BitsPerValue

Declaration
public abstract int BitsPerValue { get; }
Property Value
Type Description
System.Int32

The number of bits used to store any given value. Note: this does not imply that memory usage is bitsPerValue * #values as implementations are free to use non-space-optimal packing of bits.

Count

The number of values.

NOTE: This was size() in Lucene.

Declaration
public abstract int Count { get; }
Property Value
Type Description
System.Int32

HasArray

Returns true if this implementation is backed by a native .NET array.

Declaration
public virtual bool HasArray { get; }
Property Value
Type Description
System.Boolean

Get(Int32, Int64[], Int32, Int32)

Bulk get: read at least one and at most len longs starting from index into arr[off:off+len] and return the actual number of values that have been read.

Declaration
public virtual int Get(int index, long[] arr, int off, int len)
Parameters
Type Name Description
System.Int32 index
System.Int64[] arr
System.Int32 off
System.Int32 len
Returns
Type Description
System.Int32

GetArray()

Expert: if the bit-width of this reader matches one of .NET's native types, returns the underlying array (ie, byte[], short[], int[], long[]); else, returns null. Note that when accessing the array you must upgrade the type (bitwise AND with all ones), to interpret the full value as unsigned. Ie, bytes[idx]&0xFF, shorts[idx]&0xFFFF, etc.

Declaration
public virtual object GetArray()
Returns
Type Description
System.Object

RamBytesUsed()

Return the in-memory size in bytes.

Declaration
public abstract long RamBytesUsed()
Returns
Type Description
System.Int64
