Method Detail

getComponentIdentifierTypeDeclarationsMap

public ReadOnlyMap<NameIdentifier,TypeDeclaration> getComponentIdentifierTypeDeclarationsMap()

Description copied from interface: PossRepImplementation_V0105

Gets a map of component names to corresponding type declarations. The keys in the map are the names of the components of this possrep. The values in the map are the type declaration objects corresponding to the named component. The map can be empty, if this is a possrep that does not consist of components.

Specified by:

getComponentIdentifierTypeDeclarationsMap in interface PossRepImplementation_V0105

Returns:

a map of component/type names.

getComponentNameMap

public MyReadOnlyMap<java.lang.String,java.lang.String> getComponentNameMap()

Description copied from interface: PossRepImplementation

Gets a map of component/type names. The keys in the map are the names of the components of this possrep. The values in the map are the typenames corresponding to (the values for) the named component. Since both the keys and the values in the map are all names, they must both be all uppercase. The map can be empty, if this is a possrep that does not consist of components.

Specified by:

getComponentNameMap in interface PossRepImplementation

Returns:

a map of component/type names.

getComponentTypeDeclarationsMap

public ReadOnlyMap<java.lang.String,TypeDeclaration> getComponentTypeDeclarationsMap()

Description copied from interface: PossRepImplementation

Gets a map of component names to corresponding type declarations. The keys in the map are the names of the components of this possrep. The values in the map are the type declaration objects corresponding to the named component. The map can be empty, if this is a possrep that does not consist of components.

Specified by:

getComponentTypeDeclarationsMap in interface PossRepImplementation

Returns:

a map of component/type names.

valueFromComponentValues

public ValueBuffer valueFromComponentValues(java.util.Map<java.lang.String,ValueBuffer> componentValueMap)
                                     throws InvalidValueException

Description copied from interface: PossRepImplementation

Returns a ValueBuffer holding the value of the type that this PossRepImplementation is for, and that corresponds to the component values given in the componentValueMap argument.

Specified by:

valueFromComponentValues in interface PossRepImplementation

Parameters:

componentValueMap - A Map holding component names and their corresponding values, held in a ValueBuffer.

Returns:

a ValueBuffer holding the value of the type that this PossRepImplementation is for, and that corresponds to the component values given in the componentValueMap argument.

Throws:

InvalidValueException - If the given mapping of component names to component values does not constitute a valid value for the type

valueFromExternalRepresentation

public ValueBuffer valueFromExternalRepresentation(java.lang.String value,
                                                   Heading nonScalarHeading)
                                            throws InvalidValueException

Description copied from interface: PossRepImplementation

Convert a value of this possrep's type to internal format. The implementation is responsible for ensuring that the result is within bounds with the possrep's type's minimum or maximum logical size (and thus with the corresponding minimum and maximum physical encoding size). If the type is variable-length, then any length may be chosen for the ByteBuffer returned, as long as the encoding of the value fits within that byteBuffer length. If the encoding of a value takes less bytes than the chosen length, then the remaining bytes must be filled with null bytes (0x00). Failing to obey this rule will subvert certain checksum computations that are done internally by SIRA_PRISE, and thus cause it to possibly produce wrong results. Note that if a type is variable-length, then the first four bytes in the returned ScalarValueBuffer's ByteBuffer must hold the logical length of the value.

Specified by:

valueFromExternalRepresentation in interface PossRepImplementation

Parameters:

value - the value in external format.

nonScalarHeading - The heading defining the specific nonScalar type, if the type is nonScalar and the value is a body value alone

Returns:

the value in internal format.

Throws:

InvalidValueException - If the textual representation does not represent a value of the possrep's type.

valueFromIdentifierComponentValues

public ValueBuffer valueFromIdentifierComponentValues(java.util.Map<NameIdentifier,ValueBuffer> componentValueMap)
                                               throws InvalidValueException

Description copied from interface: PossRepImplementation_V0105

Returns a ValueBuffer holding the value of the type that this PossRepImplementation is for, and that corresponds to the component values given in the componentValueMap argument.

Specified by:

valueFromIdentifierComponentValues in interface PossRepImplementation_V0105

Parameters:

componentValueMap - A Map holding component names and their corresponding values, held in a ValueBuffer.

Returns:

a ValueBuffer holding the value of the type that this PossRepImplementation is for, and that corresponds to the component values given in the componentValueMap argument.

Throws:

InvalidValueException - If the given mapping of component names to component values does not constitute a valid value for the type

valueToEscapedExternalRepresentation

public java.lang.String valueToEscapedExternalRepresentation(ValueBuffer valueBuffer,
                                                             Heading nonScalarHeading)

Description copied from interface: PossRepImplementation

Converts a value in internal format to the appropriate textual representation of that value for this possrep. In this method, all tokens of the SIRA_PRISE metalanguage must be output in 'escaped' format, i.e. each '(' character in the representation of the value must be represented as the string "\(", each ')' as a "\)" and each '\' as a "\\". Observe that this does NOT apply to the opening and closing parentheses that delimit the value of a component.

Specified by:

valueToEscapedExternalRepresentation in interface PossRepImplementation

Parameters:

valueBuffer - The value in internal format.

nonScalarHeading - The heading defining the specific nonScalar type, if the type the value held in valueBuffer is of, is indeed nonScalar. Can be left null for scalar types, as they are not "defined" by a Heading.

Returns:

The string representation of the given value, for this possrep.

valueToEscapedExternalRepresentationVerbose

public java.lang.String valueToEscapedExternalRepresentationVerbose(ValueBuffer valueBuffer,
                                                                    Heading nonScalarHeading)

Description copied from interface: PossRepImplementation_V0105

Converts a value in internal format to the appropriate textual representation of that value for this possrep, including the surrounding typename (i.e. the integer 1 is rendered as INT(1)). In this method, all tokens of the SIRA_PRISE metalanguage must be output in 'escaped' format, i.e. each '(' character in the representation of the value must be represented as the string "\(", each ')' as a "\)" and each '\' as a "\\". Observe that this does NOT apply to the opening and closing parentheses that delimit the value of a component.

Specified by:

valueToEscapedExternalRepresentationVerbose in interface PossRepImplementation_V0105

Parameters:

valueBuffer - The value in internal format.

nonScalarHeading - The heading defining the specific nonScalar type, if the type the value held in valueBuffer is of, is indeed nonScalar. Can be left null for scalar types, as they are not "defined" by a Heading.

Returns:

The string representation of the given value, for this possrep.

valueToExternalRepresentation

public java.lang.String valueToExternalRepresentation(ValueBuffer valueBuffer,
