                                                    TypedFieldId.Builder builder,
                                                    boolean addToBreadCrumb,
                                                    PathSegment seg)

getFieldIdIfMatches

public static TypedFieldId getFieldIdIfMatches(ValueVector vector,
                                               TypedFieldId.Builder builder,

Utility method to obtain TypedFieldId, providing metadata for specified field given by value vector used in code generation.

Parameters:

vector - a value vector the metadata is obtained for

builder - a builder instance gathering metadata

addToBreadCrumb - flag to indicate whether to include intermediate type

seg - path segment corresponding to the vector

Returns:

type metadata for given vector
