way

IllegalStateException
