Method Detail

init

void init(IValueReader valueReader,
          DataType keyType,
          IPoolFactory<?> factory)

setLoadDone

void setLoadDone()
          throws InvalidJfrFileException

Throws:

InvalidJfrFileException

touchAll

void touchAll()

readValue

void readValue(byte[] data,
               Offset offset,
               long timestamp)
        throws InvalidJfrFileException

Throws:

InvalidJfrFileException

put

private void put(long valueId,
                 java.lang.Object value,
                 long timestamp)

getContentType

ContentType<?> getContentType()

get

java.lang.Object get(long valueId,
                     long atTimestamp)

Returns one of the values identified by valueId. The value returned is the value associated with the smallest timestamp larger than or equals to atTimestamp. If the map doesn't contain a value identified by valueId, a dummy object may be returned.

getEntryList

private ConstantEntryList getEntryList(long valueId)

resolve

static java.lang.Object resolve(java.lang.Object o,
                                long atTimestamp)
