ErrorHandler is the abstract base class for Validators.

Method Detail

error

public abstract void error(ValidationException exception)
                    throws SchemaException

Receive notification of an error.

For example, a validator would use this callback to report the violation of a validity constraint. The default behaviour is to take no action.

The validator must continue to provide normal validation after invoking this method: it should still be possible for the application to process the document through to the end. If the application cannot do so, then the parser should report a fatal error.

Filters may use this method to report other, non-JSON errors as well.

Parameters:

exception - The error information encapsulated in a validation exception.

Throws:

SchemaException - Any JSON exception, possibly wrapping another exception.

hasError

public boolean hasError()

Get the final result of the validation.

The default value is false. If the validator has called the {#handleError} method then it return true.

Returns:

true if there was an error during the validation process.

assembleException

@Deprecated
public abstract void assembleException()
                                            throws ValidationException

Deprecated.

Throws an assembled exception after the validator finished the processing.

Implementation of this method MUST throw an Exception if the {#error()} method was called on this instance before.

Throws:

ValidationException - when this instance wraps an error message(s).
