All Implemented Interfaces:

Term

Enclosing class:

Tuples

public static class Tuples.DelayedValue

Method Detail

containsBindMarker

public boolean containsBindMarker()

Description copied from interface: Term

Whether or not that term contains at least one bind marker. Note that this is slightly different from being or not a NonTerminal, because calls to non pure functions will be NonTerminal (see #5616) even if they don't have bind markers.

collectMarkerSpecification

public void collectMarkerSpecification(VariableSpecifications 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.

Parameters:

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

bind

public Tuples.Value bind(QueryOptions options)
                  throws InvalidRequestException

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.

Parameters:

options - the values to bind markers to.

Returns:

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

Throws:

InvalidRequestException

bindAndGet

public java.nio.ByteBuffer bindAndGet(QueryOptions options)
                               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

Overrides:

bindAndGet in class Term.NonTerminal

Throws:

InvalidRequestException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

addFunctionsTo

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