org.apache.hadoop.hbase.io.hfile中HFile.Reader的使用

实现HFile.Reader的org.apache.hadoop.hbase.io.hfile中的类

限定符和类型	类和说明
class	HFileReaderImpl Implementation that can handle all hfile versions of HFile.Reader.

声明为HFile.Reader的org.apache.hadoop.hbase.io.hfile中的字段

限定符和类型	字段和说明
protected HFile.Reader	HFileReaderImpl.HFileScannerImpl.reader

返回HFile.Reader的org.apache.hadoop.hbase.io.hfile中的方法

限定符和类型	方法和说明
static HFile.Reader	HFile.createReader(org.apache.hadoop.fs.FileSystem fs, org.apache.hadoop.fs.Path path, CacheConfig cacheConf, boolean primaryReplicaReader, org.apache.hadoop.conf.Configuration conf)
static HFile.Reader	HFile.createReader(org.apache.hadoop.fs.FileSystem fs, org.apache.hadoop.fs.Path path, org.apache.hadoop.conf.Configuration conf) Creates reader with cache configuration disabled
static HFile.Reader	HFile.createReader(org.apache.hadoop.fs.FileSystem fs, org.apache.hadoop.fs.Path path, FSDataInputStreamWrapper fsdis, long size, CacheConfig cacheConf, boolean primaryReplicaReader, org.apache.hadoop.conf.Configuration conf) The sockets and the file descriptors held by the method parameter FSDataInputStreamWrapper passed will be freed after its usage so caller needs to ensure that no other threads have access to the same passed reference.
HFile.Reader	HFileScanner.getReader()
HFile.Reader	HFileReaderImpl.HFileScannerImpl.getReader()

参数类型为HFile.Reader的org.apache.hadoop.hbase.io.hfile中的构造器

构造器和说明

EncodedScanner(HFile.Reader reader, boolean cacheBlocks, boolean pread, boolean isCompaction, HFileContext meta)
HFileScannerImpl(HFile.Reader reader, boolean cacheBlocks, boolean pread, boolean isCompaction)

返回HFile.Reader的org.apache.hadoop.hbase.regionserver中的方法

限定符和类型	方法和说明
HFile.Reader	StoreFileReader.getHFileReader()

org.apache.hadoop.hbase.util中HFile.Reader的使用

参数类型为HFile.Reader的org.apache.hadoop.hbase.util中的方法

限定符和类型	方法和说明
static BloomFilter	BloomFilterFactory.createFromMeta(DataInput meta, HFile.Reader reader) Instantiates the correct Bloom filter class based on the version provided in the meta block data.
