Class Term.Terminal

java.lang.Object
  org.apache.cassandra.cql3.Term.Terminal

All Implemented Interfaces:

Term

Direct Known Subclasses:

Constants.Value, Lists.Value, Maps.Value, Sets.Value

Enclosing interface:

Term

public abstract static class Term.Terminal
extends java.lang.Object
implements Term

A terminal term, i.e. one without any bind marker. This can be only one of: - a constant value - a collection value Note that a terminal term will always have been type checked, and thus consumer can (and should) assume so.

Method Detail

collectMarkerSpecification

public void collectMarkerSpecification(ColumnSpecification[] boundNames)

Description copied from interface: Term

Collects the column specification for the bind variables in this Term. This is obviously a no-op if the term is Terminal.

Specified by:

collectMarkerSpecification in interface Term

Parameters:

boundNames - the list of column specification where to collect the bind variables of this term in.

bind

public Term.Terminal bind(java.util.List<java.nio.ByteBuffer> values)

Description copied from interface: Term

Bind the values in this term to the values contained in values. This is obviously a no-op if the term is Terminal.

Specified by:

bind in interface Term

Parameters:

values - the values to bind markers to.

Returns:

the result of binding all the variables of this NonTerminal (or 'this' if the term is terminal).

get

public abstract java.nio.ByteBuffer get()

Returns:

the serialized value of this terminal.

bindAndGet

public java.nio.ByteBuffer bindAndGet(java.util.List<java.nio.ByteBuffer> values)
                               throws InvalidRequestException

Description copied from interface: Term

A shorter for bind(values).get(). We expose it mainly because for constants it can avoids allocating a temporary object between the bind and the get (note that we still want to be able to separate bind and get for collections).

Specified by:

bindAndGet in interface Term

Throws:

InvalidRequestException
