Method Detail

setLimit

public void setLimit(int limit)

Maximum amount of data in this buffer. If -1 or not set, the buffer will grow to {ARRAY_MAX_SIZE. Can be smaller than the current buffer size ( which will not shrink ). When the limit is reached, the buffer will be flushed (if out is set) or throw exception.

Parameters:

limit - The new limit

getLimit

public int getLimit()

getLimitInternal

protected int getLimitInternal()

getStart

public int getStart()

Returns:

the start position of the data in the buffer

getEnd

public int getEnd()

setEnd

public void setEnd(int i)

getOffset

public int getOffset()

setOffset

public void setOffset(int off)

getLength

public int getLength()

Returns:

the length of the data in the buffer

isNull

public boolean isNull()

indexOf

public int indexOf(String src,
                   int srcOff,
                   int srcLen,
                   int myOff)

recycle

public void recycle()

Resets the chunk to an uninitialized state.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

hash

public int hash()

getBufferElement

protected abstract int getBufferElement(int index)
