This class provides a container for an in‐core representation of a signed 64‐bit big‐endian integer. It supports a complete set of value semantic operations, including copy construction, assignment, equality comparison, bsl::ostream printing, and BDEX serialization. Note that the copy constructor and copy‐assignment operator are provided by the compiler. Any object of this class can be converted to an Int64 allowing comparison with any other object of this class. This class is exception neutral with no guarantee of rollback: if an exception is thrown during the invocation of a method on a pre‐existing object, the object is left in a valid state, but its value is undefined. In no event is memory leaked. Finally, aliasing (e.g., using all or part of an object as both source and destination) is supported in all cases.

class BigEndianInt64;

Member Functions

Name

Description

operator=

Store in this object the specified value as a signed 64‐bit big‐endian integer, and return a reference to this modifiable object.

bdexStreamIn

Assign to this object the value read from the specified input stream using the specified version format, and return a reference to stream. If stream is initially invalid, this operation has no effect. If version is not supported, this object is unaltered and stream is invalidated but otherwise unmodified. If version is supported but stream becomes invalid during this operation, this object has an undefined, but valid, state. Note that no version is read from stream. See the bslx package‐level documentation for more information on BDEX streaming of value‐semantic types and containers.

bdexStreamOut

Write this value to the specified output stream using the specified version format, and return a reference to stream. If stream is initially invalid, this operation has no effect. If version is not supported, stream is invalidated but otherwise unmodified. Note that version is not written to stream. See the bslx package‐level documentation for more information on BDEX streaming of value‐semantic types and containers.

print

Format this object to the specified output stream at the (absolute value of) the optionally specified indentation level and return a reference to stream. If level is specified, optionally specify spacesPerLevel, the number of spaces per indentation level for this and all of its nested objects. If level is negative, suppress indentation of the first line. If spacesPerLevel is negative, format the entire output on one line, suppressing all but the initial indentation (as governed by level). If stream is not valid on entry, this operation has no effect.

operator BloombergLP::bslmf::NestedTraitDeclaration<BigEndianInt64, HasPrintMethod>

Declare that this type is trivially copyable.

operator bsls::Types::Int64

Return the value stored in this object as a bsls::Types::Int64 in the native byte‐order.

Description

BloombergLP::bdlb::operator!=

Return true if the specified lhs and rhs BigEndianInt64 objects do not have the same value, and false otherwise. Two BigEndianInt64 objects do not have the same value if and only if the respective integral network byte‐order values that they represent do not have the same value.

BloombergLP::bdlb::operator==

Return true if the specified lhs and rhs BigEndianInt64 objects have the same value, and false otherwise. Two BigEndianInt64 objects have the same value if and only if the respective integral network byte‐order values that they represent have the same value.
