liquibase.change.ColumnConfig
All Implemented Interfaces:
LiquibaseSerializable
Direct Known Subclasses:
AddColumnConfig, LoadDataColumnConfig
public class ColumnConfig extends AbstractLiquibaseSerializable
The standard configuration used by Change classes to represent a column. It is not required that a column-based Change uses this class, but parsers should look for it so it is a helpful convenience. The definitions of "defaultValue" and "value" will vary based on the Change and may not be applicable in all cases.

  • Constructor Details

    • ColumnConfig

      public ColumnConfig(Column columnSnapshot)
      Create a ColumnConfig object based on a Column snapshot. It will attempt to set as much as possible based on the information in the snapshot.

    • ColumnConfig

      public ColumnConfig()
      Create am empty ColumnConfig object. Boolean and other object values will default to null.

  • Method Details

    • fromName

      public static ColumnConfig fromName(String name)

    • arrayFromNames

      public static ColumnConfig[] arrayFromNames(String names)

    • getName

      public String getName()
      The name of the column.

    • setName

      public ColumnConfig setName(String name)

    • setName

      public ColumnConfig setName(String name, boolean computed)

    • getComputed

      public Boolean getComputed()

    • setComputed

      public ColumnConfig setComputed(Boolean computed)

    • getType

      public String getType()
      The data type fof the column. This value will pass through DataTypeFactory.fromDescription(String, liquibase.database.Database) before being included in SQL.

    • setType

      public ColumnConfig setType(String type)

    • getValue

      public String getValue()
      The String value to set this column to. If you do not want the value set by setValue(String) use a more specific function like getValueNumeric() or the more generic getValueObject()

      If performing an data manipulation operation, the setValue* functions should be used to set what the columns should be set to. If performing a data definition operation, this setValue* functions should be used to set what existing rows should be set to (may be different than the default value for new rows)

    • setValue

      public ColumnConfig setValue(String value)
      Sets the string value this column should be set to. If you are trying to set a value type other than a string, use the more specific functions like setValueNumeric(Number). This method does no processing of the string. Any trimming is expected to be done beforehand. It does not convert the string "null" to null so that you can set the string "null" as a value if you are feeling particularly crazy.

    • getValueNumeric

      public Number getValueNumeric()
      Return the numeric value this column should be set to.
      See Also:

    • setValueNumeric

      public ColumnConfig setValueNumeric(Number valueNumeric)

    • setValueNumeric

      public ColumnConfig setValueNumeric(String valueNumeric)
      Set the number this column should be set to. Supports integers and decimals, and strips off any wrapping parentheses. If the passed value cannot be parsed as a number in US locale, it is assumed to be a function that returns a number. If the value "null" is passed, it will set a null value.

    • getValueBoolean

      public Boolean getValueBoolean()
      Return the boolean value this column should be set to.
      See Also:

    • setValueBoolean

      public ColumnConfig setValueBoolean(String valueBoolean)
      Set the valueBoolean based on a given string. If the passed value cannot be parsed as a boolean, it is assumed to be a function that returns a boolean. If the string "null" or an empty string is passed, it will set a null value. If "1" is passed, defaultValueBoolean is set to true. If 0 is passed, defaultValueBoolean is set to false

    • setValueBoolean

      public ColumnConfig setValueBoolean(Boolean valueBoolean)

    • getValueComputed

      public DatabaseFunction getValueComputed()

    • getValueDate

      public Date getValueDate()
      Return the date value this column should be set to.
      See Also:

    • setValueDate

      public ColumnConfig setValueDate(String valueDate) throws DateParseException
      Set the date this column should be set to. Supports any of the date or datetime formats handled by ISODateFormat. If the passed value cannot be parsed as a date, it is assumed to be a function that returns a date. If the string "null" is passed, it will set a null value.
      Parameters:
      valueDate - the Date Value to use (may be null or "null", or start with "now" or "today").
      Throws:
      DateParseException - if the columnType isn't supported for "now" or "today" values.

    • setDefaultValue

      public ColumnConfig setDefaultValue(String defaultValue)
      Sets the string default value to assign to this column. If you are trying to set a default value type other than a string, use the more specific functions like setDefaultValueNumeric(Number). This method does no processing of the string. Any trimming is expected to be done beforehand. It does not convert the string "null" to null so that you can set the string "null" as a value if you are feeling particularly crazy.
