Method Detail

colDescFromThrift

public static HColumnDescriptor colDescFromThrift(ColumnDescriptor in)
                                           throws IllegalArgument

This utility method creates a new Hbase HColumnDescriptor object based on a Thrift ColumnDescriptor "struct".

Parameters:

in - Thrift ColumnDescriptor object

Returns:

HColumnDescriptor

Throws:

IllegalArgument

colDescFromHbase

public static ColumnDescriptor colDescFromHbase(HColumnDescriptor in)

This utility method creates a new Thrift ColumnDescriptor "struct" based on an Hbase HColumnDescriptor object.

Parameters:

in - Hbase HColumnDescriptor object

Returns:

Thrift ColumnDescriptor

cellFromHBase

public static List<TCell> cellFromHBase(Cell in)

This utility method creates a list of Thrift TCell "struct" based on an Hbase Cell object. The empty list is returned if the input is null.

Parameters:

in - Hbase Cell object

Returns:

Thrift TCell array

cellFromHBase

public static List<TCell> cellFromHBase(Cell[] in)

This utility method creates a list of Thrift TCell "struct" based on an Hbase Cell array. The empty list is returned if the input is null.

Parameters:

in - Hbase Cell array

Returns:

Thrift TCell array

rowResultFromHBase

public static List<TRowResult> rowResultFromHBase(Result[] in,
                                  boolean sortColumns)

This utility method creates a list of Thrift TRowResult "struct" based on an Hbase RowResult object. The empty list is returned if the input is null.

Parameters:

in - Hbase RowResult object

sortColumns - This boolean dictates if row data is returned in a sorted order sortColumns = True will set TRowResult's sortedColumns member which is an ArrayList of TColumn struct sortColumns = False will set TRowResult's columns member which is a map of columnName and TCell struct

Returns:

Thrift TRowResult array

rowResultFromHBase

public static List<TRowResult> rowResultFromHBase(Result[] in)

This utility method creates a list of Thrift TRowResult "struct" based on an array of Hbase RowResult objects. The empty list is returned if the input is null.

Parameters:

in - Array of Hbase RowResult objects

Returns:

Thrift TRowResult array

rowResultFromHBase

public static List<TRowResult> rowResultFromHBase(Result in)

incrementFromThrift

public static Increment incrementFromThrift(TIncrement tincrement)

From a TIncrement create an Increment.

Parameters:

tincrement - the Thrift version of an increment

Returns:

an increment that the TIncrement represented.

appendFromThrift

public static Append appendFromThrift(TAppend tappend)

From a TAppend create an Append.

Parameters:

tappend - the Thrift version of an append.

Returns:

an increment that the TAppend represented.
