entryEOF
protected boolean entryEOF
- this flag is set to true after EOF has reached for one entry
ArchiveStream
public ArchiveStream(AbstractStream clientStream)
- For use of customised checksum routines
read
public int read()
throws java.io.IOException
- Description copied from class:
AbstractStream
- Reads a byte of data from this file. This method blocks if no
input is yet available.
- Overrides:
read
in class AbstractStream
- Following copied from class:
com.bigzip.plugin.compression.io.AbstractStream
- Returns:
- the next byte of data, or
-1
if the end of the
file is reached.
read
public int read(byte[] b,
int off,
int len)
throws java.io.IOException
- Description copied from class:
AbstractStream
- Reads up to
len
bytes of data from this file into an
array of bytes. This method blocks until at least one byte of input
is available.
- Overrides:
read
in class AbstractStream
- Following copied from class:
com.bigzip.plugin.compression.io.AbstractStream
- Parameters:
b
- the buffer into which the data is read.off
- the start offset of the data.len
- the maximum number of bytes read.- Returns:
- the total number of bytes read into the buffer, or
-1
if there is no more data because the end of
the file has been reached.
write
public void write(int b)
throws java.io.IOException
- Description copied from class:
AbstractStream
- Writes the specified byte to this file.
- Overrides:
write
in class AbstractStream
- Following copied from class:
com.bigzip.plugin.compression.io.AbstractStream
- Parameters:
b
- the byte
to be written.
write
public void write(byte[] b,
int off,
int len)
throws java.io.IOException
- Description copied from class:
AbstractStream
- Writes
len
bytes from the specified byte array
starting at offset off
to this file.
- Overrides:
write
in class AbstractStream
- Following copied from class:
com.bigzip.plugin.compression.io.AbstractStream
- Parameters:
b
- the data.off
- the start offset in the data.len
- the number of bytes to write.
available
public int available()
throws java.io.IOException
- Returns 0 after EOF has reached for the current entry data,
otherwise always return 1.
Programs should not count on this method to return the actual number
of bytes that could be read without blocking.
- Returns:
- 1 before EOF and 0 after EOF has reached for current entry.
- Throws:
java.io.IOException
- if an I/O error occurs.
skipBytes
public int skipBytes(int n)
throws java.io.IOException
- Skips specified number of bytes in the current entry. If the entry's
EOF is reached then entryEOF is set to true and the skipping is
stopped.
- Overrides:
skipBytes
in class AbstractStream
- Parameters:
n
- the number of bytes to skip- Returns:
- the actual number of bytes skipped
- Throws:
java.io.IOException
- if an I/O error has occurredjava.lang.IllegalArgumentException
- if n < 0
setEntryEOF
public void setEntryEOF(boolean b)
- Resets the entryEOF state so that the next entry can be read.
- Parameters:
b
- entryEOF state
isEntryEOF
public boolean isEntryEOF()
- Returns:
- where or not the end of the entry has been reached.
