Checker

public Checker(DeclareErrorOrWarning deow)

Create a Checker for a declare error or declare warning.

Parameter:

deow - the declare error or declare warning for which to create the checker munger

Methodendetails

isError

public boolean isError()

getMessage

public String getMessage(Shadow shadow)

specializeOn

public void specializeOn(Shadow shadow)

Angegeben von:

specializeOn in Klasse ShadowMunger

implementOn

public boolean implementOn(Shadow shadow)

Beschreibung aus Klasse kopiert: ShadowMunger

Implement this munger at the specified shadow, returning a boolean to indicate success.

Angegeben von:

implementOn in Klasse ShadowMunger

Parameter:

shadow - the shadow where this munger should be applied

Gibt zurück:

true if the implement was successful

match

public boolean match(Shadow shadow,
 World world)

Determine if the Checker matches at a shadow. If it does then we can immediately report the message. Currently, there can never be a non-statically determinable match.

Setzt außer Kraft:

match in Klasse ShadowMunger

Parameter:

shadow - the shadow which to match against

world - the world through which to access message handlers

compareTo

public int compareTo(Object other)

Gibt zurück:

• +1 if this is greater than other
• -1 if this is less than other
• 0 if this is not comparable to other

mustCheckExceptions

public boolean mustCheckExceptions()

Beschreibung aus Klasse kopiert: ShadowMunger

Gibt zurück:

true if munger has to check that its exceptions can be thrown based on the shadow

getThrownExceptions

public Collection<ResolvedType> getThrownExceptions()

Angegeben von:

getThrownExceptions in Klasse ShadowMunger

Gibt zurück:

a Collection of ResolvedTypes for all checked exceptions that might be thrown by this munger

equals

public boolean equals(Object other)

Setzt außer Kraft:

hashCode

public int hashCode()

Setzt außer Kraft:

parameterizeWith

public ShadowMunger parameterizeWith(ResolvedType declaringType,
 Map<String,UnresolvedType> typeVariableMap)

Parameterize the Checker by parameterizing the pointcut

Angegeben von:

concretize

public ShadowMunger concretize(ResolvedType theAspect,
 World world,
 PerClause clause)
