Enum Constant Detail

MIN_START_TIME

public static final FlowRunColumn MIN_START_TIME

When the flow was started. This is the minimum of currently known application start times.

MAX_END_TIME

public static final FlowRunColumn MAX_END_TIME

When the flow ended. This is the maximum of currently known application end times.

FLOW_VERSION

public static final FlowRunColumn FLOW_VERSION

The version of the flow that this flow belongs to.

Method Detail

values

public static FlowRunColumn[] 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 (FlowRunColumn c : FlowRunColumn.values())
    System.out.println(c);

Returns:

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

valueOf

public static FlowRunColumn 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

getColumnQualifierBytes

public byte[] getColumnQualifierBytes()

Description copied from interface: Column

Get byte representation for this column qualifier.

Specified by:

getColumnQualifierBytes in interface Column<FlowRunTable>

Returns:

a byte array representing column qualifier.

getColumnFamilyBytes

public byte[] getColumnFamilyBytes()

Description copied from interface: Column

Returns column family name(as bytes) associated with this column.

Specified by:

getColumnFamilyBytes in interface Column<FlowRunTable>

Returns:

a byte array encoding column family for this column qualifier.

getAggregationOperation

public AggregationOperation getAggregationOperation()

getValueConverter

public ValueConverter getValueConverter()

Description copied from interface: Column

Returns value converter implementation associated with this column.

Specified by:

getValueConverter in interface Column<FlowRunTable>

Returns:

a ValueConverter implementation.

getCombinedAttrsWithAggr

public Attribute[] getCombinedAttrsWithAggr(Attribute... attributes)

Description copied from interface: Column

Return attributed combined with aggregations, if any.

Specified by:

getCombinedAttrsWithAggr in interface Column<FlowRunTable>

Returns:

an array of Attributes

supplementCellTimestamp

public boolean supplementCellTimestamp()

Description copied from interface: Column

Return true if the cell timestamp needs to be supplemented.

Specified by:

supplementCellTimestamp in interface Column<FlowRunTable>

Returns:

true if the cell timestamp needs to be supplemented
