Detailed Description

The SamValidator class contains static methods for validating the SAM/BAM Record and each of its fields.

The generic isValid method performs all of the other validations. The SamValidator methods return whether or not what is being validated is valid. True means it is valid, false means it is not. The specifics of the invalid value(s) are contained in the SamValidationErrors object that is passed in (by reference) to the method. The specific errors can be pulled out of that object. TODO: VALIDATION METHODS STILL NEED TO BE ADDED, and isValid does not yet validate all fields!!!

bool SamValidator::isValidRname	(	const char *	rname,
		SamValidationErrors &	validationErrors
	)			[static]

Validate the rname without validating against the header.

Validation for RNAME is: a) cannot be 0 length. b) [
@=] are not allowed in the name.

Parameters:

	rname	reference name to be validated.
	validationErrors	status to append any errors too.

Returns:

true if it is valid, false and appends to SamValidationErrors if it is not

bool SamValidator::isValidRname	(	SamFileHeader &	samHeader,
		const char *	rname,
		SamValidationErrors &	validationErrors
	)			[static]

Validate the reference name including validating against the header.

1) Cross validate the rname and the header. 2) perform the validation in the method that doesn't take the header.

Parameters:

	samHeader	header associated with the rname to be validated.
	rname	reference name to be validated.
	validationErrors	status to append any errors too.

Returns:

true if it is valid, false and appends to SamValidationErrors if it is not

Validate the sequence, but not against the cigar or quality string.

Validation against cigar is done in isValidCigar. Validation against the quality string is done in isValidQuality. TODO: currently no validation is done in this method.

Parameters:

	samRecord	record whose sequence should be validated.
	validationErrors	status to append any errors too.

Parameters:

	samRecord	record whose tags should be validated.
	validationErrors	status to append any errors too.

Returns:
