Field Detail

NULL_INSTANCE

public static final FullBulkStringRedisMessage NULL_INSTANCE

A predefined null instance of FullBulkStringRedisMessage.

EMPTY_INSTANCE

public static final FullBulkStringRedisMessage EMPTY_INSTANCE

A predefined empty instance of FullBulkStringRedisMessage.

Constructor Detail

FullBulkStringRedisMessage

public FullBulkStringRedisMessage(ByteBuf content)

Creates a FullBulkStringRedisMessage for the given content.

Parameters:

content - the content, must not be null. If content is null or empty, use NULL_INSTANCE or EMPTY_INSTANCE instead of constructor.

Method Detail

isNull

public boolean isNull()

Returns whether the content of this message is null.

Returns:

indicates whether the content of this message is null.

toString

public String toString()

Overrides:

toString in class DefaultByteBufHolder

copy

public FullBulkStringRedisMessage copy()

Description copied from class: DefaultByteBufHolder

Creates a deep copy of this ByteBufHolder.

This method calls replace(content().copy()) by default.

Specified by:

copy in interface ByteBufHolder

Specified by:

copy in interface BulkStringRedisContent

Specified by:

copy in interface LastBulkStringRedisContent

Overrides:

copy in class DefaultByteBufHolder

duplicate

public FullBulkStringRedisMessage duplicate()

Description copied from class: DefaultByteBufHolder

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

This method calls replace(content().duplicate()) by default.

Specified by:

duplicate in interface ByteBufHolder

Specified by:

duplicate in interface BulkStringRedisContent

Specified by:

duplicate in interface LastBulkStringRedisContent

Overrides:

duplicate in class DefaultByteBufHolder

retainedDuplicate

public FullBulkStringRedisMessage retainedDuplicate()

Description copied from class: DefaultByteBufHolder

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

This method calls replace(content().retainedDuplicate()) by default.

Specified by:

retainedDuplicate in interface ByteBufHolder

Specified by:

retainedDuplicate in interface BulkStringRedisContent

Specified by:

retainedDuplicate in interface LastBulkStringRedisContent

Overrides:

retainedDuplicate in class DefaultByteBufHolder

ByteBuf.retainedDuplicate()

replace

public FullBulkStringRedisMessage replace(ByteBuf content)

Description copied from class: DefaultByteBufHolder

Returns a new ByteBufHolder which contains the specified content.

Override this method to return a new instance of this object whose content is set to the specified content. The default implementation of DefaultByteBufHolder.copy(), DefaultByteBufHolder.duplicate() and DefaultByteBufHolder.retainedDuplicate() invokes this method to create a copy.

Specified by:

replace in interface ByteBufHolder

Specified by:

replace in interface BulkStringRedisContent

Specified by:

replace in interface LastBulkStringRedisContent

Overrides:

replace in class DefaultByteBufHolder

retain

retain

public FullBulkStringRedisMessage retain(int increment)

Description copied from interface: ReferenceCounted

Increases the reference count by the specified increment.

Specified by:

touch

public FullBulkStringRedisMessage touch()

Description copied from interface: ReferenceCounted
