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

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 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
