Properties

AllowLiterals

TypeDescription
bool

NamedBindings

public MapField<string, GqlQueryParameter> NamedBindings { get; }

For each non-reserved named binding site in the query string, there must be a named parameter with that name, but not necessarily the inverse.

Key must match regex [A-Za-z_$][A-Za-z_$0-9]*, must not match regex __.*__, and must not be "".

PositionalBindings

public RepeatedField<GqlQueryParameter> PositionalBindings { get; }

Numbered binding site @1 references the first numbered parameter, effectively using 1-based indexing, rather than the usual 0.

For each binding site numbered i in query_string, there must be an i-th numbered parameter. The inverse must also be true.
