vectorBlock

Create a vectorBlock Object

Description

These functions create a "vectorBlock" or lengthBlock object, which are a descriptions of a block of binary data. These can be used as part of a description of a binary format.

Usage

vectorBlock(block = ASCIIchar, length = 1)
lengthBlock(length = integer4, block = ASCIIchar, blockLabel = "block")

Arguments

`block`	An object derived from the `"memBlock"` class, e.g., an `"atomicBlock"` object.
`length`	The number of `block` objects in the overall binary block.
`blockLabel`	A label to name the block component of the `"lengthBlock"` object.

Details

These objects describe a block of binary data that consists of a repeating sub-block. The sub-block can be any type of "memBlock" object.

There is also a predefined ASCIIline block, which is a block of single-byte characters terminated by a newline character.

Value

A "vectorBlock" or lengthBlock object.
