ToBlobFunction

public ToBlobFunction(CQL3Type fromType)

Method Details

public ByteBuffer execute(Arguments arguments)

Description copied from interface: ScalarFunction

Applies this function to the specified arguments.

Parameters:

arguments - the input arguments for the function

Returns:

the result of applying this function to the arguments

withLegacyName

public NativeFunction withLegacyName()

Description copied from class: NativeFunction

Returns a copy of this function using its old pre-5.0 name before the adoption of snake-cased function names. Those naming conventions were adopted in 5.0, but we still need to support the old names for compatibility. See CASSANDRA-18037 for further details.

Overrides:

withLegacyName in class NativeFunction

Returns:

a copy of this function using its old pre-5.0 deprecated name, or null if the pre-5.0 function name already satisfied the naming conventions.

newArguments

public Arguments newArguments(ProtocolVersion version)

Description copied from interface: Function

Creates some new input arguments for this function.

Specified by:

newArguments in interface Function

Overrides:

newArguments in class NativeFunction

Parameters:

version - the protocol version

Returns:

some new input arguments for this function
