void	setProperty(String name, String value) Set a property used by this validator.
void	validate(DbObject reference, DbObject target, DiffContext ctx) Validate the target database object (against the reference object if necessary).
boolean	validates(String fieldName) Ask whether the database object's validator is responsible for validating the specified field name.
boolean	validatesFullObject() Asks whether the database object's validator is responsible for validating the entire DbObject.

Method Detail

validate

void validate(DbObject reference,
              DbObject target,
              DiffContext ctx)

Validate the target database object (against the reference object if necessary). Store the validation results on the DiffContext.

Parameters:

reference - DbObject

target - DbObject

ctx - DiffContext

setProperty

void setProperty(String name,
                 String value)

Set a property used by this validator. Validator properties provided in the schema reference XML files will be set on the validator using this method.

Parameters:

name - String

value - String

getProperty

String getProperty(String name)

Get the current value of a validator property, as set using setProperty(String, String).

Parameters:

name - String

Returns:

String

getPropertyNames

Set<String> getPropertyNames()

Get the complete set of validator properties in use.

validates

boolean validates(String fieldName)

Ask whether the database object's validator is responsible for validating the specified field name. This only applies to simple properties - not DbObject instances which should provide their own validators.

Parameters:

fieldName - String

Returns:

boolean

validatesFullObject

boolean validatesFullObject()

Asks whether the database object's validator is responsible for validating the entire DbObject. If true, then differences are not reported (e.g. table missing from database) as it is the validator's role to worry about presence. If validation and differences are required then report false - even if the validator works at the full object (rather than property) level.

Returns:

true if missing or unexpected database objects should not be reported by differencing logic.
