Detailed Description

This page details functions for managing an Enumeration Errors object.

Enumeration

The following code iterates over an enumeration errors object:

for (XnEnumerationErrorsIterator it = xnEnumerationErrorsGetFirst(pList); 
    xnEnumerationErrorsIteratorIsValid(it); 
    it = xnEnumerationErrorsGetNext(it))
{
    const XnProductionNodeDescription* pCurrDesc = xnEnumerationErrorsGetCurrentDescription(it);
    XnStatus nCurrError = xnEnumerationErrorsGetCurrentError(it);
    ...
}

Typedef Documentation

An object that holds errors during an enumeration process.

typedef struct XnModuleError* XnEnumerationErrorsIterator

Represents an iterator for an XnEnumerationErrors object.


Function Documentation

XN_C_API XnStatus XN_C_DECL xnEnumerationErrorsAdd ( XnEnumerationErrors pErrors,
const XnProductionNodeDescription pDesc,
XnStatus  nError 
)

Adds an error to the object.

Parameters:
pErrors[in] Enumeration Errors object.
pDesc[in] Description of the failing module.
nError[in] The enumeration error that occurred.

Allocates an enumeration errors object.

Parameters:
ppErrors[out] The allocated object

Clears an Enumeration Errors object from all errors in it.

Parameters:
pErrors[in] Enumeration Errors object.
XN_C_API void XN_C_DECL xnEnumerationErrorsFree ( const XnEnumerationErrors pErrors)

Frees an enumeration errors object

Parameters:
pErrors[in] Parameter description

Gets the description of the node from current error.

Parameters:
it[in] The iterator to the error.

Gets the enumeration error caused when enumerating the node.

Parameters:
it[in] The iterator to the error.

Gets an iterator to the first error in the object.

Parameters:
pErrors[in] Enumeration Errors object.

Gets an iterator to the next error in the object.

Parameters:
it[in] An iterator to an error in the object.

Checks if an iterator is valid (i.e. points to a real error)

Parameters:
it[in] The iterator to check.
XN_C_API XnStatus XN_C_DECL xnEnumerationErrorsToString ( const XnEnumerationErrors pErrors,
XnChar *  csBuffer,
XnUInt32  nSize 
)

Returns a string representation of the Enumeration Errors object.

Parameters:
pErrors[in] Enumeration Errors object.
csBuffer[in] A char buffer to be filled.
nSize[in] Size of the char buffer.
