Method Detail

content

public ByteBuf content()

Description copied from interface: ByteBufHolder

Return the data which is held by this ByteBufHolder.

Specified by:

content in interface ByteBufHolder

copy

public DnsRawRecord copy()

Description copied from interface: ByteBufHolder

Creates a deep copy of this ByteBufHolder.

Specified by:

copy in interface ByteBufHolder

Specified by:

copy in interface DnsRawRecord

duplicate

public DnsRawRecord duplicate()

Description copied from interface: ByteBufHolder

Duplicates this ByteBufHolder. Be aware that this will not automatically call ByteBufHolder.retain().

Specified by:

duplicate in interface ByteBufHolder

Specified by:

duplicate in interface DnsRawRecord

retainedDuplicate

public DnsRawRecord retainedDuplicate()

Description copied from interface: ByteBufHolder

Duplicates this ByteBufHolder. This method returns a retained duplicate unlike ByteBufHolder.duplicate().

Specified by:

retainedDuplicate in interface ByteBufHolder

Specified by:

retainedDuplicate in interface DnsRawRecord

ByteBuf.retainedDuplicate()

replace

public DnsRawRecord replace(ByteBuf content)

Description copied from interface: ByteBufHolder

Returns a new ByteBufHolder which contains the specified content.

Specified by:

replace in interface ByteBufHolder

Specified by:

replace in interface DnsRawRecord

refCnt

public int refCnt()

Description copied from interface: ReferenceCounted

Returns the reference count of this object. If 0, it means this object has been deallocated.

Specified by:

refCnt in interface ReferenceCounted

retain

public DnsRawRecord retain()

Description copied from interface: ReferenceCounted

Increases the reference count by 1.

Specified by:

retain in interface ByteBufHolder

Specified by:

retain in interface DnsRawRecord

Specified by:

retain in interface ReferenceCounted

retain

public DnsRawRecord retain(int increment)

Description copied from interface: ReferenceCounted

Increases the reference count by the specified increment.

Specified by:

retain in interface ByteBufHolder

Specified by:

retain in interface DnsRawRecord

Specified by:

retain in interface ReferenceCounted

release

public boolean release()

Description copied from interface: ReferenceCounted

Decreases the reference count by 1 and deallocates this object if the reference count reaches at 0.

Specified by:

release in interface ReferenceCounted

Returns:

true if and only if the reference count became 0 and this object has been deallocated

release

public boolean release(int decrement)

Description copied from interface: ReferenceCounted

Decreases the reference count by the specified decrement and deallocates this object if the reference count reaches at 0.

Specified by:

release in interface ReferenceCounted

Returns:

true if and only if the reference count became 0 and this object has been deallocated

touch

public DnsRawRecord touch()

Description copied from interface: ReferenceCounted
