Method Details- 
closeCloses this content.- Specified by:
- closein interface- AutoCloseable
- Specified by:
- closein interface- Closeable
- Specified by:
- closein interface- RandomAccessContent
- Throws:
- IOException- if an error occurs.
 
- 
getFilePointerDescription copied from interface:RandomAccessContentReturns the current offset in this file.- Specified by:
- getFilePointerin interface- RandomAccessContent
- Returns:
- the offset from the beginning of the file, in bytes, at which the next read or write occurs.
- Throws:
- IOException- if an I/O error occurs.
 
- 
getInputStreamDescription copied from interface:RandomAccessContentGets the input stream.Notice: If you use RandomAccessContent.seek(long)you have to re-get the InputStream- Specified by:
- getInputStreamin interface- RandomAccessContent
- Returns:
- the InputStream.
- Throws:
- IOException- if an I/O error occurs.
 
- 
lengthDescription copied from interface:RandomAccessContentReturns the length of this file.- Specified by:
- lengthin interface- RandomAccessContent
- Returns:
- the length of this file, measured in bytes.
- Throws:
- IOException- if an I/O error occurs.
 
- 
onCloseCalled after this stream is closed.- Throws:
- IOException- if subclass throws it.
 
- 
readBoolean- Specified by:
- readBooleanin interface- DataInput
- Throws:
- IOException
 
- 
readByte- Specified by:
- readBytein interface- DataInput
- Throws:
- IOException
 
- 
readChar- Specified by:
- readCharin interface- DataInput
- Throws:
- IOException
 
- 
readDouble- Specified by:
- readDoublein interface- DataInput
- Throws:
- IOException
 
- 
readFloat- Specified by:
- readFloatin interface- DataInput
- Throws:
- IOException
 
- 
readFully- Specified by:
- readFullyin interface- DataInput
- Throws:
- IOException
 
- 
readFully- Specified by:
- readFullyin interface- DataInput
- Throws:
- IOException
 
- 
readInt- Specified by:
- readIntin interface- DataInput
- Throws:
- IOException
 
- 
readLine- Specified by:
- readLinein interface- DataInput
- Throws:
- IOException
 
- 
readLong- Specified by:
- readLongin interface- DataInput
- Throws:
- IOException
 
- 
readShort- Specified by:
- readShortin interface- DataInput
- Throws:
- IOException
 
- 
readUnsignedByte- Specified by:
- readUnsignedBytein interface- DataInput
- Throws:
- IOException
 
- 
readUnsignedShort- Specified by:
- readUnsignedShortin interface- DataInput
- Throws:
- IOException
 
- 
readUTF- Specified by:
- readUTFin interface- DataInput
- Throws:
- IOException
 
- 
seekDescription copied from interface:RandomAccessContentSets the file-pointer offset, measured from the beginning of this file, at which the next read or write occurs.The offset may be set beyond the end of the file. Setting the offset beyond the end of the file does not change the file length. The file length will change only by writing after the offset has been set beyond the end of the file. Notice: If you use RandomAccessContent.getInputStream()you have to re-get the InputStream after callingRandomAccessContent.seek(long)- Specified by:
- seekin interface- RandomAccessContent
- Parameters:
- pos- the offset position, measured in bytes from the beginning of the file, at which to set the file pointer.
- Throws:
- IOException- if- posis less than- 0or if an I/O error occurs.
 
- 
setLengthDescription copied from interface:RandomAccessContentSets the length of this content.If the newLengthargument is smaller thanRandomAccessContent.length(), the content is truncated.If the newLengthargument is greater thanRandomAccessContent.length(), the content grows with undefined data.- Specified by:
- setLengthin interface- RandomAccessContent
- Parameters:
- newLength- The desired content length
- Throws:
- IOException- If an I/O error occurs
 
- 
skipBytes- Specified by:
- skipBytesin interface- DataInput
- Throws:
- IOException
 
- 
write- Specified by:
- writein interface- DataOutput
- Throws:
- IOException
 
- 
write- Specified by:
- writein interface- DataOutput
