ShapeByteReader

java.lang.Object
- com.partnersoft.formats.shapefile.ShapeByteReader

```
public class ShapeByteReader
extends java.lang.Object
```
Reads the low-level values used in the shapefile format.
This is a wrapper around DynamicByteArray that translates the values used in shapes (generally little-endian 4-byte ints and 8-byte floats) and in SDE binary (generally a compressed integer format that is then scaled and offset to generate a coordinate value).
It also includes some convenience functions for standard structures such as points and boxes (bounds).

- Method Detail
  - readInteger
```
public int readInteger()
```
    Read an Integer, which is stored as a 4-byte signed little-endian int.
  - readDouble
```
public double readDouble()
```
    Read a Double, which is stored as an 8-byte little-endian float.
  - readIntegerArray
```
public int[] readIntegerArray(int size)
```
    Reads the given number of integers as an array, in the same manner as readInteger().
  - readDoubleArray
```
public double[] readDoubleArray(int size)
```
    Reads the given number of doubles as an array, in the same manner as readDouble().
  - readPackedInteger
```
public long readPackedInteger()
```
    Read a packed integer value. This is the format used for coordinates in Arc/SDE. Note that generally these are not absolute values, but are instead meant to be added to the previous value as a relative offset. The result is then scaled and offset using spatial reference parameters.
    The higher precision allowed by Arc/SDE 9.2 means that this requires an 8-byte result value.
    
    Returns:
    8-byte integer decoded from variable-length byte value
  - readPoint
```
public XyPoint readPoint()
```
    Read an XyPoint as two Doubles.
  - readPointZ
```
public XyzPoint readPointZ()
```
    Read an XyzPoint as three Doubles.
  - readBounds
```
public XyBounds readBounds()
```
    Read an XyBounds as four doubles.
  - skip
```
public void skip(int count)
```
    Skip the given number of bytes.
  - getBytes
```
public DynamicByteArray getBytes()
```
    Returns the underlying DynamicByteArray.
