Interface RowQuery<K,C>

Type Parameters:

K -

C -

All Superinterfaces:

com.netflix.astyanax.Execution<ColumnList<C>>

public interface RowQuery<K,C>
extends com.netflix.astyanax.Execution<ColumnList<C>>

Interface to narrow down the path and column slices within a query after the keys were seleted using the ColumnFamilyQuery.

Method Summary

RowQuery<K,C>	autoPaginate(boolean enabled) When used in conjunction with a column range this will call subsequent calls to execute() to get the next block of columns.
RowCopier<K,C>	copyTo(ColumnFamily<K,C> columnFamily, K rowKey) Copy the results of the query to another column family
ColumnQuery<C>	getColumn(C column) Specify the path to a single column (either Standard or Super).
ColumnCountQuery	getCount() Returns the number of columns in the response without returning any data
RowQuery<K,C>	setIsPaginating() Deprecated.
RowQuery<K,C>	withColumnRange(java.nio.ByteBuffer startColumn, java.nio.ByteBuffer endColumn, boolean reversed, int count) Specify a range and provide pre-constructed start and end columns.
RowQuery<K,C>	withColumnRange(ByteBufferRange range) Specify a range of composite columns.
RowQuery<K,C>	withColumnRange(C startColumn, C endColumn, boolean reversed, int count) Specify a range of columns to return.
RowQuery<K,C>	withColumnSlice(C... columns) Specify a non-contiguous set of columns to retrieve.
RowQuery<K,C>	withColumnSlice(java.util.Collection<C> columns) Specify a non-contiguous set of columns to retrieve.
RowQuery<K,C>	withColumnSlice(ColumnSlice<C> columns) Use this when your application caches the column slice.

Method Detail

getColumn

ColumnQuery<C> getColumn(C column)

Specify the path to a single column (either Standard or Super). Notice that the sub column type and serializer will be used now.

Type Parameters:

C2 -

Parameters:

path -

withColumnSlice

RowQuery<K,C> withColumnSlice(java.util.Collection<C> columns)

Specify a non-contiguous set of columns to retrieve.

Parameters:

columns -

withColumnSlice

RowQuery<K,C> withColumnSlice(C... columns)

Specify a non-contiguous set of columns to retrieve.

Parameters:

columns -

withColumnSlice

RowQuery<K,C> withColumnSlice(ColumnSlice<C> columns)

Use this when your application caches the column slice.

Parameters:

slice -

withColumnRange

RowQuery<K,C> withColumnRange(C startColumn,
                              C endColumn,
                              boolean reversed,
                              int count)

Specify a range of columns to return. Use this for simple ranges for non-composite column names. For Composite column names use withColumnRange(ByteBufferRange range) and the AnnotatedCompositeSerializer.buildRange()

Parameters:

startColumn - First column in the range

endColumn - Last column in the range

reversed - True if the order should be reversed. Note that for reversed, startColumn should be greater than endColumn.

count - Maximum number of columns to return (similar to SQL LIMIT)

withColumnRange

RowQuery<K,C> withColumnRange(java.nio.ByteBuffer startColumn,
                              java.nio.ByteBuffer endColumn,
                              boolean reversed,
                              int count)

Specify a range and provide pre-constructed start and end columns. Use this with Composite columns

Parameters:

startColumn -

endColumn -

reversed -

count -

withColumnRange

RowQuery<K,C> withColumnRange(ByteBufferRange range)

Specify a range of composite columns. Use this in conjunction with the AnnotatedCompositeSerializer.buildRange().

Parameters:

range -

setIsPaginating

@Deprecated
RowQuery<K,C> setIsPaginating()

Deprecated.

autoPaginate

RowQuery<K,C> autoPaginate(boolean enabled)

When used in conjunction with a column range this will call subsequent calls to execute() to get the next block of columns.

copyTo

RowCopier<K,C> copyTo(ColumnFamily<K,C> columnFamily,
                      K rowKey)

Copy the results of the query to another column family

Parameters:

columnFamily -

otherRowKey -

getCount

ColumnCountQuery getCount()

Returns the number of columns in the response without returning any data

Throws:

com.netflix.astyanax.connectionpool.exceptions.ConnectionException
