RangeRowQueryCriteria

public RangeRowQueryCriteria(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

getLimit

public int getLimit()

Get the maximum number of rows returned during the operation. -1 means returning all rows within the result (default value).

返回:

The maximum number of rows returned in this operation.

setLimit

public void setLimit(int limit)

Set the number of rows returned per request during the query. -1 indicates all data rows that meet the conditions (default value).

参数:

limit - The number of rows returned per request.

getDirection

public Direction getDirection()

Get the read order of the range query (forward(FORWARD) or backward(BACKWARD)).

返回:

read order

setDirection

public void setDirection(Direction direction)

Set the read order (forward(FORWARD) or backward(BACKWARD)) for the range query.

参数:

direction - Read order

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)

A range query requires the user to specify a range of primary keys. This range is a half-open interval that is closed on the left and open on the right, with inclusiveStartPrimaryKey as the left boundary of the interval. If direction is FORWARD, inclusiveStartPrimaryKey must be less than exclusiveEndPrimaryKey. If direction is BACKWARD, 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)

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 exclusiveEndPrimaryKey being the right boundary of the 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 full range of possible values for that column.

参数:

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

getToken

public byte[] getToken()

setToken

public void setToken(byte[] token)

hasSetToken

public boolean hasSetToken()
