Operation is_external

Computed from the value of the uri attribute: True if the data is stored externally to the record, as
indicated by `uri'. A copy may also be stored internally, in which case `is_expanded' is also true.

Declaration :

• Uml : + is_external() : Boolean
• C++ : public: bool is_external()
• Java : public boolean is_external()

Operation is_inline

Computed from the value of the data attribute.
True if the data is stored in expanded form, ie within the EHR itself.

Declaration :

• Uml : + is_inline() : Boolean
• C++ : public: bool is_inline()
• Java : public boolean is_inline()

Operation is_compressed

Computed from the value of the compression_algorithm attribute:
True if the data is stored in compressed form.

Declaration :

• Uml : + is_compressed() : Boolean
• C++ : public: bool is_compressed()
• Java : public boolean is_compressed()

Operation has_integrity_check

Computed from the value of the integrity_check_algorithm attribute:
True if an integrity check has been computed.

Declaration :

• Uml : + has_integrity_check() : Boolean
• C++ : public: bool has_integrity_check()
• Java : public boolean has_integrity_check()

Operation size

Original size in bytes of unencoded encapsulated data. I.e. encodings such
as base64, hexadecimal etc do not change the value of this attribute.

Declaration :

• Uml : + size() : Integer
• C++ : public: int size()
