Field Detail

UNSET_LIST

static final java.util.List UNSET_LIST

The List returned when the list was not set.

Method Detail

addFunctionsTo

void addFunctionsTo(java.util.List<Function> functions)

Adds all functions (native and user-defined) used by any of the terms to the specified list.

Parameters:

functions - the list to add to

collectMarkerSpecification

void collectMarkerSpecification(VariableSpecifications boundNames)

Collects the column specifications for the bind variables in the terms. This is obviously a no-op if the terms are Terminal.

Parameters:

boundNames - the variables specification where to collect the bind variables of the terms in.

bind

java.util.List<Term.Terminal> bind(QueryOptions options)

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

Parameters:

options - the values to bind markers to.

Returns:

the result of binding all the variables of these NonTerminals or an UNSET_LIST if the term was unset.

bindAndGet

java.util.List<java.nio.ByteBuffer> bindAndGet(QueryOptions options)

ofListMarker

static Terms ofListMarker(Lists.Marker marker,
                          AbstractType<?> type)

Creates a Terms for the specified list marker.

Parameters:

marker - the list marker

type - the element type

Returns:

a Terms for the specified list marker

of

static Terms of(Term term)

Creates a Terms containing a single Term.

Parameters:

term - the Term

Returns:

a Terms containing a single Term.

of

static Terms of(java.util.List<Term> terms)

Creates a Terms containing a set of Term.

Parameters:

term - the Term

Returns:

a Terms containing a set of Term.

addFunctions

static void addFunctions(java.lang.Iterable<Term> terms,
                         java.util.List<Function> functions)

Adds all functions (native and user-defined) of the specified terms to the list.

Parameters:

functions - the list to add to

asBytes

static java.nio.ByteBuffer asBytes(java.lang.String keyspace,
                                   java.lang.String term,
                                   AbstractType type)
