Method Detail

create

public static LedgerEntryImpl create(long ledgerId,
                                     long entryId)

create

public static LedgerEntryImpl create(long ledgerId,
                                     long entryId,
                                     long length,
                                     io.netty.buffer.ByteBuf buf)

duplicate

public static LedgerEntryImpl duplicate(LedgerEntry entry)

setEntryId

public void setEntryId(long entryId)

setLength

public void setLength(long length)

setEntryBuf

public void setEntryBuf(io.netty.buffer.ByteBuf buf)

getLedgerId

public long getLedgerId()

The id of the ledger which contains the entry.

Specified by:

getLedgerId in interface LedgerEntry

Returns:

the id of the ledger

getEntryId

public long getEntryId()

The id of the entry.

Specified by:

getEntryId in interface LedgerEntry

Returns:

the id of the entry

getLength

public long getLength()

The length of the entry, that is the size of the content expressed in bytes.

Specified by:

getLength in interface LedgerEntry

Returns:

the size of the content

getEntryBytes

public byte[] getEntryBytes()

Returns the content of the entry as a byte array.

Specified by:

getEntryBytes in interface LedgerEntry

Returns:

the content of the entry

getEntryBuffer

public io.netty.buffer.ByteBuf getEntryBuffer()

Return the internal ByteBuf that contains the entry payload.

This call doesn't change the reference count on the returned bytebuf. If you want to use the bytebuf after the entry is released (via LedgerEntry.close(), the caller must retain the references of the bytebuf.

Specified by:

getEntryBuffer in interface LedgerEntry

Returns:

a ByteBuf which contains the data

getEntryNioBuffer

public java.nio.ByteBuffer getEntryNioBuffer()

Exposes this entry's data as an NIO ByteBuffer. The returned buffer shares the content with this underneath bytebuf (which you can get it by LedgerEntry.getEntryBuffer()). Changing the position and limit of the returned NIO buffer does not affect the indexes and marks of this underneath buffer. This method is identical to entry.getEntryBuffer().nioBuffer(). This method does not modify readerIndex or writerIndex of the underlying bytebuf.

Specified by:

getEntryNioBuffer in interface LedgerEntry

duplicate

public LedgerEntryImpl duplicate()

Returns a duplicate of this entry.

This call will retain a slice of the underneath byte buffer.

Specified by:

duplicate in interface LedgerEntry

Returns:

a duplicated ledger entry

close

public void close()

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface LedgerEntry
