Modifier and Type	Method and Description
static byte[]	arrayToBytes(Array arr, DataType type, java.nio.ByteOrder order)
static Array	bytesToArray(byte[] in, DataType type, java.nio.ByteOrder order)
static DataType	getAttributeDataType(Attribute attribute, DataType.Signedness signedness)
static DataType	largestOf(DataType... dataTypes)
static DataType	nextLarger(DataType dataType) Returns the smallest numeric data type that: can hold a larger integer than dataType can if integral, has the same signedness as dataType Argument Result BYTE SHORT UBYTE USHORT SHORT INT USHORT UINT INT LONG UINT ULONG LONG DOUBLE ULONG DOUBLE Any other data type Just return argument The returned type is intended to be just big enough to hold the result of performing an unsigned conversion of a value of the smaller type. static int rank(DataType dataType) Methods inherited from class java.lang.Object clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait Constructor Detail FilterHelpers public FilterHelpers() Method Detail bytesToArray public static Array bytesToArray(byte[] in, DataType type, java.nio.ByteOrder order) arrayToBytes public static byte[] arrayToBytes(Array arr, DataType type, java.nio.ByteOrder order) nextLarger public static DataType nextLarger(DataType dataType) Returns the smallest numeric data type that: can hold a larger integer than dataType can if integral, has the same signedness as dataType Argument Result BYTE SHORT UBYTE USHORT SHORT INT USHORT UINT INT LONG UINT ULONG LONG DOUBLE ULONG DOUBLE Any other data type Just return argument The returned type is intended to be just big enough to hold the result of performing an unsigned conversion of a value of the smaller type. For example, the byte value -106 equals 150 when interpreted as unsigned. That won't fit in a (signed) byte, but it will fit in a short. Parameters: dataType - an integral data type. Returns: the next larger type. getAttributeDataType public static DataType getAttributeDataType(Attribute attribute, DataType.Signedness signedness) rank public static int rank(DataType dataType) largestOf public static DataType largestOf(DataType... dataTypes) Skip navigation links Overview Package Class Tree Deprecated Index Help Prev Class Next Class Frames No Frames All Classes Summary: Nested | Field | Constr | Method Detail: Field | Constr | Method
