RUN_ID

public static final FlowActivityColumnPrefix RUN_ID

To store run ids of the flows.

Method Detail

values

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

Returns:

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

valueOf

public static FlowActivityColumnPrefix 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

getColumnPrefix

public java.lang.String getColumnPrefix()

Returns:

the column name value

getColumnPrefixBytes

public byte[] getColumnPrefixBytes(byte[] qualifierPrefix)

Specified by:

getColumnPrefixBytes in interface ColumnPrefix<FlowActivityTable>

Parameters:

qualifierPrefix - Column qualifier or prefix of qualifier.

Returns:

a byte array encoding column prefix and qualifier/prefix passed.

getColumnPrefixBytes

public byte[] getColumnPrefixBytes(java.lang.String qualifierPrefix)

Specified by:

getColumnPrefixBytes in interface ColumnPrefix<FlowActivityTable>

Parameters:

qualifierPrefix - Column qualifier or prefix of qualifier.

Returns:

a byte array encoding column prefix and qualifier/prefix passed.

getColumnPrefixBytes

public byte[] getColumnPrefixBytes()

getColumnFamilyBytes

public byte[] getColumnFamilyBytes()

Description copied from interface: ColumnPrefix

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

Specified by:

getColumnFamilyBytes in interface ColumnPrefix<FlowActivityTable>

Returns:

a byte array encoding column family for this prefix.

getColumnPrefixInBytes

public byte[] getColumnPrefixInBytes()

Description copied from interface: ColumnPrefix

Get the column prefix in bytes.

Specified by:

getColumnPrefixInBytes in interface ColumnPrefix<FlowActivityTable>

Returns:

column prefix in bytes

getValueConverter

public ValueConverter getValueConverter()

Description copied from interface: ColumnPrefix

Returns value converter implementation associated with this column prefix.

Specified by:

getValueConverter in interface ColumnPrefix<FlowActivityTable>

Returns:

a ValueConverter implementation.

getCombinedAttrsWithAggr

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

Description copied from interface: ColumnPrefix

Return attributed combined with aggregations, if any.

Specified by:

getCombinedAttrsWithAggr in interface ColumnPrefix<FlowActivityTable>

Returns:

an array of Attributes

supplementCellTimeStamp

public boolean supplementCellTimeStamp()

Description copied from interface: ColumnPrefix

Return true if the cell timestamp needs to be supplemented.

Specified by:

supplementCellTimeStamp in interface ColumnPrefix<FlowActivityTable>

Returns:

true if the cell timestamp needs to be supplemented

getAttribute

public AggregationOperation getAttribute()
