Detailed Description

An XML based encoder.

The underlying transfer encoding is an XML document. The encoder is initialized with a stream which will receive the XML document as calls are made on the encoder.

Member Function Documentation

closeElement()

void XmlEncode::closeElement ( const ElementId &  elemId )

virtual

End the current element in the encoding.

The current element must match the given annotation or an exception is thrown.

Parameters

elemId

is the given (expected) annotation for the current element

Implements Encoder.

openElement()

void XmlEncode::openElement ( const ElementId &  elemId )

virtual

Begin a new element in the encoding.

The element will have the given ElementId annotation and becomes the current element.

Parameters

elemId

is the given ElementId annotation

Implements Encoder.

References elementTagIsOpen.

writeBool()

void XmlEncode::writeBool ( const AttributeId &  attribId, bool  val  )

virtual

Write an annotated boolean value into the encoding.

The boolean data is associated with the given AttributeId annotation and the current open element.

Parameters

attribId	is the given AttributeId annotation
val	is boolean value to encode

Implements Encoder.

writeSignedInteger()

void XmlEncode::writeSignedInteger ( const AttributeId &  attribId, intb  val  )

virtual

Write an annotated signed integer value into the encoding.

The integer is associated with the given AttributeId annotation and the current open element.

Parameters

attribId	is the given AttributeId annotation
val	is the signed integer value to encode

Implements Encoder.

writeSpace()

void XmlEncode::writeSpace ( const AttributeId &  attribId, const AddrSpace *  spc  )

virtual

Write an address space reference into the encoding.

The address space is associated with the given AttributeId annotation and the current open element.

Parameters

attribId	is the given AttributeId annotation
spc	is the address space to encode

Implements Encoder.

writeString()

void XmlEncode::writeString ( const AttributeId &  attribId, const string &  val  )

virtual

Write an annotated string into the encoding.

The string is associated with the given AttributeId annotation and the current open element.

Parameters

attribId	is the given AttributeId annotation
val	is the string to encode

Implements Encoder.

writeUnsignedInteger()

void XmlEncode::writeUnsignedInteger ( const AttributeId &  attribId, uintb  val  )

virtual

Write an annotated unsigned integer value into the encoding.

The integer is associated with the given AttributeId annotation and the current open element.

Parameters

attribId	is the given AttributeId annotation
val	is the unsigned integer value to encode

Implements Encoder.
