Detailed Description

This class handles the conversion between a byte stream and an English readable view of the data in an OMT Tree.

Member Enumeration Documentation

enum DtDatatypeManager::DtDatatypeEnum

Enumerator:

ENUMERATED	A basic datatype such as int or bool.
COMPLEX	An Enumeration that maps an integer to a string value.
ARRAY	A collection of different data types in one.
VARIANT	A collection of the same datatype in one.
FIXED	A datatype that could be of a different type at runtime.
DEFINED	A fixed set of a collection of different data types.
DATATYPE_MAX	An INTERNALLY defined set of different data types.

Member Function Documentation

virtual void DtDatatypeManager::addDelimiterMap	(	const DtString &	datatype,
		const DtString &	delimiter
	)		`[virtual]`

A delimiter is the divider between elements in an array, complex, or fixed.

For example, if the delimiter is :. Then an array of ints would look like this: 4:67:2:1

virtual DtString DtDatatypeManager::convertStringTreeToString ( DtStringTree * ) [virtual]

Flatten a string tree.

This basically converts any function created by createStringTreeRep to the same result as getStringRep

virtual DtStringTree* DtDatatypeManager::createStringTreeRep	(	const DtDatatypeFedNode *	currFedNode,
		const void *	value,
		int	size,
		int &	returnSize,
		unsigned int	currentOffset = `0`,
		DtObjectHistory *	= `0`
	)		`[virtual]`

Creates a string tree from a datatype.

This can be a single string if this is a simple datatype, or a more elaborate structure on more complex datatype. Note that this is a 'create' function and the caller is responsible for deleting the string tree

Parameters:

datatypeName	The Name of the datatype that is defined in value
value	A series of bytes from the network.
size	The total size of bytes in value
returnSize	This gets filled with the actual number of bytes read. If there is a problem and the number of bytes is too many, this returns -1.

virtual int DtDatatypeManager::getComplexDatatypeCount	(	DtComplexComponentNode *	compNode,
		DtComplexDatatypeNode *	parentNode,
		const void *	value,
		int	valueSize,
		int	alreadyRead,
		const DtStringTree *	strTree = `0`,
		const DtStringTree *	parentTree = `0`
	)		`[protected, virtual]`

Complex and array datatypes have an undetermined amount of elements This function returns the correct element count.

Parameters:

parentTree A filled string tree.

virtual DtString DtDatatypeManager::getStringRep	(	const DtDatatypeFedNode *	currFedNode,
		const void *	value,
		int	size,
		int &	returnSize
	)		`[virtual]`

Get the string representation from the datatype and the value The size input is the size that the network says the datatype is, but that gets modified to the actual size read.

Parameters:

datatypeName	The Name of the datatype that is defined in value
value	A series of bytes from the network.
size	The total size of bytes in value
returnSize	This gets filled with the actual number of bytes read. If there is a problem and the number of bytes is too many, this returns -1.

virtual bool DtDatatypeManager::modifyRepMapping	(	const DtString &	datatype,
		const DtString &	rep
	)		`[virtual]`

Modify a mapping.

Do not do anything if the mapping does not exist returns true if a mapping is modified, false otherwise
