BulkExportQueryCriteria

public BulkExportQueryCriteria(String tableName)

Constructs a query condition for a table with the given name.

参数:

tableName - The name of the table to query.

方法详细资料

setDataBlockType

public void setDataBlockType(DataBlockType dataBlockType)

getDataBlockType

public DataBlockType getDataBlockType()

Data type for row information

getInclusiveStartPrimaryKey

public PrimaryKey getInclusiveStartPrimaryKey()

Get the primary key value of the left boundary for the range query.

返回:

The primary key value of the left boundary for the range query.

setInclusiveStartPrimaryKey

public void setInclusiveStartPrimaryKey(PrimaryKey inclusiveStartPrimaryKey)

Range queries require the user to specify a range for the primary key. This range is a half-open interval that is closed on the left and open on the right, with inclusiveStartPrimaryKey being the left boundary of the interval. If direction is FORWARD, then inclusiveStartPrimaryKey must be less than exclusiveEndPrimaryKey. If direction is BACKWARD, then inclusiveStartPrimaryKey must be greater than exclusiveEndPrimaryKey. inclusiveStartPrimaryKey must include all primary key columns defined in the table. The values of the columns can be defined as PrimaryKeyValue.INF_MIN or PrimaryKeyValue.INF_MAX to represent the entire range of possible values for that column.

参数:

inclusiveStartPrimaryKey - The primary key value for the left boundary of the range query.

getExclusiveEndPrimaryKey

public PrimaryKey getExclusiveEndPrimaryKey()

Get the primary key value of the right boundary for the range query.

返回:

The primary key value of the right boundary for the range query.

setExclusiveEndPrimaryKey

public void setExclusiveEndPrimaryKey(PrimaryKey exclusiveEndPrimaryKey)

A range query requires the user to specify a range for a primary key. This range is a half-open interval that is closed on the left and open on the right, where exclusiveEndPrimaryKey is the right boundary of this interval. If direction is FORWARD, then exclusiveEndPrimaryKey must be greater than inclusiveStartPrimaryKey. If direction is BACKWARD, then exclusiveEndPrimaryKey must be less than inclusiveStartPrimaryKey. exclusiveEndPrimaryKey must include all primary key columns defined in the table. The values of the columns can be defined as PrimaryKeyValue.INF_MIN or PrimaryKeyValue.INF_MAX to represent the entire range of values for that column.

参数:

exclusiveEndPrimaryKey - The primary key value for the right boundary of the range query.

setTableName

public void setTableName(String tableName)

Sets the name of the table to query.

参数:

tableName - The name of the table.

getTableName

public String getTableName()

Returns the name of the queried table.

返回:

the name of the table

getColumnsToGet

public Set<String> getColumnsToGet()

Returns the list of column names to be read (read-only).

返回:

The list of column names (read-only).

addColumnsToGet

public void addColumnsToGet(String columnName)

Add the column to be read.

参数:

columnName - The name of the column to be returned.

addColumnsToGet

public void addColumnsToGet(String[] columnNames)

Add the columns to be read.

参数:

columnNames - The names of the columns to be returned.

addColumnsToGet

public void addColumnsToGet(Collection<String> columnsToGet)

Add the columns to be read.

参数:

columnsToGet -

clearColumnsToGet

public void clearColumnsToGet()

Clear the list of column names that have been set for reading.

numColumnsToGet

public int numColumnsToGet()

Returns the number of columns to be read.

返回:

The number of columns to be read.

setFilter

public void setFilter(Filter filter)

Set the Filter to be used for this query.

参数:

filter -

getFilter

public Filter getFilter()

Get the Filter used in this query.

返回:

Filter

抛出:

IllegalStateException - if the Filter is not set

hasSetFilter

public boolean hasSetFilter()

Check if the Filter is set.

返回:

Returns true if the Filter is set, otherwise returns false.

copyTo

public void copyTo(BulkExportQueryCriteria target)
