java.lang.Objectjava.io.InputStream
com.tangosol.io.AbstractReadBuffer.AbstractBufferInput
com.tangosol.io.MultiBufferReadBuffer.MultiBufferInput
public class MultiBufferReadBuffer.MultiBufferInput
An implementation of the BufferInput interface that is backed by a series of the underlying ReadBuffer BufferInput objects.
Constructor Summary | |
---|---|
MultiBufferReadBuffer.MultiBufferInput()
Default constructor. |
Method Summary | |
---|---|
protected void |
adjust(int cb)
Adjust the offset of this BufferOutput based on a write that by-passed this BufferOutput's own super-class implementation that is responsible for maintaining the offset. |
protected ReadBuffer.BufferInput |
getIn()
Obtain the underlying BufferOutput. |
int |
read()
Read the next byte of data from the InputStream. |
int |
read(byte[] ab,
int of,
int cb)
Read up to cb bytes from the input stream and store
them into the passed array ab starting at offset
of . |
ReadBuffer |
readBuffer(int cb)
Read cb bytes and return them as a ReadBuffer object. |
byte |
readByte()
Read a byte value. |
char |
readChar()
Read a char value. |
double |
readDouble()
Read a double value. |
float |
readFloat()
Read a float value. |
int |
readInt()
Read an int value. |
long |
readLong()
Read a long value. |
int |
readPackedInt()
Read an int value using a variable-length storage-format. |
long |
readPackedLong()
Read a long value using a variable-length storage-format. |
String |
readSafeUTF()
Read a variable-length encoded UTF packed String. The major differences between this implementation and DataInput is that this supports null String values and is not limited to 64KB UTF-encoded values. |
short |
readShort()
Read a short value. |
int |
readUnsignedShort()
Read an unsigned short value. |
String |
readUTF()
Reads a String value. |
void |
reset()
Rewind this stream to the position at the time the AbstractReadBuffer.AbstractBufferInput.mark(int)
method was last called on this InputStream. |
void |
setOffset(int of)
Specify the offset of the next byte to read from the underlying ReadBuffer. |
int |
skipBytes(int cb)
Skips over up to the specified number of bytes of data. |
protected void |
sync()
After traversing an underlying WriteBuffer boundary, or otherwise changing the offset significantly, sync between this BufferOutput's absolute position and an underlying BufferOutput's relative position. |
