class bionet.utils.misc.SerialBuffer(get, n=1)

Serial buffer class.

n : int

Number of initial entries to load into buffer.

Methods

clear()	Empty buffer.
read(n=1)	Read n elements from buffer.
replenish(n=1)	Replenish buffer to contain at least n elements.

__init__(get, n=1)

Methods

__init__(get[, n])
clear()	Remove all elements from the buffer.
read([n])	Read a block of data (default length = 1).
replenish([n])	Attempt to replenish the buffer such that it contains at least n entries (but do not throw any exception if insufficient data can be obtained).
