All Implemented Interfaces:

Term

Enclosing class:

Lists

public static class Lists.DelayedValue
extends Term.NonTerminal

Basically similar to a Value, but with some non-pure function (that need to be evaluated at execution time) in it. Note: this would also work for a list with bind markers, but we don't support that because 1) it's not excessively useful and 2) we wouldn't have a good column name to return in the ColumnSpecification for those markers (not a blocker per-se but we don't bother due to 1)).

Constructor Detail

DelayedValue

public DelayedValue(java.util.List<Term> elements)

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 Term.Terminal 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

getFunctions

public java.lang.Iterable<Function> getFunctions()
