Constructor Details

Column

public Column(String columnName,
int position)

Create a column definition. By default, it sets `nullable` to `true`, and the `type` to `UNKNOWN`

Parameters:

columnName - the columnName

position - the column position

Column

public Column(String columnName,
int position,
boolean nullable)

Create a column definition. Sets the `type` to `UNKNOWN`

Parameters:

columnName - the column name

position - the column position (zero-based)

nullable - specifies whether the data for this column can have null values - if set to false and a null/empty value occurs an error will be thrown

Column

public Column(String columnName,
int position,
boolean nullable,
JSONValueType type)

Create a column definition

Parameters:

columnName - the column name

position - the column position

nullable - specifies whether data for this column can have null values. If set to false and a null/empty value occurs, an error will be thrown

type - the data type

Method Details

setColumnName

public void setColumnName(String columnName)

Set the column name

Parameters:

columnName - the column name

getColumnName

public String getColumnName()

Get the column name

Returns:

the column name

setType

public void setType(JSONValueType type)

Set the column data type

Parameters:

type - the data type

getType

public JSONValueType getType()

get the column data type

Returns:

the column data type

setPosition

public void setPosition(int position)

Set the column position (zero-based)

Parameters:

position - the column position

getPosition

public int getPosition()

Get the column position (zero-based)

Returns:

the column position

setNullable

public void setNullable(boolean nullable)

Sets whether the column can have null values. This is useful for data and number fields, but can be used for String fields as well.

Parameters:

nullable - sets whether column can have null values

isNullable

public boolean isNullable()

Gets whether column can have null values.

Returns:

true if the field can have null values; false otherwise. For Strings, if the value is false, the expectation is to create an empty String value. For numbers, if the value is false, then it is expected to return 0. For dates, if the date is false, an error will occur.
