                                            BufferUnderflowException

Converts the bytes from a BytesStore into a UTF-8 encoded string. The bytes are assumed to be in UTF-8 format and are decoded accordingly.

Specified by:

getValue in class AbstractInterner<String>

Parameters:

cs - the BytesStore containing the bytes to be converted

length - the number of bytes to read from the BytesStore

Returns:

the resulting UTF-8 encoded string

Throws:

UTFDataFormatRuntimeException - If the bytes are not valid UTF-8 encoded characters

BufferUnderflowException - If the buffer's limits are exceeded

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
