Module aerospike::expressions::bitwise

Bitwise Aerospike Filter Expressions.

Functions

• add
  Create expression that adds value to byte[] bin starting at bitOffset for bitSize and returns byte[]. BitSize must be <= 64. Signed indicates if bits should be treated as a signed number. If add overflows/underflows, BitwiseOverflowActions is used.
• and
  Create expression that performs bitwise “and” on value and byte[] bin at bitOffset for bitSize and returns byte[].
• count
  Create expression that returns integer count of set bits from byte[] bin starting at bitOffset for bitSize.
• get
  Create expression that returns bits from byte[] bin starting at bitOffset for bitSize.
• get_int
  Create expression that returns integer from byte[] bin starting at bitOffset for bitSize. Signed indicates if bits should be treated as a signed number.
• insert
  Create expression that inserts value bytes into byte[] bin at byteOffset and returns byte[].
• lscan
  Create expression that returns integer bit offset of the first specified value bit in byte[] bin starting at bitOffset for bitSize.
• lshift
  Create expression that shifts left byte[] bin starting at bitOffset for bitSize and returns byte[].
• not
  Create expression that negates byte[] bin starting at bitOffset for bitSize and returns byte[].
• or
  Create expression that performs bitwise “or” on value and byte[] bin at bitOffset for bitSize and returns byte[].
• remove
  Create expression that removes bytes from byte[] bin at byteOffset for byteSize and returns byte[].
• resize
  Create expression that resizes byte[] to byteSize according to resizeFlags and returns byte[].
• rscan
  Create expression that returns integer bit offset of the last specified value bit in byte[] bin starting at bitOffset for bitSize. Example:
• rshift
  Create expression that shifts right byte[] bin starting at bitOffset for bitSize and returns byte[].
• set
  Create expression that sets value on byte[] bin at bitOffset for bitSize and returns byte[].
• set_int
  Create expression that sets value to byte[] bin starting at bitOffset for bitSize and returns byte[]. BitSize must be <= 64.
• subtract
  Create expression that subtracts value from byte[] bin starting at bitOffset for bitSize and returns byte[]. BitSize must be <= 64. Signed indicates if bits should be treated as a signed number. If add overflows/underflows, BitwiseOverflowActions is used.
• xor
  Create expression that performs bitwise “xor” on value and byte[] bin at bitOffset for bitSize and returns byte[].
