Method Detail

getIdentifierKey
```
public CanonKey getIdentifierKey()
```
Producer-only identity; never serialized or reconstructed from display text.

setIdentifierKey

public void setIdentifierKey(CanonKey identifierKey)

getFieldPathKey
```
public Object getFieldPathKey()
```
Producer-only: the structural identity of a STRUCT field path node, its declared column and its path, by which an output merge tells two field nodes apart whose displays collide (s."a.b".c and s.a.b.c) and keeps one node for two spellings of one field; null for any other column. Never serialized (plan section 4.7).

setFieldPathKey

public void setFieldPathKey(Object fieldPathKey)

getSqlSpelling
```
public String getSqlSpelling()
```
Producer-only: the column's spelling as SQL when the producer knows it (the column a star link of an identity names), from which an output merge gives two columns of one table whose names collide names that tell them apart. Never serialized.

setSqlSpelling

public void setSqlSpelling(String sqlSpelling)

standsForStar
```
public boolean standsForStar()
```
Whether this column stands for a star (*, t.*, a whole-row pseudo column). Output version 1 names a star *; a column NAMED * (SQL Server [*], BigQuery `*`) is shown the same way, so the document says star="false" on it. Never decided from the name alone.

getStar
```
public Boolean getStar()
```
The star marker as written: false on a column named * that is not a star, else absent.

setStar
```
public void setStar(Boolean star)
```

```
public String getCoordinate()
```

appendCoordinate

public void appendCoordinate(String coordinate)

setCoordinate

public void setCoordinate(String coordinate)
