Member Function Documentation

void foedus::storage::hash::HashMetadataSerializer::assign ( const foedus::externalize::Externalizable * other )

inlineoverridevirtual

Polymorphic assign operator.

This should invoke operator= of the derived class.

Parameters

[in] other assigned value. It must be dynamic-castable to the assignee class.

Implements foedus::externalize::Externalizable.

Definition at line 87 of file hash_metadata.hpp.

const char* foedus::storage::hash::HashMetadataSerializer::get_tag_name ( ) const

inlineoverridevirtual

Returns an XML tag name for this object as a root element.

We might want to give a different name for same externalizable objects, so this is used only when it is the root element of xml.

Implements foedus::externalize::Externalizable.

Definition at line 87 of file hash_metadata.hpp.

ErrorStack foedus::storage::hash::HashMetadataSerializer::load ( tinyxml2::XMLElement * element )

overridevirtual

Reads the content of this object from the given XML element.

Parameters

[in] element the XML element that represents this object

Expect errors due to missing-elements, out-of-range values, etc.

Implements foedus::externalize::Externalizable.

ErrorStack foedus::storage::hash::HashMetadataSerializer::save ( tinyxml2::XMLElement * element ) const

overridevirtual

Writes the content of this object to the given XML element.

Parameters

[in] element the XML element that represents this object

Expect only out-of-memory error. We receive the XML element this object will represent, so this method does not determine the XML element name of itself. The parent object determines children's tag names because one parent object might have multiple child objects of the same type with different XML element name.
