CreateContentBuffer() [1/2]

static bool DE_ValidationUtils::CreateContentBuffer ( const TCollection_AsciiString & thePath, occ::handle< NCollection_Buffer > & theBuffer )

static

Creates buffer by reading from file stream for content checking.

Parameters

[in]	thePath	file path for reading
[out]	theBuffer	output buffer with file content

Returns

true if successful, false otherwise

CreateContentBuffer() [2/2]

static bool DE_ValidationUtils::CreateContentBuffer ( std::istream & theStream, occ::handle< NCollection_Buffer > & theBuffer )

static

Creates buffer by reading from input stream for content checking.

Parameters

[in,out]	theStream	input stream to read from (position will be restored)
[out]	theBuffer	output buffer with stream content

Returns

true if successful, false otherwise

ValidateConfigurationNode()

static bool DE_ValidationUtils::ValidateConfigurationNode ( const occ::handle< DE_ConfigurationNode > & theNode, const occ::handle< Standard_Type > & theExpectedType, const TCollection_AsciiString & theContext, const bool theIsVerbose = true )

static

Validates that configuration node is not null and matches expected type.

Parameters

[in]	theNode	configuration node to validate
[in]	theExpectedType	expected RTTI type
[in]	theContext	context string for error messages
[in]	theIsVerbose	if true, sends detailed error messages via Message::SendFail

Returns

true if node is valid, false otherwise

ValidateDocument()

static bool DE_ValidationUtils::ValidateDocument ( const occ::handle< TDocStd_Document > & theDocument, const TCollection_AsciiString & theContext, const bool theIsVerbose = true )

static

Validates that TDocStd_Document handle is not null.

Parameters

[in]	theDocument	document to validate
[in]	theContext	context string for error messages
[in]	theIsVerbose	if true, sends detailed error messages via Message::SendFail

Returns

true if document is not null, false otherwise

ValidateFileForReading()

static bool DE_ValidationUtils::ValidateFileForReading ( const TCollection_AsciiString & thePath, const TCollection_AsciiString & theContext, const bool theIsVerbose = true )

static

Checks if file exists and is readable.

Parameters

[in]	thePath	file path to check
[in]	theContext	context string for error messages
[in]	theIsVerbose	if true, sends detailed error messages via Message::SendFail

Returns

true if file exists and is readable, false otherwise

ValidateFileForWriting()

static bool DE_ValidationUtils::ValidateFileForWriting ( const TCollection_AsciiString & thePath, const TCollection_AsciiString & theContext, const bool theIsVerbose = true )

static

Checks if file location is writable (file may or may not exist)

Parameters

[in]	thePath	file path to check
[in]	theContext	context string for error messages
[in]	theIsVerbose	if true, sends detailed error messages via Message::SendFail

Returns

true if location is writable, false otherwise

ValidateReadStreamList()

static bool DE_ValidationUtils::ValidateReadStreamList ( const DE_Provider::ReadStreamList & theStreams, const TCollection_AsciiString & theContext, const bool theIsVerbose = true )

static

Validates read stream list, warns if multiple streams.

Parameters

[in]	theStreams	read stream list to validate
[in]	theContext	context string for error messages
[in]	theIsVerbose	if true, sends detailed error/warning messages

Returns

true if stream list is valid, false otherwise

ValidateWriteStreamList()

static bool DE_ValidationUtils::ValidateWriteStreamList ( DE_Provider::WriteStreamList & theStreams, const TCollection_AsciiString & theContext, const bool theIsVerbose = true )

static

Validates write stream list, warns if multiple streams.

Parameters

[in]	theStreams	write stream list to validate
[in]	theContext	context string for error messages
[in]	theIsVerbose	if true, sends detailed error/warning messages

true if stream list is valid, false otherwise

WarnLengthUnitNotSupported()

static bool DE_ValidationUtils::WarnLengthUnitNotSupported ( const double theLengthUnit, const TCollection_AsciiString & theContext, const bool theIsVerbose = true )

static

Sends warning when format doesn't support length unit scaling.

Parameters

[in]	theLengthUnit	length unit value to check
[in]	theContext	context string for warning messages
[in]	theIsVerbose	if true, sends warning messages via Message::SendWarning

Returns

true always (this is just a warning)
