Throws:

AssertionException - is thrown if a syntactic or semantic error occurs

Method Detail

isConsistent

public boolean isConsistent()

Indicates wether the assertion is consistent or wether it may contain some inconsistencies. If there are inconsistecies the details can be retrieved by calling getWarnings().

Returns:

true if there are no inconsitencies, false otherwise.

getWarnings

public List<AssertionWarning> getWarnings()

Retrieves the warnings associated with this assertion describing possible inconsitencies in the assertion.

Returns:

a List of AssertionWarning objects describing any warnings/inconsistencies in the assertion represented by this object. This List will be non-empty if isConsistent() returns false, and empty otherwise.

toString

public String toString()

Overrides:

toString in class Assertion

Returns:

the String representation of the assertion as specified in the constructor.

prettyString

public String prettyString()

Used for "pretty printing" an assertion. The assertion string is re-constructed from the parsed data.

Returns:

a pretty printed version of the assertion.

printWarnings

public void printWarnings()

Deprecated. printWarnings

Used to print all warnings that were generated while parsing the assertion. Used only for debugging purposes.
