## Enum RecordSummaryFunctionType

- java.lang.Object
- - java.lang.Enum<RecordSummaryFunctionType>
  - - com.smartgwt.client.types.RecordSummaryFunctionType

- All Implemented Interfaces:
    ValueEnum, java.io.Serializable, java.lang.Comparable<RecordSummaryFunctionType>

      public enum RecordSummaryFunctionType
      extends java.lang.Enum<RecordSummaryFunctionType>
      implements ValueEnum

  Function to produce a summary value based on field values within a record. Example usage is record-level summaries in `"summary" type ListGrid fields`.

  SummaryFunctions may be specified in one of 2 ways:

  - as an explicit function or executable `StringMethod`. Takes 3 parameters:
    `record` the record for which the value is being calculated
    `fields` Array of listGridFields from which summaries should be calculated
    `summaryField` pointer to the summary type field on which the summary function is being run.
  - As a registered RecordSummaryFunction identifier
  Note that `DataSource.registerRecordSummaryFunction()` may be used to expand the set of registered RecordSummaryFunctions.

- - ### Enum Constant Summary

    Enum Constants
    Enum Constant and Description
    `AVG` Iterates through each field, picking up the numeric field values from the record and calculating the mean value.
    `MAX` Iterates through each field, picking up the numeric field values from the record and calculating the maximum value.
    `MIN` Iterates through each field, picking up the numeric field values from the record and calculating the minimum value.
    `MULTIPLIER` Iterates through each field, picking up the numeric field values from the record and multiplying them together.
    `SUM` Iterates through each field, picking up the numeric field values from the record and summing them.

  - ### Method Summary

    --- | ---
    `java.lang.String` | `getValue()`
    `static RecordSummaryFunctionType` | `valueOf(java.lang.String name)` Returns the enum constant of this type with the specified name.
    `static RecordSummaryFunctionType[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

    - #### SUM

          public static final RecordSummaryFunctionType SUM

      Iterates through each field, picking up the numeric field values from the record and summing them.

      If this enumerated value is used in a `Component XML` file or server-side DataSource descriptor (.ds.xml file), use the value "sum".

    - #### AVG

          public static final RecordSummaryFunctionType AVG

      Iterates through each field, picking up the numeric field values from the record and calculating the mean value.

      If this enumerated value is used in a `Component XML` file or server-side DataSource descriptor (.ds.xml file), use the value "avg".

    - #### MAX

          public static final RecordSummaryFunctionType MAX

      Iterates through each field, picking up the numeric field values from the record and calculating the maximum value.

      If this enumerated value is used in a `Component XML` file or server-side DataSource descriptor (.ds.xml file), use the value "max".

    - #### MIN

          public static final RecordSummaryFunctionType MIN

      Iterates through each field, picking up the numeric field values from the record and calculating the minimum value.

      If this enumerated value is used in a `Component XML` file or server-side DataSource descriptor (.ds.xml file), use the value "min".

    - #### MULTIPLIER

          public static final RecordSummaryFunctionType MULTIPLIER

      Iterates through each field, picking up the numeric field values from the record and multiplying them together.

      If this enumerated value is used in a `Component XML` file or server-side DataSource descriptor (.ds.xml file), use the value "multiplier".

  - ### Method Detail

    - #### values

          public static RecordSummaryFunctionType[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (RecordSummaryFunctionType c : RecordSummaryFunctionType.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static RecordSummaryFunctionType valueOf(java.lang.String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `java.lang.IllegalArgumentException` - if this enum type has no constant with the specified name
        `java.lang.NullPointerException` - if the argument is null

    - #### getValue

          public java.lang.String getValue()

      Specified by:
        `getValue` in interface `ValueEnum`
