构造器详细资料

IndexSharedStringTable

public IndexSharedStringTable()
                       throws IOException

Create a temp file to storage the index

抛出:

IOException - if I/O error occur.

IndexSharedStringTable

public IndexSharedStringTable(Path path)
                       throws IOException

Constructor a IndexSharedStringTable with a exists index file

参数:

path - the index file path

抛出:

IOException - if file not exists or I/O error occur.

方法详细资料

setShortSectorSize

public void setShortSectorSize(int sssz)

Size of a short-sector in the index stream in power-of-two (sssz), real short-sector size is short_sec_size = 2^sssz bytes (maximum value is sector size ssz,

参数:

sssz - the short-sector size

push

public int push(char c)
         throws IOException

Write character value into table

覆盖:

push 在类中 SharedStringTable

参数:

c - the character value

返回:

the value index of table

抛出:

IOException - if I/O error occur

push

public int push(String key)
         throws IOException

Write string value into table

覆盖:

push 在类中 SharedStringTable

参数:

key - the string value

返回:

the value index of table

抛出:

IOException - if I/O error occur

get

public String get(int index)
           throws IOException

Getting by index

参数:

index - the value's index in table

返回:

the string value at index

抛出:

IOException - if I/O error occur

get

public int get(int fromIndex,
               String[] array)
        throws IOException

Batch getting

参数:

fromIndex - the index of the first element, inclusive, to be sorted

array - Destination array

返回:

The number of string read, or -1 if the end of the stream has been reached

抛出:

IOException - if I/O error occur

close

public void close()
           throws IOException

从类复制的说明: SharedStringTable

Close channel and delete temp files

close 在类中 SharedStringTable

抛出:

IOException - if I/O error occur

checkCapacityAndGrow

protected boolean checkCapacityAndGrow()

Check remaining data and grow if shortage

覆盖:

checkCapacityAndGrow 在类中 SharedStringTable

返回:

true/false
