Default constructor.

Member Function Documentation

const char* apache::geode::client::CacheableString::asChar ( ) const

inlineinherited

Return the string that backs this CacheableString as a char *.

This shall throw an exception if the underlying string is a wchar_t* – the caller should use typeId to determine the actual type, or isWideString to find whether this is a wide-character string.

Exceptions

IllegalStateException if the underlying string is a wchar_t *

const wchar_t* apache::geode::client::CacheableString::asWChar ( ) const

inlineinherited

Return the string that backs this CacheableString as a wchar_t *.

This shall throw an exception if the underlying string is a char* – the caller should use typeId to determine the actual type, or isWideString to find whether this is indeed a wide-character string.

Exceptions

IllegalStateException if the underlying string is a char *

virtual int32_t apache::geode::client::CacheableFileName::classId ( ) const

virtual

Return the classId of the instance being serialized.

This is used by deserialization to determine what instance type to create and deserialize into.

Factory method for creating an instance of CacheableString from a C string of given length by taking ownership of the string without making a copy.

The string should have been allocated using the standard C++ new operator.

This should be used only for ASCII strings.

CAUTION: use this only when you really know what you are doing.

		int32_t	len = `0`
	)

inlinestaticinherited

Factory method for creating an instance of CacheableString from a wide-character C string of given length by taking ownership of the string without making a copy.

The string should have been allocated using the standard C++ new operator.

This should be used for non-ASCII strings.

CAUTION: use this only when you really know what you are doing.

virtual int8_t apache::geode::client::Serializable::DSFID ( ) const

virtualinherited

return the Data Serialization Fixed ID type.

This is used to determine what instance type to create and deserialize into.

Note that this should not be overridden by custom implementations and is reserved only for builtin types.

Reimplemented in apache::geode::client::Struct, and apache::geode::client::CacheableUndefined.

virtual Serializable* apache::geode::client::CacheableFileName::fromData ( DataInput & input )

virtual

deserialize this object Throw IllegalArgumentException if the packed CacheableString is not less than 64K bytes.

Reimplemented from apache::geode::client::CacheableString.

bool apache::geode::client::CacheableString::isCString ( ) const

inlineinherited

Returns true if the underlying string is a normal C string.

bool apache::geode::client::CacheableString::isWideString ( ) const

inlineinherited

Returns true if the underlying string is a wide-character string.

uint32_t apache::geode::client::CacheableString::length ( ) const

inlineinherited

Return the length of the contained string.

virtual int32_t apache::geode::client::CacheableString::logString	(	char *	buffer,
		int32_t	maxLength

Reimplemented from apache::geode::client::CacheableKey.

virtual uint32_t apache::geode::client::CacheableString::objectSize ( ) const

virtualinherited

return the size in bytes of the instance being serialized.

This is used to determine whether the cache is using up more physical memory than it has been configured to use. The method can return zero if the user does not require the ability to control cache memory utilization. Note that you must implement this only if you use the HeapLRU feature.

Reimplemented from apache::geode::client::Serializable.

virtual bool apache::geode::client::CacheableString::operator== ( const CacheableKey & other ) const

virtualinherited

return true if this key matches other.

Implements apache::geode::client::CacheableKey.

void apache::geode::client::SharedBase::preserveSB ( ) const

inherited

Atomically increment reference count.

int32_t apache::geode::client::SharedBase::refCount ( )

inlineinherited

Returns: the reference count

static void apache::geode::client::Serializable::registerPdxSerializer ( PdxSerializerPtr pdxSerializer )

staticinherited

Register the PDX serializer which can handle serialization for instances of user domain classes.

See also: PdxSerializer

static void apache::geode::client::Serializable::registerPdxType ( TypeFactoryMethodPdx creationFunction )

staticinherited

register an Pdx instance factory method for a given type.

Exceptions

IllegalStateException if the typeName has already been registered, or there is an error in registering the type; check errno for more information in the latter case.

static void apache::geode::client::Serializable::registerType ( TypeFactoryMethod creationFunction )

staticinherited

register an instance factory method for a given type.

During registration the factory will be invoked to extract the typeId to associate with this function.

Exceptions

IllegalStateException if the typeId has already been registered, or there is an error in registering the type; check errno for more information in the latter case.

void apache::geode::client::SharedBase::releaseSB ( ) const

inherited

Atomically decrement reference count, the SharedBase object is automatically deleted when its reference count goes to zero.

virtual void apache::geode::client::CacheableFileName::toData ( DataOutput & output ) const

virtual

serialize this object

Reimplemented from apache::geode::client::CacheableString.

const char* apache::geode::client::CacheableString::toString ( )

inlineinherited

Display this object as c string.

In this case, it returns the same value as asChar() when underlying type is a char* and returns the same value as asWChar() cast to char* when the underlying type is a wchar_t*. To handle this correctly the user should find the actual type by calling typeId() or isWideString() and cast to the correct type accordingly. Note: this is a debugging API, not intended for getting the exact value of the CacheableString. In a future release this may return a more summary representation. This is historical. It is preferred that the user call logString or asChar/asWChar, depending on the need.

virtual CacheableStringPtr apache::geode::client::CacheableString::toString ( ) const

inlinevirtualinherited

Display this object as 'string', which depends on the implementation in the subclasses.

The default implementation renders the classname.

The return value may be a temporary, so the caller has to ensure that the SharedPtr count does not go down to zero by storing the result in a variable or otherwise.

Reimplemented from apache::geode::client::Serializable.

virtual int8_t apache::geode::client::CacheableFileName::typeId ( ) const

virtual

return the typeId byte of the instance being serialized.

This is used by deserialization to determine what instance type to create and deserialize into.

Reimplemented from apache::geode::client::CacheableString.
