org.apache.hadoop.hbase.security.access.TablePermission

所有已实现的接口:

org.apache.hadoop.io.Writable

@InterfaceAudience.Public
public class TablePermission
extends Permission

Represents an authorization for access for the given actions, optionally restricted to the given column family or column qualifier, over the given table. If the family property is null, it implies full table access.

方法详细资料

getTableName

public TableName getTableName()

hasFamily

public boolean hasFamily()

getFamily

public byte[] getFamily()

hasQualifier

public boolean hasQualifier()

getQualifier

public byte[] getQualifier()

getNamespace

public String getNamespace()

implies

public boolean implies(TableName table,
                       byte[] family,
                       byte[] qualifier,
                       Permission.Action action)

Check if given action can performs on given table:family:qualifier.

参数:

table - table name

family - family name

qualifier - qualifier name

action - one of [Read, Write, Create, Exec, Admin]

返回:

true if can, false otherwise

implies

public boolean implies(TableName table,
                       byte[] family,
                       Permission.Action action)

Check if given action can performs on given table:family.

参数:

table - table name

family - family name

action - one of [Read, Write, Create, Exec, Admin]

返回:

true if can, false otherwise

implies

public boolean implies(TableName table,
                       KeyValue kv,
                       Permission.Action action)

Checks if this permission grants access to perform the given action on the given table and key value.

参数:

table - the table on which the operation is being performed

kv - the KeyValue on which the operation is being requested

action - the action requested

返回:

true if the action is allowed over the given scope by this permission, otherwise false

tableFieldsEqual

public boolean tableFieldsEqual(TablePermission tp)

Check if fields of table in table permission equals.

参数:

tp - to be checked table permission

返回:

true if equals, false otherwise

equalsExceptActions

public boolean equalsExceptActions(Object obj)

从类复制的说明: Permission

Check if two permission equals regardless of actions. It is useful when merging a new permission with an existed permission which needs to check two permissions's fields.

覆盖:

equalsExceptActions 在类中 Permission

参数:

obj - instance

返回:

true if equals, false otherwise

equals

public boolean equals(Object obj)

覆盖:

equals 在类中 Permission

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Permission

toString

public String toString()

覆盖:

toString 在类中 Permission

rawExpression

protected String rawExpression()

覆盖:

rawExpression 在类中 Permission

readFields

public void readFields(DataInput in)
                throws IOException

指定者:

readFields 在接口中 org.apache.hadoop.io.Writable

覆盖:

readFields 在类中 Permission

抛出:

IOException

write

public void write(DataOutput out)
           throws IOException

指定者:

write 在接口中 org.apache.hadoop.io.Writable

覆盖:

write 在类中 Permission

抛出:

IOException
